Description

Technical Field

[0001] This application relates to the field of calendar pendant technology, and in particular to a rotary 100-year calendar. Background Technology

[0002] An active calendar was introduced in the 4th issue of the 1984 magazine "Amateur Astronomy" (pages 16-18). This active calendar has the following five major drawbacks:

[0003] ① It divides each disk into 35 equal parts, and the central angle of each sector is (360÷35=10.2857 degrees), which is not an integer. This means that there is a certain error in the degree of each sector's central angle, and the accumulated error will increase, making it inaccurate when comparing.

[0004] ② Currently, people usually regard Sunday as the first day of the week and place it on the far left of the week. However, in the activity calendar, any week number from Sunday to Saturday can be used as the first day of the week. This is inconvenient and unfamiliar to view and can also cause some trouble.

[0005] ③ In the month column of the activity calendar, regardless of whether it is a long month, a short month, or even February in a leap year, the day sequence displayed in the "Date" window is always (1-31). It can be seen that the displayed day sequence cannot change with the search month, that is, the day sequence cannot be completely consistent with the length of each month in the Gregorian calendar.

[0006] ④ It mixes the "month and year" of common years and the "month and year" of leap years together. When searching, you must first confirm whether the year you are looking for is a common year or a leap year before you can search for January and February of a common year or January and February of a leap year.

[0007] ⑤ It cannot display the last two digits of a single year, but it can simultaneously display the last two digits of three or four years in which the first day of every month within a century is the same. It also cannot display the month sequence individually, but it can simultaneously display the month sequence of two or three months in which the first day of every month is the same, such as November, March, and February in a common year, or April, July, and January in a leap year. Therefore, it is not clear enough which year and month are displayed.

[0008] Therefore, a rotating 100-year calendar was proposed to solve the above problems. Utility Model Content

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] This application provides a rotary calendar for a hundred-year cycle to solve the problems in related technologies, such as the mixing of common years and leap years, the fact that the day order does not change with the month order, and the inability to clearly display the specific year corresponding to the month order, which leads to inconvenient information retrieval.

[0047] Please see Figures 1-13 A rotating 100-year calendar, comprising a face plate 1, a base plate 2, and a central axis 3.

[0048] The top and bottom of the central axis 3 are fixedly connected to the center of the front plate 1 and the base plate 2 respectively; from top to bottom, the front plate 1 and the base plate 2 are provided with a coaxial year display plate 4, day sequence plate 5, separator plate 6 and year-month plate 7;

[0049] The year display panel 4, the day display panel 5, and the year-month display panel 7 are all movably set with the central axis 3; the year display panel 4 has a first channel 12; the day display panel 5 has a second channel 13 and a sixth channel 17; the separator panel 6 is fixedly connected to the central axis 3, and has a third channel 14, a fourth channel 15, a fifth channel 16, and a seventh channel 18.

[0050] The faceplate 1 has a day sequence display window 8 corresponding to the day sequence dial 5, the sixth channel 17 and the third channel 14, a year sequence display window 9 corresponding to the year single display dial 4, the year and month dial 7, the fourth channel 15 and the first channel 12, a month display window 10 corresponding to the year and month dial 7, the fifth channel 16 and the second channel 13, and a leap year display window 11 corresponding to the year and month dial 7 and the seventh channel 18.

[0051] With the above settings, during the rotation process, the rotating year-month and year display dials 4 can determine the exact year to be searched. Then, rotating the day sequence dial 5 will allow you to query the day sequence information for the twelve months of that year. The day sequence changes as the month sequence is searched, clearly showing the relationship between the month sequence and the specific year.

[0052] During rotation, the day sequence display window 8 displays the day sequence information of the day sequence disk 5, which includes information from the 1st to the 28th, as well as the day sequence information displayed on the year-month disk 7 through the sixth channel 17 and the third channel 14, which only includes the 29th, 30th, and 31st. Thus, the two are combined to fully display the complete day sequence information for each month.

[0053] The year display window 9 is used to display the year segment information of the year display disk 4, as well as the specific year information displayed on the year and month disk 7 through the fourth channel 15 and the first channel 12. The information corresponding to the multiple first channels 12 on the year and month disk 7 will also change as the year display disk 4 is rotated.

[0054] The month display window 10 is used to display month information on the year-month disk 7 through the fifth channel 16 and the second channel 13; the leap year display window 11 is used to display leap year information on the year-month disk 7 through the seventh channel 18.

[0055] In some preferred embodiments, the specific structure described above is further explained:

[0056] The front panel 1, base panel 2, and divider panel 6 are all circular and have the same diameter; the day display panel 5 and the month-year display panel 7 are also circular, with the diameter of the day display panel 5 being smaller than that of the month-year display panel 7, and the diameter of the month-year display panel 7 being smaller than that of the front panel 1; the day display panel 5 covers the day display window 8 and the month display window 10. A weekday arrangement area is engraved on the front panel 1 near the day display window 8.

[0057] The day sequence panel 5 has a day sequence display area and a month display area located outside the day sequence display area; the second channel 13 is located in the month display area, and the sixth channel 17 is located in the day sequence display area.

[0058] The year and month disc 7 has an annular day sequence area, an annular month sequence area, an annular leap year area, and an annular year area arranged sequentially from the center to the periphery; the projections of the sixth channel 17 and the third channel 14 are projected onto the annular day sequence area; the projections of the second channel 13 and the fifth channel 16 are projected onto the annular month sequence area; the projections of the seventh channel 18 and the leap year display window 11 are projected onto the annular leap year area; and the projections of the fourth channel 15 and the first channel 12 are projected onto the annular year area.

[0059] Both the day display window 8 and the month display window 10 are arc-shaped windows; the year display panel 4 includes a first circular part and a sector-shaped part; the radius of the arc segment of the sector-shaped part is equal to the radius of the face panel 1; the diameter of the first circular part is smaller than the diameter of the circle corresponding to the inner arc of the day display window 8.

[0060] The number of first channels 12 on the year display disk 4 is four, and they are arranged from the inside to the outside in the radial direction of the fan-shaped part, and are located at different radii. The first channels 12 are not connected to each other. The fan-shaped part has four year segment display areas corresponding to the first channels 12.

[0061] The above details the specific function of each turntable, the different information displayed on it, and the interaction between different windows. This structural form demonstrates that it can utilize different projection relationships for display.

[0062] In some preferred embodiments, a limiting disc 19 is also included. The limiting disc 19 is disposed between the date disc 5 and the year display disc 4, and is fixedly connected to the central shaft 3. The limiting disc 19 and the main disc 1 form a receiving space for the movement of the year display disc 4. The limiting disc 19 has a second disc portion and two blocking portions, which extend radially along the main disc 1. The blocking portions are provided with connecting rods or connecting blocks connected to the main disc 1 in the radial direction to form the receiving space. The above structure illustrates the specific limiting form of the rotation space of the year display disc 4.

[0063] In some preferred embodiments, the outer edges of the face plate 1, base plate 2, and divider plate 6 are each provided with a first operating notch 20 to facilitate the rotation of the year-month dial 7; the outer edges of the face plate 1, base plate 2, and divider plate 6 are each provided with a second operating notch 21 to facilitate the rotation of the year display dial 4. These features facilitate the rotation of the year-month dial 7 and the year display dial 4. The day sequence dial 5 can be rotated through the day sequence display window 8 or the month display window 10.

[0064] Example 1

[0065] The following explains in detail how the information is compiled on each turntable, and provides a specific example:

[0066] Part 1: Compilation of the Year and Month Chart – Determining the correspondence between the 1st of each month and the weekday within a century:

[0067] 1. The relationship between months and days of the week:

[0068] ① If we group the months with the same first day of the week in a leap year together, and then group them according to the week number, we can determine seven groups of leap year months corresponding to Sunday through Saturday. The first group is October; the second is May; the third is August, and February (leap year); the fourth is November and March; the fifth is June; the sixth is September and December; and the seventh is April, July, and January (leap year). That is to say, if January 1st of a leap year is a Sunday, then July 1st and April 1st of that year are also Sundays, October 1st is a Monday, May 1st is a Tuesday, and so on.

[0069] ② If we group the months in a common year whose first day of the month falls on the same day of the week together, and then group them according to the week number, we can determine the seven groups of months in a common year that correspond to Sunday through Saturday. The first group is October and January; the second group is May; the third group is August; the fourth group is November, March, and February; the fifth group is June; the sixth group is September and December; and the seventh group is April and July. That is to say, if January 1st of a common year is a Monday, then October 1st of that year is also a Monday, May 1st is a Tuesday, August 1st is a Wednesday, and so on.

[0070] ③ According to the length of each month in the Gregorian calendar, they can be divided into three categories: short months are the first category; long months (excluding January) are the second category; and January and February are the third category.

[0071] 2. The Relationship Between Century Years and Weekdays - Determining the Correspondence Between January 1st of Each Century Year and Weekday within a 400-Year Period:

[0072] We know that years ending in 100 are called century years (1800 and 1900 are called the 18th and 19th century years respectively). According to the current Gregorian calendar, years divisible by 4 are leap years. However, century years, while divisible by 4, are not leap years if they are not divisible by 400. Therefore, there are three non-leap years in a 400-year cycle: 1900, 2100, and 2200 are common years, while 2000 is a leap year. This cleverly eliminates the extra three days counted over 400 years. In 400 years, there are actually only 97 leap years, totaling 146,097 days, which is exactly a multiple of seven. This means that every 400 years, the Gregorian calendar date and corresponding weekday return to their original numbers. In other words, the weekday of any century year is the same as the weekday of any century year obtained by adding or subtracting a multiple of 4. Therefore, we group these century years together. Following this principle, century years can be divided into four groups. For example: Century years 15 and 19 belong to the first group; 16 and 20 to the second group; 17 and 21 to the third group; and 18 and 22 to the fourth group. Additional century years can be added to each group as needed. Additionally, the extra day in a leap year is artificially placed at the end of February. For any century year, if there are 24 leap years within a century from January 1st of this century year (common year) to January 1st of the next century year (common year or leap year), totaling 36,524 days (36,524 = 5217 x 7 + 5), then the weekday number is increased by 5 (or decreased by 2). If there are 25 leap years within a century from January 1st of this century year (leap year) to January 1st of the next century year (common year), totaling 36,525 days (36,525 = 5217 x 7 + 6), then the weekday number is increased by 6 (or decreased by 1). Therefore, if we know what day of the week January 1st is in a certain century within 400 years, we can deduce what day of the week January 1st is in the other three centuries within those 400 years.

[0073] 3. The relationship between January 1st and the weekdays over the past century - Determining the correspondence between January 1st and the weekdays over the past century:

[0074] Within a century, for any given year, if we move from January 1st of that year (common year) to January 1st of the following year (common year or leap year), the interval is 365 days, which is a multiple of seven plus one. Therefore, according to the seven-day week cycle and the sequential arrangement of months, if January 1st of a year (common year) is a Monday, then January 1st of the following year (common year or leap year) will be a Tuesday. In a leap year, if we move from January 1st of that year (leap year) to January 1st of the following year (common year), the interval is 366 days, which is a multiple of seven plus two. If January 1st of a year (leap year) is a Monday, then January 1st of the following year (common year) will be a Wednesday. Therefore, whenever January 1st of a year (common year) transitions to January 1st of the following year (common year or leap year), the weekday number is incremented. Every four years, a leap year transitions, and the weekday number jumps by one day from January 1st of the current year (leap year) to January 1st of the following year (common year). Thus, within a century, if we know the weekday of January 1st of a certain century year (e.g., 2000), we can calculate the weekday of January 1st of every other year within that century.

[0075] Once we know the weekday number corresponding to the sequence number of January 1st each year, we can deduce the weekday numbers corresponding to the other six month sequences in a common year (or leap year) based on the seven-day week cycle and the month sequence numbering.

[0076] In a rotary calendar, we originally placed the last two digits of the year in the vertical column corresponding to Saturday in the weekday calendar. This meant we first had to determine which month corresponds to Saturday each year before we could fill in the corresponding column with the last two digits of the year. Therefore, we were able to determine the correspondence between the 1st of each month and the weekday for a century. (See...) Figure 10 and Figure 13 ).

[0077] The original plan was to place the window for the last two digits of the year on the dial above the vertical column containing Saturday (or in the opposite corner of Saturday). First, identify the month sequence corresponding to Saturday for each year. Then, fill in the last two digits of that year in the vertical column corresponding to that month. This method is used for years within the last 100 years (00 to 99). When the last two digits of a year appear in the window, the month window will show the correspondence between the 1st of each month (January to December) and Sundays through Saturdays. When the month window on the day dial is aligned with the month we are looking for, we can achieve a comparison of all dates and days of the week for that month and year. However, considering people's left-to-right viewing habits, we rotated the window for the last two digits of the year from the position of Saturday in the vertical column (or from the opposite corner of Saturday) clockwise to the left side of the dial. In this way, the last two digits of each year on the year-month chart must also rotate by an equal angle clockwise in their respective positions. At this point, the month ring on the year-month chart remains stationary.

[0078] 4. In any common year (or leap year), if we know the weekday number corresponding to one of the seven groups of months that correspond to Sunday through Saturday, we can quickly deduce the weekday numbers corresponding to the other six groups of months in that common year (or leap year) based on the seven-day week cycle and the month grouping order.

[0079] II. Compiling the Day Chart – Determining the Correspondence Between Dates and Weekdays within a Month:

[0080] 1. The relationship between dates and days of the week within a month:

[0081] ① To determine the correspondence between dates and days of the week within a month, we can consider the following approach: Group dates with the same day of the week together, and then group them according to their week number sequence. This will create seven groups. Based on the continuity of the day sequence and the week number, once we can determine the week number corresponding to the first group containing the day number "1", we can then determine the week number corresponding to the other six groups of dates, following the grouping order of the days and the seven-day week cycle.

[0082] ② Within a month, as the first set of day sequences is compared with the fixed Sunday to Saturday in sequence, these seven sets of day sequences will eventually be fixed in the pattern of "6 horizontal rows and 13 vertical columns", thus forming the following three different day sequence modules:

[0083] a. Use a small month and day sequence module labeled (1-30) to display the month and day sequence of the four small months of the year: April, June, September and November.

[0084] b. Use a large month and day sequence module (excluding January) labeled (1-31) to display the month and day sequence of the six large months of the year: March, May, July, August, October, and December.

[0085] C. Use a January and February date sequence module labeled (1-28) to display the month and day sequence of "January and February" in a year.

[0086] ③ Use the "cut-and-paste method" to compare the dates and days of the week in January and February of a common (leap) year.

[0087] a. "Cut": First, fill in the January date sequence (1-31) in a date block on the date sequence disk according to the pattern of "6 horizontal rows and 13 vertical grids". Then, cut out the last three days of January in the fifth horizontal row (i.e., January 29, 30, and 31) and the two days of January "30 and 31" in the sixth horizontal row respectively, thus forming the sixth channel 17.

[0088] b. "Supplement": Keep the year and month plates fixed and only rotate the day plate.

[0089] If you encounter the January month (or January in a leap year) in the January / February month sequence window, fill in and complete the dates "January 29, 30, 31" on the year-month chart using the sixth channel 17. Similarly, fill in and complete the dates "January 30, 31" on the year-month chart using the sixth channel 17.

[0090] If you encounter the February month sequence in the January / February month sequence window, fill in and complete the "29th" of the leap February month sequence in the vertical column on the year-month disk through the window. Then, add two small dots "·" to the two vertical columns after the 29th of the leap February month sequence and to the two vertical columns on the year-month disk through the sixth channel 17, indicating that there are no such two days in the leap February month.

[0091] If you encounter the February month sequence in the January / February month sequence window of a common year, use the sixth channel 17 to place three small dots "·" and two small dots "·" on the year / month chart respectively, indicating that these three days do not exist in February of a common year.

[0092] On the year-month chart, the position of a month's sequence number is actually the position of the 1st of that month. Therefore, the weekday number corresponding to a month's sequence number on the year-month chart is actually the weekday number corresponding to the 1st of that month. On the day chart, in these three day sequence modules, if we place the small windows displaying each month's sequence number below the vertical column where the "1st" is located, then when a month sequence window is aligned with the month sequence number we want to find, we can achieve the comparison of the date and weekday for that specific year and month (see...). Figure 12 ).

[0093] III. Table Design – Integrating the Correspondence Between Year, Month, Day and Weekday:

[0094] Open a "Date" window at the top of the dial, and mark the weekday numbers "Sunday to Saturday" above the seven vertical bars in this window. Open a "Month" window at the bottom of the dial (opposite to the corner of the large Date window). Open a "Last Two Digits of Year" window on the left side of the dial, and mark the first two digits of the year, 20, to the left of this window. Open a small window on the right side of the dial to show whether each year is a common year or a leap year.

[0095] In the year-specific display, we divided the 100-year period (00 to 99) into four time segments, each lasting 28 years. Specifically, 01 to 28 is the first segment; 29 to 56 is the second; 57 to 84 is the third; and 85 to 99 and 00 are the fourth. Note that this 00 is not 2100 but 2000. See... Figure 11 .

[0096] Thus, the rotating 100-year calendar solves the five problems mentioned above:

[0097] ① It divides each disk into 40 equal parts, with the central angle of each sector being 9 degrees. This minimizes errors during compilation, making the comparison more accurate.

[0098] ② A rotating 100-year calendar, with the week numbers "Sunday to Saturday" fixed on the dial, always using Sunday (or Monday) as the first day of the week. However, the seven sets of numbers corresponding to Sunday to Saturday in a common (leap) year will change accordingly as the year and month are searched.

[0099] If we want to combine the weekend holidays (Saturday and Sunday) and make Monday the first day of the week, we only need to make appropriate adjustments to the last two digits of the year in the 28 sets of year-month chart, that is, swap the positions of the last two digits of the year in each set.

[0100] ③ The rotary calendar uses three-month sequence modules to display the length of each month in the Gregorian calendar. The displayed date sequence changes as the month is searched, and it always perfectly matches the length of each month in the Gregorian calendar: long months correspond to (1-31); short months correspond to (1-30); leap February corresponds to (1-29); and February in a common year corresponds to (1-28).

[0101] ④ The rotating 100-year calendar separates the "year and month" of common years and the "year and month" of leap years within a 100-year period. That is to say, as long as you find the year and month you want to look up within the range of 2000 to 2099, you can match the date and day of the week for that year and month without having to consider whether the year you are looking up is a common year or a leap year.

[0102] ⑤ In the rotary calendar, we added a "Year Single Display Panel" and a "Day Single Display Panel." This allows us to cover up the years and months we don't want to see at that time and only display the year, month, and day we want to find. In short, in the rotary calendar, the weekday numbers "Sunday to Saturday" and the last two digits of the year are fixed on the dial. When we find the last two digits of the year we want to find in the last two digits window, the month window will display the seven sets of month sequences for that year (both common and leap years) corresponding to Sunday to Saturday. That is, the weekday corresponding to the 1st of each month in the common (or leap) year. Once we know the weekday corresponding to the 1st of each month in that year, we only need to find the month sequence of the month we want to find in the month window to find the weekday corresponding to all the dates in that month.

[0103] Example 2

[0104] The specific usage method is as follows:

[0105] Example (Usage)

[0106] In a rotating 100-year calendar, apart from the front dial, base dial, and two partition dials which are fixed together, all other dials can rotate. Among them, the front dial, day dial, and year / month dial are all digital dials. Generally, the "year single display dial" rotates only once every 28 years; the "year / month dial" rotates only once a year; the "day dial" rotates once a month; and the "day single display dial" rotates once a day.

[0107] For example: We want to find the date October 28, 2023 and its corresponding day of the week.

[0108] Step 1: Since 2023 falls within the year period "01 to 28", first rotate the "Year Single Display" at the leftmost opening of the dial to reveal the years "01 to 28" through this opening. Then, rotate the "Year and Month" at the rightmost opening of the dial and find the year "23" in the last two digits window of the year. At this point, you will see "23 AD" and "Common Year" on the dial, indicating that the year is a common year. At the same time, the month window of the dial will show seven different common year month sequences, each corresponding to the Sunday to Saturday in the opposite corner of the month sequence. That is, the "Month" window will show the weekday corresponding to the 1st of each month in that year.

[0109] Step 2: In the "Month" window on the dial, touch and rotate the "Day Dial" to find the "October" month in the small month window; at this time, in the "Date" window on the dial, all the days (1-31) of October 2023 and their corresponding days of the week will appear.

[0110] Step 3: Touch and rotate the "Day Chart" by hand. Through the small window in the fourth row of the chart, find today's date, "28". Then, look up along the vertical column where "28" is located. This will show that October 28, 2023, is a Saturday. The "Day Chart" is actually a completely transparent disc. We can not only view the correspondence between all the dates (1-31) and the weekdays in October 2023 through the entire disc, but also view the weekday corresponding to any day in October through the small windows in each row.

[0111] It is worth noting that when rotating the disks, it is best not to disturb the disks that have already been aligned when rotating to a later disk. If an alignment error (or misalignment) is found, it should be corrected (or straightened) immediately. Therefore, we should place an isolation disk between each rotating disk so that the disks do not affect each other when rotating.

[0112] The advent of the Gregorian calendar was a major advancement in calendar systems. With increasingly frequent international exchanges, the Gregorian calendar has gradually become the standard in countries around the world. Therefore, this rotating century-old calendar is bound to be widely adopted. It is not only easy and quick to use, and accurate in its calculations, but also features large numbers that are less likely to strain the eyes. More importantly, it is durable and can last for at least a hundred years. It can be enlarged and used in scenic spots, as well as in waiting halls at airports, train stations, and docks. If made more exquisitely, it can be carried with you while traveling. It requires no oil or electricity, and each year it saves a significant amount of paper used for printing wall calendars, thus contributing to global environmental protection.

[0113] The rotary calendar is simple in structure and easy to manufacture. It can be made into various styles using materials such as metal, plastic, and plexiglass. It does not require a large investment and is a "quick and easy" product that can bring substantial economic benefits to manufacturers.

[0114] This application should also understand that, in reality, the "rotating centennial calendar" can be used to derive the following four centennial calendars. The first expands from 40 equal parts to 66 equal parts, thus reducing the number of separators by two, resulting in slightly smaller numbers. The second expands from 40 equal parts to 84 equal parts, also reducing the number of separators by two, resulting in even smaller numbers. Leap years are mixed (actually arranged separately). The third still uses 40 equal parts, but becomes even smaller. The fourth shrinks from 40 equal parts to 21 equal parts. Of course, this miniaturized centennial calendar can also derive into even more centennial calendars.
