Abstract

This invention relates to disk calendars for establishing calendar ratios of any period of time. The aim of the invention is to increase the informativeness of the calendar and its ease of use. The calendar consists of three disks interconnected in the center by a common axis. The first disk 1 has the index of years and the index of days of the week. On the second disk, a cutout in the form of a sector with an adjacent month indicator of the year is made against the index of the first disk, and there is a slot against the index of days of the week of the first disk. On the periphery of the second disc, the index of the centuries in the new style and the index of the centuries in the old style are located. The third disk in the form of a segment is supplied with indications of the choice of centuries according to a new and old style, with a slot against the index of the days of the week of the first disk with the index of the month adjacent to it. For work within one century, the second disk is provided with holes, and the third disk has a recess in the form of a insert that can be fixed with a corresponding hole of the second disk. 1 h. n. f-ly, 3 ill. with (L

The invention relates to disk calendars for establishing calendar ratios of any period of time in both the new and the old style.

The purpose of the invention is to increase the informativeness of the calendar and ease of use.

FIG. 1 shows the first disk with

index of years and index of days of the week;

in fig. 2 - the second disk with the index; Lem of the Centuries and the Index of Months; on

FIG. 3 - the third disk with a pointer for the month of the month.

- The perpetual calendar consists of the first disk 1, in which four last years of the index of 2 years are located in the last two digits of the year from 00 to 99, i and the numbers of leap years are in bold lines, and closer to the center have -; there is a pointer 3 days of the week. : The second disk 4 has a notch 5 in the form of: a sector of 1/5 of a circle for viewing seven columns of pointer 2: on the first disk and a pointer of 6 months, with months for leap years marked in bold cipher. For convenience, the number of days is indicated on the sides of this indicator, in the months of this series. The annular slot 7 has a size of 2/5 of the circumference and is located at the level of the pointer 3 of the lower disc. The periphery of disk 4 contains the first two digits of the year — the number of hundreds of years per year, grouped into an index of 8 centuries for new-style definitions and an index of 9 centuries old-style.

The third disk 10 is made in the form of a segment with an annular slot 11 with a size of 1/5 of the circumference at the level of the slot 7 of disk 4 and has an index of 12 numbers of the month.

FIG. 3 numbers 29-31 conventionally not shown. On disk 10, indexes gels 13, 14 of century selection are made to be combined with indexes 8, 9 of the middle disk. In the assembly, the disks are connected to the central center.

On the third disk, a recess 15 can be made in the form of a dent, which, when the disks rotate on the axis, successively coincides with the holes 16 on the second disk, which makes it possible to fix the third disk relative to the second one when determining within a century.

The definitions on the calendar are as follows.

The index 13 of the third disc 10 is set against the first two digits of the required year on the index 8 of the second disc 4 when determining by the new style or index 14 against the digits of index 9 when determining by the old style. Then, rotating the first disk 1 until the two last digits of a given year in index 2 with column 6 of the index containing the month, in slot 11 of the third disk read the days of the week for the numbers of this month located in index 12 of the third disk.

Years differing from each other by 28 years have the same calendar, therefore, are located in one column on the lower disk. The months placed in the same column of the middle disk also have the same calendar.

Nvar calendars, as well as February in simple and leap years do not coincide, therefore for leap years they are highlighted in bold type. It should be borne in mind that in the old style all years ending in 00 are leap years, and in the new style only multiples of 400.

The index of the second disk shows only the numbers 17–20 (the number of hundreds of years per year), the rest can be reduced to this successive addition or subtraction with the number 4, since the Gregorian calendar (new style) has a 400 year period. Similarly, in the old style index 9, only the numbers 14–20 are shown; here the index step is 7, since in the Julian calendar the period is 700 years. 5To reform Peter 1 (1/1 -1700 g.), When

in Russia, the Julian calendar was introduced (old style), in Russia there was a chronology from the “Creation of the world, which, koba, occurred on March 21, 5509 BC. er In addition, until 1492, the beginning of the 0 Oda was taken on March 1, and then to 1/1 - 1700 - 1 September. Therefore, when working with ancient sources, in order to proceed to the old style calculation, it is necessary to subtract 5508 years from the annalistic date, except when the event relates to 5 I-P in the March style — 5507 years is subtracted, or to Saint-December-December at September Briomsko - deducted 5509 years. Definitions for dates BC. er The rule is as follows: a given year is reduced by one, the resulting number is subtracted from the nearest larger, which is a multiple of 700. For the final equivalent year, the definitions are made according to the old style in the usual order.

Terms of use of the calendar - 5.

Example 1. On what day of the week the Great Oct. Br. Of Socialist Revolution (October 25, 1917, old style) was accomplished. Combining pointer 14 on the third disc with digital 19 pointing to 0 9 on the second disc, setting the month 17 of the second disc to figure 17 of the first disc, and reading the number 25 of the third disc in slot 11: Wednesday.

If we make the definitions for 7 November 1917 in a new style, then we set pointer 13 against digit 19 of pointer 8, the last two digits 17 together with month XI, in the window of the upper disk versus 7 chita.m: Wednesday.

0

Example 2. The diary of the war years was found, in which the entry “Oct 5 br, Tuesday was preserved. What year is this record.

Since the diary of 1939-45, then, first setting the pointer 13 against the number 19 of the pointer 8, we successively combine the numbers 39, 40, and so on of the first disk with the month X and look in the third disk window when against the number 5 it will be Tuesday .

Answer: Oct 5 br, Tuesday was in 1943.

Example 3. On the basis of Moscow in the annals of the liaison: m there is on April 4, 6655. “from the creation of the world. To which year and day is the date

Since the month C April does not fall under the above exception, we deduct 5508 years: 6655-5508 1147, Art. style Since index 9 does not contain the number 11, taking into account the index step (7), we will define the definitions for 1847, which has a completely identical calendar with the year.

Answer: The founding of Moscow dates back to 1147, April 4.

Example 4. For the first time the Julian calendar (old style) was introduced in Rome from January 1, 45 BC. 3. What day of the week does this correspond

According to the above rule translate year BC. er in the equivalent year n. e .: 45, decreasing by 1, distance 700-44 656. Since the number 06 is not in the index 9, we make the definition for 2056 old style (20 06 + 7 + 7). We combine pointer 14 with the figure 20 pointer 9, and the number 56 of the first disk with .mix 1, in bold, since 656g. was the leap year, the number 56 on the first disc is marked by thickened lines. In the window of the third disk, against the number 1, we find a fifth.

Answer: January 1, 45 BC. er there was a ptnitsa.

Example 5. From what day will the 21st century begin (January 1, 2000).

Pointer 13 is combined with the numeral 20 of the index of the new style, and the numeral 00 of the first disk is combined with month 1 in bold type, since the year will be a leap year. In the third disk window we find the answer: January 1, 2000 will be Saturday.
