The purpose of this utility model just be to provide a kind of can obtain from beginning in Christian era year to 10000 years Christian eras easily week, date, month relation perpetual calendar.

The purpose of this utility model is achieved in that it comprises a base plate and two slide plates.Base plate is provided with parallel chute or its equivalent structure, and slide plate slides along chute, wherein has a slide plate to have window; Base plate be provided with week regular domain and ten position years of Christian era number regular domain; The slide plate that has a window be provided with the date regular domain and month regular domain, the spacing of all number or array is identical on these regular domains; The digital spacing that the slide plate that does not have a window is provided with on the regular domain of 1,100 year of Christian era number is the twice of all the other regular domains numeral spacings.It is corresponding one by one when use in each zone.

The utility model date regular domain is a maximum date that exists the middle of the month to arrange 7 numeral formations from 1-31 by every row, February wherein, intercalation February, the moon on the little date only uses 28 by actual fate respectively in above-mentioned regular domain, 29,30, month, regular domain will be divided into 7 arrays in 12 months in 1 year, the foundation of grouping is such, and establishing the end of the year is 0 by 7 remainders that remove, and January is each month extremely by the end of November, the total fate of last day from January 1 meter to this month is removed by 7, the gained remainder is identical is classified as one group, and the remainder at each the end of month is the corresponding remainder values that should add of next month, and is divided into into 7 groups.The 1st group 4, July, the 2nd group 9, Dec, the 3rd group, June, the 4th group 2,3, November, in the 5th group of August, in the 6th group of May, the 7th group 1,10 group by the above order delegation that is arranged in capable of circulation from left to right.

Week, regular domain was in order with seven weeks value circulation align.This regular domain position is over against the window hole location.

Count regular domain bits per inch group position year in ten of Christian eras and represent each ten position times in each century.Arrange 7 bit array since 01 every row, wherein the leap year repeats row and once accounts for two array positions, wherein comes latter two position of last row " 00 " year.Established for January, the February in the leap year of whole a century previous 00 position.Why leap year occupies two positions is because many one day of February in leap year, the date of the preceding one-bit digital in leap year before corresponding February, the date after the back corresponding February in leap year.

1,100 year of Christian era number regular domain since 00 by from small to large the order every row arrange the four figures group.The bits per inch group is represented each a century, and this is that no remainder is a large period because the total fate in 400 years is 7 integral multiple.Thereby every row arranges 4 arrays.Be 7 days integral multiples owing to it's 2 days tos each a century in addition, corresponding all the other each regular domains all are one day one correspondences, so the spacing of this area array is the twice of all the other regular domain word spaces.

Use for convenient, month regular domain the and slide plate with window is not adjacent, and month, each array middle position of regular domain was provided with registration mark, the one side of counting regular domain adjacent with it 1,100 year of Christian era have two seven character-spacings of being separated by to moon sign, count that position year to count regular domain ten of the another side of regular domain and Christian eras adjacent in 1,100 year of Christian era, count each columns group middle position of regular domain position year and count each columns group middle position of regular domain adjacent with it 1,100 year of Christian era ten of Christian eras all to be provided with registration mark.

During use, at first move not slide plate with window, make to count 1,100 year of Christian era in time that to seek on the regular domain to count in position year ten of the alignment line that should times 1100 figure place be occupied and Christian eras on the regular domain and should times ten units occupy the file alignment line and align, moving window slide plate again, make the alignment line that to search month on the month regular domain aim at one, so just can find this moon in this year to go up be what day some day moon line.

The utility model can be made the plane separately, and is cylindrical, also can utilize the surface of other products to be integrated as base plate and this product.

The utility model is according to the calendar rule, and the multiple relation by 7 and 4 is provided with each zone, and by the slide plate slides combination, with the area and the material of minimum, draws from beginning in Christian era year to 10000 years the relation between week, date, month of arbitrary day rapidly.Very convenient, and can use for a long time.Because the utility model can be attached on other product, each vertical or horizontal zone digit all can be lined up annular simultaneously, thereby moulding is changeable, and is widely applicable.

By the following examples and in conjunction with the accompanying drawings structure of the present utility model and using method are further described.

Fig. 1 is the planimetric map of an embodiment of the utility model.

Fig. 2 has the slide plate synoptic diagram of window for the utility model.

Fig. 3 does not have the slide plate synoptic diagram of window for the utility model.

Among Fig. 1, base plate 1 is a plane, and middle part has two chutes 7 on it, is settling slide plate 2 that has window 6 and the slide plate 3 that does not have window on the chute 7 respectively.Slide plate 2 is above slide plate 3, and the top of base plate 1 is a week regular domain 4, this zone be will expression week value seven numerals be arranged in a row by " Sunday " to " Saturday " sequential loop.The below of base plate 1 is ten position years of Christian era to count regular domain 5, and this zone is the time of expression in each a century, promptly from " 00 year " of this a century to " 99 years ", the every row in this zone is by arranging seven figure places in proper order from small to large, wherein the leap year repeats once.Before once corresponding should January in leap year and date in February, after once to date that should be after February in leap year.This zone has 18 rows, comes the 6th, seven of the 18 row in 00 year.

Two slide plates 2,3 can be along chute 7 parallel moving.Window 6 on Fig. 2 middle slide plate 2 is facing to the week regular domain 4 on the base plate 1, and the below of slide plate 2 windows 6 is date regular domains 8, and this zone was from every month No. 1, and every in order row arranges seven figure places, and one until 31 days.Wherein end in February to 28 day, day end intercalation February to 29, month little to 30 days, month greatly to 31 days.Be month regular domain 9 below 2 date of slide plate regular domain 8, this zone with 4, July, 9, Dec, June, 2,3, November, August, May, 1, October these seven arrays and circulation in this order be arranged in a row.
