Easter is the main Christian holiday. It concluded the whole meaning of the Christian faith. A holiday date can be defined in several ways. Easter takes place after the vernal equinox. If you have a moon calendar to determine the date of Easter for this year will not be difficult. Need to find a day of the full moon that falls after the vernal equinox. The closest to the day of resurrection and will be the date of Easter. If you do not have a lunar calendar to calculate the date of Easter for a particular year, you can use the special formulas.

Here is a formula that can calculate the date of Easter for any year. Let us examine it below.

First we calculate the remainder of dividing the year by 19, using calculator or division column, as you prefer. This value is taken for A.

In the same way we calculate the remainder of dividing the year by 4. The value taken for B.

4

Calculated number as the modulo of the number of year 7.

5

Count the number G as the modulo 30 value 19*A + 15.

6

Calculated number as the modulo 7 value 2*B + 4*B + 6*G + B.

To calculate the day of Easter, it is necessary to estimate the sum of G and D. If it is greater than 10, then the Easter date will be D + D - 9 APR, otherwise 22 + G + D Mar. The date turned out, old style, to bring in a new style, you need to add 13.

Note

Easter Catholics and Orthodox celebrate on different days, these dates coincide only once every few years. The reason for this lies in the fact that different countries have chosen different points of reference from the day of the vernal equinox according to the Julian and Gregorian calendars.

Useful advice

If you need to determine the day of the full moon next after the vernal equinox, March 21, it is necessary to add the number of G. Moreover, if G is greater than 10, the full moon will be in April, from the resulting number and subtract 31. If G is less than 10, then the full moon comes in March. Then according to the usual calendar, you can calculate Sunday following this day.
