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.
3
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.
