Easter is a great Christian holiday symbolizing the Resurrection of Christ. Before Easter, a strict fast lasts, which lasts seven weeks. This holiday is not attached to a specific date, because every year it happens on a different day, but certainly after the vernal equinox.

Step 1
Easter is the main Christian holiday. It contains the whole meaning of the Christian faith. The date of a holiday can be determined in several ways. Easter takes place after the vernal equinox. If you have a lunar calendar at hand, then it will not be difficult to determine the date of Easter for this year. You need to find the day of the full moon, which falls after the vernal equinox. The closest Sunday to this day will be the date of Easter. If you do not have a lunar calendar or need to calculate the date of Easter for a specific year, then you can use special formulas.
Step 2
Here is the formula by which you can calculate the date of Easter for any year. Let's analyze it below.
First, we calculate the remainder of dividing the number of the year by 19, using a calculator or long division, whichever is more convenient for you. We take this value as A.
Step 3
In the same way, we calculate the remainder of dividing the number of the year by 4. The value is taken as B.
Step 4
We calculate the number B as the remainder of dividing the number of the year by 7.
Step 5
We calculate the number G as the remainder of the division by 30 of the value 19 * A + 15.
Step 6
We calculate the number D as the remainder of the division by 7 of the value 2 * B + 4 * B + 6 * G + B.
Step 7
In order to immediately calculate the day of Easter, it is necessary to estimate the sum of the values of Г and D. If it is more than 10, then the date of Easter will be Г + Д - April 9, otherwise 22 + Г + Д March. The date turned out according to the old style, in order to transfer to the new style, you need to add 13.
