 ``Where the Bishop is, there let the multitude of believers be; even as where Jesus is, there is the Catholic Church'' Ignatius of Antioch, 1st c. A.D

### Date of Easter

Easter will fall on the first Sunday after the first full Moon that falls on or after March 21 (not, as commonly belived, the "first Sunday after the first full Moon in Spring" where Spring is defined as the Season which begins with the astronomical vernal equinox).

The earliest possible date for Easter is March 22, and the latest possible date for it is April 25.

For the mathematically minded, there is an algorithm one can use to determine the date of Easter for any given year. In the following equations:

y=year of Easter
d=day of Easter
m=month of Easter

All variables are integers; drop all remainders from division operations:

c = y / 100

n = y - 19 * ( y / 19 )

k = ( c - 17 ) / 25

i = c - c / 4 - ( c - k ) / 3 + 19 * n + 15

i = i - 30 * ( i / 30 )

i = i - ( i / 28 ) * ( 1 - ( i / 28 ) * ( 29 / ( i + 1 ) ) * ( ( 21 - n ) / 11 ) )

j = y + y / 4 + i + 2 - c + c / 4

j = j - 7 * ( j / 7 )

l = i - j

m = 3 + ( l + 40 ) / 44

d = l + 28 - 31 * ( m / 4 ) Back to The Liturgical Year I: Intro Back to Being Catholic Index
