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 )
