Who said there isn't math in The Bible.
The article is incorrect. Easter falls on a Sunday between March 22 and April 25 from 1753 to 2400. The article is below for you to check out
From "The Economist"...
"...The earliest possible date for Easter occurs when the full moon falls on March 21st itself, in a year in which March 21st falls on a Saturday. Easter is then celebrated on Sunday March 22nd, a rare event that last happened in 1818 and will next take place in 2285. The latest possible date for Easter occurs when there is a full moon on March 20th, so that the first full moon after March 21st falls a lunar month or 29 days later, on April 18th. If April 18th falls on a Sunday, then the special Sunday rule applies, and Easter is celebrated the following Sunday, or April 25th. This last happened in 1943, and will next happen in 2038. There is therefore a 35-day window in which Easter can fall, depending on the timing of the full moon relative to March 21st."
Got it...and that's just the Western Church...phew.
