Why does Easter fall on different dates every year?

Furfriends, It is Lent now and MaaMaa is busy trying to clean out the cobwebs to prepare for Easter-- so here's a tidbit for you'all to chew on.

"Everyone knows the date for Easter is different every year. If you've ever wondered how it is determined, here is the answer. Use it to stump your friends! Easter Sunday is the first Sunday following the first full moon that follows the spring equinox. Spring begins on March 20/21.Check your calendar for the next full moon after that date. Easter is the next Sunday. So, this year, the first full moon occurs on March 29th (Monday), and thus the next Sunday, April 4, is Easter Sunday. That rule applies every year." This is from Father Anthony and  I thought it was worth noting-just in case you wondered!How do you spend the weeks leading up to Easter at  your house? Purrs, Tankene Ice Mist
