The vernal equinox is usually March 20th or 21st. But the church decided that’s always March 21st. No exceptions, even if the actual equinox is a day earlier. It’s like saying your birthday is always July 4th because you like fireworks. So we have a fake equinox, a fake moon, and a real headache. But somehow, this messy system has worked for 1,700 years.

This means Easter can fall anywhere between March 22nd and April 25th. That’s a 35-day window of chaos. It’s like letting a toddler choose the date for a family reunion. March 22nd is the earliest possible Easter (very rare, last in 1818), while April 25th is the latest (last in 1943, next in 2038). If you love consistency, you have chosen the wrong holiday.

Why Does This Moon Madness Even Exist?

Here’s the wild part: Easter is tied to the Jewish holiday of Passover. Jesus was a Jew, and his Last Supper was a Passover seder. The early Christians wanted Easter close to Passover, which is also tied to the lunar calendar. So, problem solved: just use the moon. But then the Council of Nicaea in 325 AD said, “Nope, we don’t want to follow the Jewish calendar exactly,” and invented their own moon math. It’s like saying, “I love pizza, but I’ll only eat pizza I invented while blindfolded.”

And here’s a surprise: the Eastern Orthodox Church uses a different calendar (the old Julian calendar). So their Easter often falls later than the Western Easter. Some years, barely any Christians agree on when to eat chocolate. The only thing they share is confusion and a healthy supply of marshmallow Peeps.
