Computus and My Brother’s Birthday

full_moon_2Week after next, we will have a full moon.

The Purim moon, which precedes the Passover moon.

Easter always falls on the first _________ after the first _____ _____ after the _________ _________ (March 21).*

If you’re looking for an extra-hard Lenten penance to do… How about: Determine whether or not a period exists during which the dates of Easter repeat exactly. If so, determine what the period is.

Now, I know that Easter occurs with some regularity on March 31, since that’s my dear little brother’s birthday. He had an Easter birthday two years ago, and thirteen years ago.

I know that Easter sometimes occurs on March 23, since Easter Sunday, March 23, 2008, will remain forever etched in my memory as the miserable, cold day when the Georgetown Hoyas got knocked out of the NCAA tournament by Steph Curry and the Davidson Wildcats. It just didn’t seem to me that the good Lord Jesus had risen from the dead so that Roy Hibbert’s college career could come to such an abrupt and painful end.

Easter occurs somewhat frequently on March 27, which means that Good Friday and Annunciation Day are the same. I remember that happened in 2005. And it will happen again next year.

The most frequent date of Easter? April 19. But we are living through a 75-year period during which Easter never falls on April 19.

Turns out that the mathematicians of the Middle Ages devised a science called Computus, by which to determine the date of Easter in any given year.

And there is a cycle of Easter dates. They repeat exactly, according to form, in a perfect pattern, very regularly.

Every 5,700,000 years.

  1. You may want to start out on your trip to Martinsville for Sunday’s Masses as it is expected to be very foggy In the morning. It would be helpful if that little bug of your had fog lights. Be safe.
