4th April

Sunrise on the Sunday after the first full moon following the vernal equinox.

Calculating the date of Easter is tricky. You have to first understand how the earth moves around the sun and then how the moon moves around the earth. You then have to know how to fit of all this into a standardised counting system before you can finally decide on a date that everyone agrees upon.

How would you ever begin to teach children about all these horribly technical things that even adults have trouble comprehending?

Well, you might start with a story.
