That doesn’t even cover the issues of explaining how they figure out what DAY it is every year.
“Okay, so they start by figuring out when the Earth has the most direct sun on the the Tropic of Cancer… no, not the disease, a giant crab… it’s a line of latitude approximately 23°27′ north of Earth’s Equator, right? Yes, there’s math. Anyway, the take the day the sun is strongest and weakest, called the solstices, and … the solstices… It doesn’t matter, It mattered for agriculture back then, especially when spring and fall were, which are the calendar dates in between them, yeah? So the spring equinox ,., that’s what they call the ‘in between solstices,’ equinox… which is March 21st or 22nd or something. What? No no, I am explaining how they figure out when easter is. I haven’t forgotten. So now we know when the spring equinox is, so now we look at a chart of the moon, and figure out when it is full. Full. No, not ‘full of what?’ it’s full meaning that you can see all of in the sky. Well one half of it, actually. The sunlit half, but it’s FACING us, see… The sun lights up and it shows as a circle instead of a crescent or something. Moving on, they look at the FIRST Sunday AFTER the FIRST full moon that occurs on or after the spring equinox. Except if the full moon falls on a Sunday, then Easter is the next Sunday. Why? Well, St. Bede the Venerable, the 6th-century author of Historia ecclesiastica gentis Anglorum (‘Ecclesiastical History of the English People’), maintains that the English word ‘Easter’ comes from Eostre, or Eostrae, the Anglo-Saxon goddess of spring and fertility. That’s where the Spring Equinox comes in. NO I AM NOT MAKING THIS UP!”

That seems like an interesting coding question!
There’s probably a table of the next thousand easters you can use though
