This is an article from last year. I'm posting it in case anyone is interested in why certain factions of Christianity celebrate Easter on different dates. The article calls one Catholic Easter, but other Christians I know who are non-Catholic also celebrate on that day, so I added the slash and Christian in the title. Growing up, we had a lot of immigrants from various countries in our neighborhood/city, and so we came to understand that they celebrated at a different time, because they would have their entire extended family over and roast a whole lamb for the Orthodox Easter.
