Is your school system in session today?

Today is Good Friday in the Christian religion. I just found out that my half-sister has the day off. I’m confused as to why. It’s not a federal holiday. Other Christian-but-not-federal holidays don’t get the day off (Ash Wednesday, Feast of the Assumpion, All Saints, etc).

Are the kids in your area in school today? Is it just my half-sister’s town?
