Why not just give each denomination, say, 3 holidays each (christians have xmas, easter and halloween). But the catch being, you can't take off a day that's a holiday of another faith.
You do realize that Jews and Christians celebrate some of the same holidays, right?
Also, All Hallows Eve is very much not a Christian Holy Day.
Yep, but it is entertaining to watch the churches as they try and figure out how to co-opt haloween as well.
Give em another 20 years and they will have it too. And most all will believe it was always that way.
