Move Halloween?

No, it's not. It's founded in Christianity you ignorant fool. All Hallows Eve was a Christian feast to mark the coming All Hallows (or All Saints Day). Dumbass.
Not quite, it has it origins in Celtic druidism and predates Christianty by at least 5 decades
All the Christian's did was take a pagan holiday and place a "christian" moniker over it

The rituals, the pictures, the severed heads with the souls still burning (we call them Jack-o-lanterns) they all kept

Feel free to believe what you want, but if you want to convince me I'm wrong (wouldn't be the first time) then show me the verses which teach the doctrines that "all hallows" is based on
