Im not sure where the minhag comes from but why does chabad refrain from learning Torah on nittel?(xmas) for several hours(Until chatzois)?
I know they say not to give chayus to J**** but wasnt he not even born on december 25th? I dont think non jews even know for sure what date but definitely nowhere near that date. Isnt it just a celebration and not the actual birthdate?
Honestly asking
