Well, actually Christmas is not really when he was born either. It's a pagan holiday until the Christians decided to change things hundred of years ago. Good Friday is when he supposedly died and then Easter Sunday is when he rose. Yeah, okay, anyway......it's not exactly been proven when he was born, some have thought some time in the spring. Eh, whatever, lol!
DOB for jesus.. is believed to be in early june sometime... which would oddly enough still be spring.. and no where near the pagan celebration of yule..lol
