'Twas the night before Christmas and not a creature was stirring

[Das's]

Speaking in terms of the Sun, Christmas is that day when the Sun, which has been still for 3 days, turns towards the North and can be visibly seen to have risen for the Northern Hemisphere for the first time in the new season of light for the North

Most of the people live in the N. Hemisphere

The holy lands are in the N. Hemi.
