If some people don't believe in Christianity, then why do they celebrate Christmas?

Free stuff!

The churches of the world celebrate Christmas, like the Catholics, on the night of December 24-25, as they use not the "Catholic" Gregorian calendar, but the so-called "Novouliana" calendar, which so far coincides with the Gregorian calendar. The discrepancy between these calendars in one day will accumulate by the year 2800 (the discrepancy between the Julian calendar and the astronomical year accumulates in one day in 128 years, the Gregorian one in 3,333 years, and the Novoiuliansky in 40 thousand years).

I moved my question to difficult categories but how come ppl find this question and answer it

What part of "Family, fun, presents and a great dinner" is confusing you?

It's a cultural thing. Do you really believe cupid flies around on Feb. 14th and shoots arrows to make people fall in love?

Those people are not celebrating Christmas. They are celebrating family, presents, love, parties, having a good time.

I dont know. But jesus is not against that someone who does not believe in him celebrate christmas

Christmas was originally a pagan celebration before Christians appropriated it. Christmas trees for example are a pagan tradition and have nothing to do with Christianity.

Furthermore in the modern context it has become both a religious and a secular holiday. It's more of a celebration of materialism than anything else.

Personally I don't like all the wastefulness and pretence so I don't bother, but people are free to celebrate how they like.
