pagans celebrate the seasons in similar ways that witches do and so around christmas time there is celebrations to do with the sun, and how the seasons have turned, at around christmas time there is celebration in how yule or winter solstice the longest night of the year, after that the return of the sun and summer is known to follow.
but i think anyway there is no problem in witches celebrating christmas as well as there more witchcraft style beliefs, some witches believe in christ and mary magdalene also and it being part of the mysteries.
the question might be best answered a lot of witches do celebrate christmas.
