why is christmas celebrated in december

Well, the holiday of Christmas is celebrated in December because it was originally a pagan holiday that was later adopted by the Christian religion. The pagan holiday was celebrated on December 25th as a way to honor the winter solstice, which is the shortest day of the year. Christians later adopted this holiday and celebrated it on the same day to commemorate the birth of Jesus Christ. So, Christmas has been celebrated on December 25th ever since.
