Christmas

Christmas is a holiday in the Christian faiths of Earth. The holiday was originally established to celebrate the birth of the human religious figure Jesus Christ - believed by some humans to be a divine being. The holiday also has roots in ancient human pagan traditions. Humans celebrate the holiday on December 25, which is just after the winter solstice and is also close to the end of the human year.

Many humans continued to celebrate Christmas well into the 24th century. In 2266 the science lab personnel on the USS Enterprise (NCC-1701) held a Christmas party, which Captain Kirk appeared at. After the party he spent an evening with Helen Noel. (TOS episode Dagger of the Mind). In the 24th century, Lt. Sam Redbay was a Starfleet officer regularly celebrated Christmas.
