December is the twelfth and final month of the year in the Julian and Gregorian calendars.
The name "December" comes from the Latin word "decem" meaning "ten", because it was originally the tenth month in the Roman calendar.
In the Northern Hemisphere, December is the first month of winter, while in the Southern Hemisphere it's the first month of summer.

1. Christmas Day (December 25)
2. New Year's Eve (December 31)
