December in the first month of meteorological winter in the Northern Hemisphere. In the Southern Hemisphere, December is the seasonal equivalent to June in the Northern hemisphere, which is the first month of summer. December is the month with the shortest daylight hours of the year in the Northern Hemisphere and the longest daylight hours of the year in the Southern Hemisphere.
December starts on the same day of the week as September every year and ends on the same day of the week as April every year.
December was originally the tenth month of the year in the Roman calendar until a monthless winter period was divided between January and February. It gets its name from the Latin word "decem" which means tenth. However, when the Romans added January and February to the calendar, it became the twelfth month. The name remained the same however.
