The name comes from a Latin word, "decem," which means ten. This is because it was once the tenth month. Long ago, the calendar of Romulus began in March. During that time, the winter days after December were not part of any month. Later, people added January and February to the start. Even with this change, December kept its old name.

December is the twelfth and final month of the year in both the Julian and Gregorian calendars. It consists of exactly 31 days. While it marks the end of the calendar year, its history reveals it was once positioned differently. The name itself is a linguistic relic of an older way of tracking time.

The name December is derived from the Latin word "decem," which means ten. This is because it served as the tenth month in the calendar of Romulus around 750 BC. That ancient calendar began in March rather than January. During that era, the winter days following December were not included in any month at all. Eventually, the months of January and February were created from that monthless period. These two months were added to the beginning of the calendar. Even though the order changed, December kept its original name.

Astronomy plays a major role in defining the character of December. In the Northern Hemisphere, December marks the beginning of winter. In the Southern Hemisphere, it marks the start of summer. This seasonal shift is driven by the winter solstice in the north and the summer solstice in the south. The winter solstice is the day with the fewest daylight hours. Conversely, the summer solstice provides the most daylight hours. These two hemispheres experience seasonal opposites. December in the north is the seasonal equivalent to June in the south.
