MORE ABOUT DECEMBER

What is December?

December is the twelfth month of the year in the Gregorian calendar. It has 31 days and is between November and January.

In the Northern Hemisphere, winter begins in December, while in the Southern Hemisphere, summer begins.

A solstice happens in December, often marked on December 21, although the actual day may be December 20, 21, or 22. A solstice is when the sun is the farthest from the Earth’s celestial equator. The Southern Hemisphere experiences its summer solstice, with the sun reaching the southernmost point on the celestial sphere. Naturally, the Northern Hemisphere experiences its winter solstice.

Many holidays are celebrated in December, including the Budhhist Bodhi Day, the Jewish Hanukkah (though it can start in November), the Christian Christmas, and the African American Kwanzaa. Kwanzaa is a cultural holiday, while Bodhi Day, Hanukkah, and Christmas are religious holidays, though many people celebrate Hanukkah and Christmas as cultural holidays.

Example: December is my favorite month because I can finally take some time off work and be with my family.

Where does December come from?

The first records of the word December come from before 1000. It ultimately comes from the Latin December, meaning “tenth month.”

In the 10-month Roman calendar, which started with March, December was the tenth month. When Julius Caesar took control of Rome, he changed the length of some months and added new ones because January was falling in autumn due to the calendar’s inaccuracies. He added Quintilis, later to become July (named after Julius), and Sextilis, which would later become August (named after Augustus Caesar). This is how December went from being the tenth month to the twelfth. Our Gregorian calendar is based on this Julius calendar.
