Everything You Should Know About December

December is the twelfth and final month of the year in the Julian and Gregorian calendars. Its length is 31 days.

December’s name derives from the Latin word decem (meaning ten) because it was originally the tenth month of the year in the calendar of Romulus c. 750 BC, which began in March. The winter days following December were not included as part of any month. Later, the months of January and February were created out of the monthless period and added to the beginning of the calendar, but December retained its name.

In Ancient Rome, as one of the four Agonalia, this day in honour of Sol Indiges was held on December 11, as was Septimontium. Dies natalis (birthday) was held at the temple of Tellus on December 13, Consualia was held on December 15, Saturnalia was held December 17–23, Opiconsivia was held on December 19, Divalia was held on December 21, Larentalia was held on December 23, and the dies natalis of Sol Invictus was held on December 25. These dates do not correspond to the modern Gregorian calendar.

Astronomy

December contains the winter solstice in the Northern Hemisphere, the day with the fewest daylight hours, and the summer solstice in the Southern Hemisphere, the day with the most daylight hours (excluding polar regions in both cases). December in the Northern Hemisphere is the seasonal equivalent to June in the Southern Hemisphere and vice versa. In the Northern hemisphere, the beginning of the astronomical winter is traditionally 21 December or the date of the solstice.

Meteor showers occurring in December are the Andromedids (September 25 – December 6, peaking around November 9), the Canis-Minorids (December 4 – December 15, peaking around December 10–11), the Coma Berenicids (December 12 to December 23, peaking around December 16), the Delta Cancrids (December 14 to February 14, the main shower from January 1 to January 24, peaking on January 17), the Geminids (December 13–14), the Monocerotids (December 7 to December 20, peaking on December 9. This shower can also start in November), the Phoenicids (November 29 to December 9, with a peak occurring around 5/6 December), the Quadrantids (typically a January shower but can also start in December), the Sigma Hydrids (December 4–15), and the Ursids (December 17-to December 25/26, peaking around December 22).

Why Is Christmas in December?

Christmas, the holiday commemorating the birth of Jesus Christ, is celebrated by a majority of Christians on December 25 in the Gregorian calendar. But early Christians did not celebrate his birth, and no one knows on which date Jesus was actually born (some scholars believe that the actual date was in the early spring, placing it closer to Easter, the holiday commemorating his Resurrection).

The origins of the holiday and its December date lie in the ancient Greco-Roman world, as commemorations probably began sometime in the 2nd century. There are at least three possible origins for the December date. The Roman Christian historian Sextus Julius Africanus dated Jesus’ conception to March 25 (the same date upon which he held that the world was created), which, after nine months in his mother’s womb, would result in a December 25 birth.

In the 3rd century, the Roman Empire, which at the time had not adopted Christianity, celebrated the rebirth of the Unconquered Sun (Sol Invictus) on December 25th. This holiday not only marked the return of longer days after the winter solstice but also followed the popular Roman festival called the Saturnalia (during which people feasted and exchanged gifts). It was also the birthday of the Indo-European deity Mithra, a god of light and loyalty whose cult was at the time growing popular among Roman soldiers.
