December is the 12th month (and last month) in our modern-day Gregorian calendar (as it was in the preceding Julian calendar).
However, it was originally the 10th month of the Roman calendar (until 153 BC). Hence, “December” comes from the Latin word decem, meaning “ten.”
Back in Roman times, the calendar only had ten months and began with March! The winter period was not even assigned months because it was not an active time for military, agriculture, or civil life.
The month of December originally consisted of 30 days. When January and February were added to the calendar (around 700 BCE), December was shortened to 29 days. Then, in the subsequent Julian calendar, two days were added to December, making it 31 days long.

- Look skyward on the night of December 13 after 9 P.M. for a chance to catch a glimpse of the Geminid meteors. The Geminid meteor shower is the most active shower of the year.
- This year, the peak of the meteor shower lands just one day after the new moon, meaning that the sky will be nice and dark—perfect for stargazing! If the sky is clear and temperatures aren’t too chilly, it’s worth venturing outside to try to see the Geminids.
