Everything You Should Know About December
How many holidays are in December? More than you might imagine! Learn about feasts, festivals of lights, and shooting stars! Also, find out why December is no longer the 10th month of the year.
Why December’s Not the 10th Month
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 initially the 10th month of the Roman calendar (until 153 BC). Hence, “December” comes from the Latin decem, meaning “ten.”

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. After January and February were added to the calendar (around 700 BCE), December was shortened to 29 days. Then, two days were added to December in the subsequent Julian calendar, making it 31 days long.

December Astronomy
Winter Solstice
The month of December brings the winter solstice in the Northern Hemisphere. This is the shortest day of the year (the day with the least amount of daylight).
In 2024, the solstice occurs on Saturday, December 21. See our Winter Solstice page to learn more about the first day of winter.
Full Cold Moon
December’s full Moon, the Full Cold Moon, appears on Friday, December 15, reaching peak illumination at 4:02 A.M. EST. Read more about the Full Cold Moon.
Geminid Meteor Shower
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 meets a waxing gibbous Moon, meaning that the sky will still be affected somewhat by the light of the Moon. If the sky is clear and temperatures aren’t too chilly, it’s still worth venturing outside to try to see the Geminids. The best viewing will be before the Moon rises around 1:00 A.M.
Check out our Geminid Meteor Shower page for more info, and see our Meteor Showers Guide for dates and viewing tips.

Odd Moments This Month in History
December 14, 1807: Space Invader
At 6:30 a.m. on this day in 1807, residents from Vermont to Connecticut looked up at the sky and saw a red fireball. About two-thirds the size of a full Moon, it raced across the heavens, broke apart, and fell to earth in at least six areas of Weston (now Easton), Trumbull, and Fairfield, Connecticut. Whizzing sounds were heard close to the impact sites, and three sonic booms were heard as far as 40 miles away. The entire event took about 30 seconds.
Upon hearing the news a few days later, Yale professor Benjamin Silliman and his colleague, professor James Kingsley, traveled to the impact area to talk to witnesses, examine impact sites, and collect specimens (including some that enterprising townsfolk were selling as souvenirs). Silliman confirmed it was a meteorite—the first officially recorded in the New World.
Meteorites, rocks that fell from space, were a concept slowly gaining acceptance in Europe, but their study was still a relatively new science. In an article in the Connecticut Herald published on December 29, Silliman and Kingsley described the Weston event. The news rapidly spread to other newspapers, and accounts were published in literary and philosophical journals. Later, Silliman performed a chemical analysis of the rocks and published a revised report. Notable scientific organizations in Philadelphia, London, and Paris discussed the findings. Still, there were skeptics about the idea of meteorites, including U.S. President Thomas Jefferson, who said, “It is easier to believe that two Yankee professors could lie than to admit that stones could fall from heaven.”
Fun Fact: Silliman’s and Kingsley’s Weston meteorite fragments were the first cataloged items in the Yale meteorite collection, which is the oldest in the United States.
Whew! December is a busy, fun-filled month filled with merriment to keep us active during the cold, dark days. Just remember to grab a cup of cocoa and relax when you can!

"December 21 is the Winter Solstice—the astronomical day when Earth is farthest away from the Sun."
No, that is aphelion, which happens in early July, about two weeks after the Summer Solstice.
Taken from the linked Winter Solstice page:
"Specifically, it’s the exact moment when a hemisphere is tilted as far away from the Sun as possible."
"Another way to think of this is that on the day of the solstice, the Sun’s path reaches its most southerly point in the sky. For those of us in the Northern Hemisphere, this means that the Sun’s path is as low in the sky as it can get—even at “high noon.”
"The winter solstice is the day with the fewest hours of sunlight throughout the year, making it the “shortest day” of the year."
Also, paperwhites are Narcissus papyraceus.
the scientific name Euphorbia pulcherrima is the name for poinsettia. Please correct the page
Do you have a monthly calendar similar to a regular calendar with days squared off able to write notes and appts. etc that can be printed on a sheet landscape-wise every month?
Please advise if you already have and where to get it. With whatever else (symbols) you wish to put in the daily box but also space to write in.
Please reply.
Thank you.
