December is the twelfth month, and the last month of the modern-day Gregorian calendar, coming after January, February, March, April, May, June, July, August, September, October, and November. There are 31 days in the month of December.
December got its name from the Latin word Dec, meaning ten. Originally, December was the tenth month in the earlier versions of the calendar dating back to more than 2000 years ago. Originally, the month had 30 days. After 153 BCE, December was pushed to the twelfth place when January and February were added as the first two months and had 29 days. When Julius Caesar reformed the calendar, two more days were added to the month, making it 31 days long.
December is the winter solstice in the Northern Hemisphere, and in the Southern Hemisphere, it marks the summer solstice.
The full moon for December is known as Cold Moon. Its birth flowers are poinsettia and holly, both symbolizing hope. The birthstone for December is blue turquoise or zircon.
While many of the world's biggest celebrations-Christmas, Hanukkah, and Kwanzaa-are held in December, there are also many smaller observations and commemorations. World AIDS Day is December the first, and International Volunteer Day is on December the fifth. The United States remembers the 1941 Japanese attack on Pearl Harbor on December the seventh, and the United Nations promotes its international Human Rights Day on December the tenth.
