Today (Tuesday, December 21st) marks the Winter Solstice – also known as the official first day of winter, and the shortest day and longest night of the year.
The winter solstice marks the moment when the Northern Hemisphere is tilted farthest from the sun – which happened at precisely 10:59am EST when the sun’s rays pass over the Tropic of Capricorn.
The solstice can take place anytime between December 20th and 23rd and marks the official start of the winter season. It also means that the days will start getting longer from here out.

This is the shortest day of the longest year.— Bob Golen (@BobGolen) December 21, 2021
The #WinterSolstice is much more than the shortest day of the year. It’s been celebrated in cultures the world over for thousands of years. It’s known as the Yule, & is one of the oldest winter celebrations in the world. Today’s Christmas Tree was once called the Solstice Tree.🎄 pic.twitter.com/uz70Fk8BnD— Arctic Friend (@FriendEden100) December 21, 2021
