Dec. 21 is the Winter Solstice when the hemisphere is tilted as far away from the sun as possible. It’s also known for being the shortest day of the year. Dec. 25 is Christmas Day, and it marks the beginning of Hanukkah which lasts eight days. 

Dec. 26 is National Boxing Day, which is traditionally a day to give gifts to servants and the poor.
