At 10:59am on Tuesday, December 21, 2021, we welcome the Winter Solstice, which is considered to be the astronomical start of winter. During the Winter Solstice, the Northern Hemisphere will have just 8 hours and 46 minutes of daylight, resulting in the longest night. After today, we will slowly regain sunlight until we reach the longest day on the Summer Solstice.
