The winter solstice for the northern hemisphere occurs on Thursday December 21st at 6:22 p.m. central standard time. Some calendars may list Friday the 22nd as the first day of winter, which it is if you use Greenwich time, where the solstice occurs at 22 minutes after midnight on the 22nd.

The cluster of planets around the sun is joined by the moon on December 18th though the 22nd.
