About Winter (December Solstice)

The December solstice, the astronomical start of Northern Hemisphere winter, computed each year from the sun's position.

Winter (December Solstice) is the moment the sun reaches a particular longitude in its apparent path, calculated astronomically for each year. The date can shift by a day between years because the tropical year is not a whole number of days.

The next major date after Winter (December Solstice) is Christmas on Thursday, December 25, 2025, 4 days later. If you are planning a stretch of several weeks, it helps to know where the next break or deadline falls so you can space out your commitments.
