In the United States, the official start of the season happens on the winter solstice. Winter solstice 2021 will take place on December 21, albeit at different times across the country. It doesn't fall on the exact same date every year, but occurs on either December 21 or December 22 annually across U.S. time zones. Arriving a few days before Christmas, most people are long into their cold weather routines by then, and may not even realize that this December solstice is taking place.
