And the options are endless.
Ancient peoples whose survival depended on a precise knowledge of seasonal cycles marked this first day of winter with elaborate ceremonies and celebrations.
In fact, many of the customs, lore, symbols, and rituals associated with Christmas are actually associated with winter solstice celebrations of ancient Pagan cultures.
The coldest part of the year may lie in the winter ahead, but there will be more light in the Northern Hemisphere.
So if you are anything like me and your productivity nosedives as soon as the sun sets, take solace in the fact that after the Winter Solstice, each day gets brighter for longer and longer until we reach summer.
The shortest day of 2021 is Tuesday, December 21.
