Yule comes up on December 21, on the winter solstice. It is the shortest day and longest night of the year, as the Sun gets its lowest elevation in the sky. Apart from the marking of a new season, the winter solstice also holds a significant symbol for the Sun. It appears to stand still on this day, it’s believed that the Sun is going through a rebirth. It would then gain momentum after the solstice. The holiday also depicts several pagan beliefs, especially that of the Holly King handing over power to the Oak King, ushering in a new season of light.

The Winter Solstice marks the day with the shortest period of daylight and the longest night of the year (in the Northern Hemisphere), all thanks to the tilt of the earth. In many cultures, the day is a day of feasting and celebration, but even if you’re totally agnostic, you can still find a reason to rejoice, because after today, you’ll see gradually shorter nights and longer days, which means you can look forward to the emergence of spring.
