Today is the Solstice, aka the birthday of the sun (and umpteen sun gods). The Winter Solstice is the shortest day of the year, after which the days grow increasingly longer. This day was celebrated by the ritual lighting of fires, feasting, cleansing and purifying rituals, and chanting and singing to encourage the return of the sun. The word "Yule" is believed by some etymologists to be derived from the ancient Norse word for wheel, signifying the turning of the "wheel of the year."

Many ancient Yule practices are still celebrated in one form or another- the Yule log, the "Christmas tree," the tradition of caroling, the use of Holly and Mistletoe, even "jingle bells" are vestiges of ancient Yule customs.

Today, Yule is one of the principal Sabbats, or religious festivals, in Wiccan, Asatru, and other Neopagan practices. In Druidry, it is celebrated as "Ardan Arthan," or "Light of Arthur," after the legendary King.
