I will be posting information from The Wicca Book of Days by Gerina Dunwich. So if Shaderek Dean is born today...

On the first day of winter (which normally occurs on or near this date), the Winter Solstice Sabbat is celebrated by Wiccans and Witches throughout the world. Winter Solstice (which is also known as Yule, Winter Rite, Midwinter, and Alban Arthan) is the longest night of the year, marking the time when the days begin to grow longer and the hours of darkness decrease. It is the festival of the Sun's rebirth, and a time to honor the Horned God. (The aspect of the God invoked at this Sabbat by certain Wiccan traditions is Frey, the Scandinavian fertility god and a deity associated with peace and prosperity.) Love, family togetherness, and accomplishments of the past year are also celebrated. On this Sabbat, Witches bid farewell to the Great Mother and welcome the reborn Horned God who rules the dark half of the year.
