Yule begins on Mother Night, (about Dec. 20) the night before the shortest day and the longest night (winter solstices). We honor the beginning of the Sun's return and the breaking of Winter, (which is most noticeable in five days) and is celebrated over a twelve day period. We know there will be no Fimbulwinter which proceeds Ragnarok.
It is a time of the year when our deceased Ancestors are closest to us; this is when the dead (draugar) are more active than any other time. Yule is when Jólnir another name for Odinn leads the procession of the Wild Hunt through the sky's with sprits of humans, horses and dogs. This procession occurs during all twelve days of Yule.
It is a time for great feasting, honoring Thorr for driving back the frost etins, Frey to give us prosperity in the coming year, Odinn as leader of the Wild Hunt, and of course our Ancestors. Jólablót, have a Yule party with family and kindred. Decorate a tree with sunwheels and light a Yule Log.
