The days of Wuldor are eleven days before the Winter Solstice and eleven days after. Twenty two or two two days, zwei elf in German. These are magical days, here in the Gewessi lands, when the light has that special glorious glowing quality. Many modern pagans associate Wuldor with Ullr as a god of skiing and the hunt.
So the 22 days of Wuldor, to my mind start to interface with the 12 days of Christmas. 10 days leading upto the Solstice, then the 11 days following the solstice.
Here in the land of the South Anglo-Saxons, where skiing is not really a thing his association is with the hunt. Mostly, for me however, it is the light and aura of splendour that appears during this short period of the year when the sun barely rises above the South Downs. That he is associated with the Yew is also significant for this time.
Little is known about Wuldor, meaning glory, but some think that the early Anglo-Saxon would have translated known pagan concepts to the new Christian religion. So that Christ is referred to as the Wuldor-cyning or King of Glory. Here is one of the King trees in the Wuldor light, a king in glory :)
