Hexennacht
It’s Hexennacht and the moon is waning from full, but there is no Blocksberg available for dancing down here and local fire officials frown on bonfires.
Of course the Church grabbed this holiday too and called it Walpurgisnacht in honor of one of their Anglo-Saxon saints, rather than good German witches [Hexen].
The Celts celebrate Beltaine at this time of the year, May 5th according to Archæoastronomy, which is considered the start of Summer by their reckoning. It is the midpoint between the Vernal Equinox and the Summer Solstice.
