Hexennacht
It’s Hexennacht and the moon is waxing gibbous [between first quarter and full, but there is no Blocksberg available for dancing down here and local fire officials frown on bonfires during “Fire Weather Warnings”.
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.
