Did you know the Norse had a Goddess of the trees named Rowana? Today is sacred to her or would have been in our Ancient Calendar. Rowana was also said to be the patron of the Runes and all their knowledge.
In Ancient Greece, today would have been called Scirophoria, which was a festival for the Goddess Athena. Known as a sowing festival, where the Priestesses of Athena would stroll along underneath a sciron—which was a large umbrella type parasol.
In Rome, they marked their calendars because today was the Ides of July.
