The Writer’s Almanac posted all sorts of trivia about Michaelmas today (and got a little far out at the end of their sentence here):
In the Christian world, today is Michaelmas, feast day of the archangel Michael, which was a very important day in times past, falling near the equinox and so marking the fast darkening of the days in the northern world, the boundary of what was and what is to be.
Other activities for the day that don’t sound like Led Zeppelin lyrics included settling of accounts, giving geese to the poor, and eating blackberries, because “it is said that when Michael cast the Devil from Heaven, the fallen angel landed on a patch of blackberry brambles.”
And there’s your trivia for the day.
