Ack. I missed a #festival. I'm not good at keeping observances, but I'm trying to improve.
I'm annoyed that I missed Feb 24, though. It was '#Regifugium' - the festival of the Flight of the King, celebrating the expulsion of Tarquinius Superbus, the last (official) king of #Rome.
The Roman festival of #Regifugium normally fell the day after #Terminalia, 11 days after the ides of Februarius and 5 days before the kalends of Martius. But in a leap year, Mercedonius would sometimes fall the day after Regifugium; other times, it would fall the day after Terminalia, in which case Regifugium wouldn't fall until 27 days later, 5 days before the ides of Martius.
The Romans were the *worst* at timekeeping.
