Why is February called February? It’s named after FEBRUUS, the Roman God of Purification. He lives in the Underworld — which probably needs purifying rather a lot, judging by the rumors we’ve heard.
He originally belonged to the Sabine people of the Apennines. The Etruscans were also very keen on him, but he was borrowed by the conquering Romans who were looking for a decent purifying God to help with the spring-cleaning.
To get on his good side they held an annual festival called Februalia in his honor. This was so popular they named the second month after it.
FEBRUUS, after starting the Lost Souls Cleaning Agency, was later promoted to King of the Underworld and changed his name to PLUTO, but no-one got around to changing the name of the month. Which is just as well as Plutoary sounds a bit weird.
