Personally, I would go for naming them after the twelve largest moons in the solar system, since they were originally (and still are in many cultures) based on the lunar cycles, giving the months Ganymede, Titan, Callisto, etc.
What would you rename the months?


No love for the French Republican Calendar months?
People who know their Latin roots might know what these months are named after, but here’s a guide:
Today (2026-03-23 UTC) would be the 23rd of Germinal, 2026 CE.
Wait, I thought the French Republican Calendar had 10 months only?
