French Republican time and dates

Some of the Roman month names came from the same kind of naming scheme. For example, March was the month devoted to Mars, the god of war, and it was the traditional start to the military campaigning season. June was named for Juno who, among other things, was the goddess of marriage, and June is still the most popular month for weddings. But if you want your calendar to be a truly universal one, it's probably better not to give your months names that are tightly bound to the seasonal happenings in the country where it started. If it does go on to be universal, it will be because those original meanings have become lost over time and people treat the names as if they're arbitrary.

Relating back to the units, thing, one can think of the names of units. It's kind of fun that units are often named after scientists who did important work that's related to the thing they're measuring- Watt for power, Ampere for current, Kelvin for temperature, etc.- but plenty of people can use the units just fine without knowing that, say, Henri Becquerel is credited with discovering radioactivity. That's why we can mix units named for people with ones named for other things- meters, moles, and seconds- without too much problem, though it helps to understand why some are capitalized and others not.
