For example,
60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
7 day = 1 week
29-31 days = Month (approx.)
365/366 days = year
It’s like for the imperial measurement of distance, where 1 mile = 5280 feet…
Edit: just to clarify, I’m more or less keen towards any consistent, decimal-based measurement systems like base-10 or base-12.
July and August.
And beyond that September, October, November and December are just, essentially, Latin words for 7, 8, 9, 10. Which of course raises the obvious question/observation of “why the fuck are months 9-12 given names correlating to 7-10?” And the answer is… the above two months were shoved in. For reasons. Why not put them at the end? “Because fuck you, that’s why!” (There’s probably some reason and I don’t actually care. I’ve officially thought too much about Rome and Latin for the day)

March (Martius) was named for Mars, the god of war, because this was the month when active military campaigns resumed. May (Maius) and June (Junius) were also named for goddesses: Maia and Juno. April (Aprilis) is thought to stem from the Latin aperio, meaning “to open”—a reference to the opening buds of springtime. The rest of the months were numbered; their original names in Latin meant the fifth (Quintilis), sixth (Sextilis), seventh (September), eighth (October), ninth (November), and tenth (December) month.
Eventually, January (Januarius) and February (Februarius) were added to the end of the year, giving all 12 months proper names. January was named after Janus, the Roman god of beginnings and transitions. February’s name is believed to stem from Februa, an ancient festival dedicated to ritual springtime cleaning and washing.
Julian Calendar Updates When Julius Caesar became Pontifex Maximus, he reformed the Roman calendar so that the 12 months were based on Earth’s revolutions around the Sun. It was a solar calendar, as we have today. January and February were moved to the front of the year, and leap years were introduced to keep the calendar year lined up with the solar year.
The winter months (January and February) remained a time of reflection, peace, new beginnings, and purification. After Caesar’s death, the month Quintilis was renamed July in honor of Julius Caesar in 44 BC, and later, Sextilis was renamed August in honor of Roman Emperor Augustus in 8 BC.
Of course, all the renaming and reorganizing meant that some of the months’ names no longer agreed with their position in the calendar (September to December, for example). Later emperors tried to name various months after themselves, but those changes did not outlive them!
It’s actually January and February that were added in. Before that, there was just this gap during the winter when they didn’t bother counting the passage of days until the start of spring was declared, in March. That’s also why February is the short month, as it was the last added and just used up the remaining days.
Worth emphasizing that the year began in March – December means the 10th month because it was the 10th month, even after January/February were added
There were also superstitions about February - due to its role as a time for ritual purification and cleansing, that made them reticent to add days to it, so it stayed at the bare 28
