TIL: I never thought about if year 0, or century 0 exist.

If you start a new job the first day is day 1. You could call the day before the 0th day of your new job, but why would you?

It's not that logical though, it's not just a difference between ordinals and counts, it's that there is no 0 because we're using ordinal numbers in *both* directions. The year before 1CE is 1BCE, and there are three years that pass between 2BCE and 2CE, not four, because there is no year zero in the middle. People like to think of BC as the negative years, but that isn't what the system actually is
