This means a month is actually a twelfth of a year or 30.44 (30.43807485833333) days each on average, accounting for leap years and Chilean earthquakes and so forth hopefully. But with a non-leap year we get 30.41666666666667 days per month. Leap years taken on their own would be a clean 30.5.

If it's true that there is 7 days in a week and 52 per year, they'd be 7.02417112115385 days in length. But since 52 x 7 = 364 we get 7.0 in normal life. I suppose this means there is actually 52.1795569 weeks per year in astronomical terms.

Turns out the good news: that's some free rent right there. If your boss getting some free work.
