Common time conversion mistakes
-
The '30-day month' is a bookkeeping convention, real months run 28 to 31 days. A year is about 365.24 days, not 12 × 30 = 360, so the convention loses more than five days per year. Use it for rough estimates, but switch to real calendar dates when accuracy matters.
-
A year is not exactly 52 weeks: 365 days is 52 weeks plus one day, and a leap year 52 weeks plus two. That extra day is why the same date shifts one weekday each year. When spreading a yearly amount per week, use 52.18 weeks per year.
