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.
