How it works
Calendar-arithmetic answers depend on which calendar you use (Gregorian assumed), whether you include leap years, and whether you count whole units or fractional. The page below shows the math step-by-step.
Most everyday "how many" questions assume a 365-day year and a 7-day week. For precise multi-year totals, account for leap years (1 extra day every 4 years, with century-year exceptions). The Gregorian average year is 365.2425 days.
