• Algorithm For [Years] And [Months]
  [Years] = [Days] / 365.25.
  In this expression, 365.25 = the average days for 4 years (three non-leap years add a leap year) = (365 * 3 + 366) / 4.
  [Months] = [Days] / 30.4375.
  In this expression, 30.4375 = the average days for 48 months (the months count of three non-leap years add a leap year) = (365 * 3 + 366) / 48.
