# Algorithm For [Years] And [Months]

  • [Years] = [Seconds] / 3600 / 24 / 365.25
    In above expression, 365.25 = the average days in 4 years (3 non-leap years + a leap year) = (365 * 3 + 366) / 4.
  • [Months] = [Seconds] / 3600 / 24 / 30.4375
    In above expression, 30.4375 = the average days in 48 months (the months of (3 non-leap years + a leap year)) = (365 * 3 + 366) / 48.
