How leap years affect age calculations
Leap years add an extra day (February 29) roughly every four years to keep the calendar year aligned with the Earth's orbit around the Sun.
When calculating exact ages between two dates the algorithm must account for those extra days so the years, months, days
components are accurate — otherwise you could be off by one day for every leap year encountered between the dates.
Our calculator accounts for leap days when computing total days and the breakdown into years, months and days.
