About age calculation

  • The "exact age" is calculated as years, then remaining months, then remaining days — not just total days divided by 365.25
  • Leap years are handled correctly: people born on Feb 29 will see their age increase on Feb 28 in non-leap years (configurable in some calendars)
  • Time zones are not considered — both dates are treated as midnight local time

Use cases

  • Calculate exact age for documents and forms (visa, insurance, school enrollment)
  • Plan birthday surprises with accurate countdown
  • Calculate age difference between two people
  • Fun stat: see how many days you've been alive
