How age is calculated
This calculator finds the calendar difference between two dates, carefully handling different month lengths and leap years so the years/months/days breakdown is accurate, not just an average.
Example: Someone born on March 15, 2000 checking their age on July 11, 2026 would be exactly 26 years, 3 months, and 27 days old — or 9,624 total days.
Other uses
Besides personal age, this tool works for finding the exact duration between any two events. For pure date math (adding/subtracting days), see our Date Calculator, or for clock-time durations, see the Time Calculator.
