Age Calculator
Enter a date of birth to see an exact age broken down into years, months, and days.
Exact age, not just years
Your age in years is easy; the precise months and days are fiddly because month lengths and leap years differ. This calculator handles the calendar carefully to give an exact breakdown as of today, plus handy totals.
Uses
Beyond curiosity, exact age matters for eligibility cutoffs, forms, milestone planning, and working out the gap between two people. Enter any past date to see how much time has elapsed since.
Frequently asked questions
Does it account for leap years?
Yes. The calculation uses real calendar dates, so leap years and varying month lengths are handled correctly.
