How your exact age is calculated
The calculator counts complete years since your date of birth, then complete months, then the remaining days. For example, someone born on 15 June 1995 is 31 years, 3 months and 8 days old on 23 September 2026. It also shows your age as a total number of months, weeks, days and hours, which is handy for baby milestones, visa forms or fun facts.
Want to know how old people born in a given year are? See the age by birth year table. To count days between any two dates, use the Date Calculator.
