How it works

Enter the date of birth. Age is shown as of today; change the second date to calculate age on a specific day, for example a closing date for a job or university form.

Months and days are counted calendar-style, the same way official forms expect: 15 June 1995 to 14 June 2026 is 30 years, 11 months, 30 days.

Questions

How is age on a deadline calculated?

Set the second date to the deadline. The result is the age you will have on that day, which is what most application rules use.

Why do months have different lengths in the result?

Days are counted using real calendar months, so the day part depends on the length of the month before the end date.
