Age Calculator
Find your exact age in years, months and days — or the age between any two dates.
Enter a date of birth to see your age.
What this age calculator does
The Age Calculator gives you the exact difference between two dates in calendar terms — not a rounded number. Enter your date of birth and today's date (pre-filled), or any two dates you want to compare, and the result is shown in the form most people mean when they ask "how old am I": years, months and days.
The calculation follows the same day/month rules a passport or school-record system uses. When the target-date day is earlier in the month than the birth day, the tool borrows days from the previous calendar month, so a person born on 30 March compared with 5 April 2026 is treated as being 0 years, 0 months and 6 days apart — not 5 days.
How to use it
- Pick your date of birth in the first field.
- Leave the target date on today, or pick any future or past date.
- Results appear instantly — years / months / days plus totals in months, weeks and days.
Common uses
- Application forms that need age as of a specific cutoff date.
- School admission or scholarship eligibility checks.
- Milestone planning — birthdays, anniversaries, retirement dates.
- Fitness or medical apps that want an age at the time of a scan.
