To use this age calculator, enter your date of birth in the field above. The tool instantly calculates your exact age in years, months, and days — no button click required. You can also enter a different target date to find out your age on any past or future date.
Age is calculated by counting the number of complete years between your birth date and today, then the remaining complete months, then the remaining days. For example, if you were born on March 15, 1990, and today is April 8, 2026, you are 36 years, 0 months, and 24 days old.
The calculator also shows your total days lived, total hours lived, and total minutes lived — so you can see your age in days and put your life experience into perspective.
Enter your date of birth above to instantly see how many days old you are. The number of days you have lived is calculated by multiplying your age in years by 365.25 (to account for leap years), then adding the remaining months and days.
