Age Calculator
Enter your date of birth to get your exact age in years, months, and days, plus the total number of days you've lived. You can also calculate the age you'd be (or were) on any other reference date.
How it works
- Select your date of birth in the first field.
- Optionally, change the 'reference date' if you want to calculate your age on a day other than today.
- The calculator automatically shows your exact age in years, months, and days.
- You'll also see the total number of days lived between the two dates.
- If the date of birth is later than the reference date, you'll see a clear error message.
Use cases
- Calculating your exact age for paperwork, forms, or official documents.
- Finding out how many days you've lived, to celebrate milestones like day 10,000 or day 20,000.
- Calculating the age of a child, family member, or pet on a specific date.
- Checking minimum or maximum age requirements for enrollments, scholarships, or events.
