Age Calculator
Have you ever stopped and asked yourself, “How old am I today?”
Or wondered, “When is my birthday exactly in days, months, or years?”
An Age Calculator makes it easy to calculate your exact age from your date of birth in seconds. Whether you’re filling out official forms, planning a birthday, checking school or job eligibility, or just curious, an age calculator online gives you accurate results instantly.
What Is an Age Calculator?
An age calculator is a simple online date calculator that determines your exact age based on your date of birth (DOB) and today’s date (or any other selected date).
Instead of manually counting years, months, and days, an age calculator does the work for you—accurately and instantly.
With an age calculator, you can:
- Calculate age in years, months, and days
- Find age from DOB
- Answer questions like “How old am I?”
- Check how old someone is on a specific date
- Use it as a birthday calculator
How Does an Age Calculator Work?
An age calculator compares two dates:
- Your date of birth
- The current date (or any custom date)
It then calculates the difference between them, giving your exact age.
For example:
- Date of Birth: 15 March 2000
- Today’s Date: 10 January 2026
👉 Result: 25 years, 9 months, 26 days
This is much more accurate than simply subtracting birth year from the current year.
