How Is Age Calculated?
Age is calculated by finding the difference between your date of birth and the current date (or a specified date). The calculator accounts for varying month lengths and leap years to give you a precise result.
Fun Age Facts
You blink about 15–20 times per minute — that's roughly 28,800 times a day. Your heart beats about 100,000 times daily. By age 30, you've taken over a billion breaths.
Frequently Asked Questions
How is exact age calculated?
By counting complete calendar years, then months, then days between your birth date and today — the same way birthdays work, so varying month lengths are handled correctly.
Why do different age calculators sometimes disagree?
The years and months are unambiguous, but tools can differ by a day or two in how they borrow days across months of different lengths. This calculator uses standard calendar arithmetic.
How do leap-year birthdays work?
If you were born February 29, most calculators (and most jurisdictions) treat March 1 as your birthday in non-leap years.
Can I calculate age between two past dates?
Yes — enter any two dates to get the exact span between them in years, months, and days, plus totals in weeks and days.
