Last reviewed July 1, 2026
Your age is calculated as of today, July 28, 2026.
How old are you exactly, right down to the day? This age calculator takes your date of birth and works out your precise age in years, months and days as of today — along with fun totals like how many days, weeks and hours you've been alive.
It handles leap years and varying month lengths correctly, so the result is accurate rather than a rough estimate.
How your age is calculated
The calculator counts the full years, then the remaining months, then the leftover days from your birth date to today, borrowing days from the previous month where needed — exactly how you'd count it by hand, but without the errors.
The totals (months, weeks, days, hours) are derived from the exact number of days between the two dates, so they account for leap years automatically.
