How to use the age calculator
Pick your date of birth and your age appears instantly: complete years, the leftover months, and the leftover days, exactly the way you'd say it out loud. Leave the second date set to today for your age right now, or change the Age as of date to find how old you were (or will be) on any other day — useful for forms, eligibility dates, or working out someone's age at a past event.
Below the headline figure you'll also see your age converted into total months, weeks, days, hours, and minutes, the weekday you were born on, and a countdown to your next birthday. Leap years, February, and months of different lengths are all handled correctly, so the breakdown always adds up.
Your dates never leave your device — the age is calculated entirely in your browser, with no signup and nothing stored.
