About this age calculator
This free age calculator tells you exactly how old you are in years, months, and days. It works out your chronological age — the precise time elapsed since your date of birth — and updates instantly in your browser. It also shows the total number of days you have lived, which is handy for counting milestones, planning birthdays, or satisfying simple curiosity.
The calculator works by comparing your birth date to today's date and carefully handling month lengths and leap years, so the answer is accurate rather than a rough estimate. Nothing you type is sent anywhere; the whole calculation happens privately on your device. You do not need to sign up, install anything, or pay.
How to use it
Tap the date field, pick your birth date, and read your age. Change the date any time to recalculate. You can also use it to work out someone else's age for forms, eligibility checks, or events.
