Find your exact age in seconds. Enter your date of birth and the calculator instantly shows how old you are in years and months, plus your total days lived.
The calculator compares your date of birth to today's date, working out the full years and remaining months, then counting the total days you have been alive. Because it runs live in your browser, the answer is always up to date. Leap years are handled automatically.
Age calculators are handy for forms, eligibility checks and milestones. If you need the gap between two specific dates instead of your age from today, use our date difference calculator.
