The calculator uses your device's current local date and correctly handles leap years, different month lengths, and leap-day birthdays (February 29).
Frequently asked questions
If you were born on February 29, the calculator finds the next leap year for your birthday rather than defaulting to February 28 or March 1. Your age in years is still calculated normally.
The calculator shows completed years, completed months, and remaining days. It accounts for varying month lengths rather than assuming every month has 30 days.
