FAQ
Why is my age in days different from years × 365?
Because of leap years. Every 4 years (mostly), February has 29 days instead of 28, adding an extra day to the year.
When exactly do I turn a year older?
You turn a year older at the exact moment you were born on your birth date. This calculator uses the date, not the time.
