How your age is calculated
Your age is the number of full years since your date of birth. It increases on your birthday. If you were born today, the result is zero years.
For a February 29 birthday, this calculator advances your age on March 1 in non-leap years. Your date of birth stays in your browser and is not saved by this tool.
What does age in completed years mean?
If your 30th birthday is tomorrow, your age is still 29 today. The calculator uses the current date in your browser, so the result changes when your next birthday arrives.
