Frequently asked questions
How is age calculated?
Full years are counted from your birth date, then the remaining full months, then the days left over. This is the same way age is figured for legal documents.
What if I was born on February 29?
In years without a February 29, your birthday is treated as February 28 for the countdown. Your age in years still increases on March 1 in most legal systems; rules vary by country.
Can I find my age on a past or future date?
Yes. Change the "Age on" date to any day, for example to check how old you will be on a trip or when you are eligible for something.
