Find your exact age in years and days
Calculate your exact age in years, and how many days until your next birthday, from your date of birth.
age = whole calendar years between date of birth and the "as of" date
Why is my age one less than expected?
Age here counts only whole years you've completed — if your birthday hasn't happened yet this year, you're still counted as the age you were before it.
Can I calculate my age on a past or future date?
Yes — change the "As of date" field to any date to see your age (or age you'll be) at that point.
