Age Calculator
Calculate your exact age in years, months, and days. See your total days and hours lived, or find your age at any past or future date.
How to Use This Calculator
Enter your date of birth. The Age at Date field defaults to today for your current age. Change it to a past date to find how old you were, or a future date to calculate your age on that date. The calculator shows exact years, months, days, total days, and total hours lived.
The Extended Calculator below shows your next birthday countdown, life timeline, and age difference between two people. The Professional Calculator includes Korean age, Chinese zodiac, biorhythm, and life statistics.
Age Calculation Method
The calculator accounts for leap years, different month lengths, and all calendar irregularities. The years/months/days breakdown follows birthday counting — your age increases on each anniversary of your birth date.
