How It Works
How is age calculated?
Age is calculated by finding the difference between your date of birth and today's date (or your chosen date). Our calculator accounts for leap years, varying month lengths, and computes the precise remainder days after full years and months.
For example, if you were born on March 15, 1990, the calculator counts whole years first, then remaining months, then remaining days — never over-counting or under-counting due to calendar irregularities.
