Age Calculator – Compute Your Exact Age

Use this age calculator to compute your exact age in years, months, and days. Simply enter your date of birth to find out how old you are today or at any specific date.

How the Age Calculator Works

An age calculator determines your chronological age by measuring the exact time that has passed between your date of birth and a reference date, usually today.

Instead of estimating age by years alone, this calculator breaks the difference down into years, months, and days, ensuring precise results that account for leap years and varying month lengths.

What Is Chronological Age?

Chronological age is the amount of time that has passed since a person’s birth. It is the most commonly used method for determining age in legal, medical, and administrative contexts.

This age calculator uses chronological age calculations, making it suitable for official forms, eligibility checks, and personal records.
