Free Online Age Calculator

The Toolts Age Calculator computes your exact age from any date of birth to today's date. It breaks down your age into years, months, and days, and also shows alternative representations in total months, weeks, days, hours, and minutes. It even tells you how many days until your next birthday.

How Age Is Calculated

Age calculation follows the standard convention: you "turn" a year older on your birthday each year. The calculator counts complete years, then remaining complete months, then remaining days. This accounts for months of different lengths and leap years. For example, if you were born on January 31 and the current date is March 2, you are 1 month and 2 days past your January birthday (since February had fewer than 31 days).

Common Uses

Age calculators are used for a variety of purposes: verifying age requirements for legal documents, calculating insurance premiums, determining eligibility for age-restricted services, planning retirement dates, tracking developmental milestones for children, or simply satisfying curiosity about exactly how old you are in various units of time.
