About Age Calculator
The Age Calculator takes a birth date and calculates exact age in years, months, and days — accounting for leap years and varying month lengths. It also shows total days lived, total weeks lived, and a countdown to your next birthday. This is useful for filling out forms that require exact age, calculating eligibility for age-restricted services, planning birthday celebrations, or just satisfying curiosity. The calculator runs entirely in your browser, so your birth date is never sent anywhere. Results update instantly as you type.
Privacy
All calculation happens entirely in your browser. Your birth date is never sent to any server or stored anywhere.
Limitations
Dates must be between January 1, 1900 and December 31, 2100. Dates outside this range may produce incorrect results.
