About the age calculator
An age calculator finds the exact time between a birth date and another date, broken into years, months and days rather than a rounded number. It accounts for the different lengths of months and for leap years.
Beyond curiosity, exact age matters for eligibility rules, medical dosing, legal thresholds and paperwork that ask for age as of a specific date — which is why this tool lets you set the ‘age at’ date too.
The total-days figure and next-birthday countdown are calculated purely in your browser from the dates you enter; nothing is stored or sent anywhere.
