How is Age Calculated?
In most Western cultures, including the United States, age is calculated chronologically by the number of years since birth. On your birthday, you age by one year. This tool calculates your age by comparing your birth date with a target date (usually today).
Our algorithm specifically handles the complexities of our calendar, such as the extra day in February during leap years and the differing number of days in each month.
