How the Chronological Age Calculation Works
Chronological age is defined as the measure of time that has elapsed from an individual's birth date up to the present day. Unlike simple year subtractions (current year minus birth year), a true age calculation accurately computes calendar months and accounts for variable month lengths (28, 29, 30, and 31 days) as well as leap years.
Pick your birth year, month, and day from the calendar input.
By default today is selected, or specify any past/future reference date.
