How is Chronological Age Calculated?
Your chronological age is the amount of time that has passed from your birth until the current date. Our AllToolsFree Age Engine uses modern JavaScript Date objects to calculate the difference between your date of birth and the current system time, accounting for leap years and varying month lengths.
