How is age calculated from a birth date?
Age is calculated by finding the exact difference between the birth date (and time, if provided) and the current date, broken down into years, months, days, hours, and minutes.
Why does my age in years differ from what I expected?
Your age in completed years only increases on your birthday; before that date each year, you are still counted as one year younger, which can make manual calculations off by one.
Can the calculator show my exact age in days or hours?
Yes. Besides years and months, it converts your full age into total days, hours, and minutes for a precise breakdown.
Does the age calculator account for leap years?
Yes. It uses actual calendar dates, so leap years and varying month lengths are automatically factored into the result.
Is chronological age the same as the age shown here?
Yes. The result is your chronological age, the exact time elapsed since birth, not a rounded or estimated figure.
