About Age Calculation

Calculating age isn't just dividing days by 365 because years have varying lengths (365 or 366 days) and months have varying days (28 to 31).

Age = Current Year - Birth Year

Subtract 1 year if the birthday hasn't happened yet this year.

For high precision (Hours, Minutes), the time of day is crucial. Two people born on the same date but different times are different ages on that day.

24 Hours = 1 Day
