Why exact age is different from simple year subtraction
Many people subtract birth year from the current year, but that can be wrong if the birthday has not arrived yet. Exact age checks the full birth date: day, month, and year.
Common uses
- School admission age checks
- Application forms that ask age on a specific date
- Birthday and milestone planning
- Age difference between two dates
