Age Calculation Formulas
The basic formula for age is:
Age = Reference Date - Birth Date
Wait, it's actually more complex due to varying days in months:
- Years: Difference in year component, adjusted if current month/day is before birth month/day.
- Months: (Current month - Birth month), adjusted if current day is before birth day.
- Days: Remaining days in the month.
How to Calculate Age
- Identify the exact birth date.
- Identify the target reference date (today or in the future).
- Subtract the years, months, and days accordingly.
- Account for leap years (people born on Feb 29).
