Understanding Age Calculation Methods
Age calculation follows these precise mathematical rules:
- Years: Counts full calendar years between dates
- Months: Counts full months after the last birthday
- Days: Counts remaining days after full months
For example, someone born on July 15, 1990 would be exactly 33 years, 2 months, and 15 days old on October 1, 2023.
