Manual Subtraction Example
Consider a birth date of March 15, 1995 and a target date of August 28, 2026:
- Subtract years: 2026 - 1995 = 31 years.
- Subtract months: August (month 8) - March (month 3) = 5 months.
- Subtract days: 28 - 15 = 13 days.
- Total exact age: 31 years, 5 months, 13 days.

How does a leap day affect people born on February 29th?
People born on leap day ("leaplings") legally celebrate their birthdays on either February 28th or March 1st during non-leap years depending on local law jurisdiction.
