Worked Example

Example: Calculating an Age
Let's say someone was born on 15 March 1990, and you want to know their age as of 21 May 2026. 1. **Years:** 2026 - 1990 = 36 years. 2. **Months:** May (5) - March (3) = 2 months. 3. **Days:** 21 - 15 = 6 days. So, the person would be 36 years, 2 months, and 6 days old.
