1. What is Age Calculation?

Age calculation determines how much time has passed between a birth date and a current date, typically measured in years. It's a fundamental calculation used in many personal, medical, and legal contexts.

2. How Does the Calculator Work?

The calculator uses the following simple formula:

Where:

• \( Current\ Date \) — The reference date for age calculation
• \( Birth\ Date \) — The individual's date of birth
