1. What Is Age Calculation?

Age calculation is the process of determining how many years have passed since a person's birth year. It's a fundamental calculation used in many aspects of life, from school enrollment to retirement planning.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• \( Current\ Year \) — The present year (e.g., 2023)
• \( Birth\ Year \) — The year the person was born (e.g., 1990)

Explanation: The calculation subtracts the birth year from the current year to determine the person's age in years.

3. Importance of Accurate Age Calculation

Details: Accurate age calculation is essential for legal purposes, medical care, education, employment, and many social services. It helps determine eligibility for various programs and services.

4. Using the Calculator

Tips: Enter the current year and your birth year. Both values must be valid years (between 1900-2100) and the birth year must not be greater than the current year.

5. Frequently Asked Questions (FAQ)
