1. What is Age Calculation?

Age calculation is the process of determining the time elapsed between two dates, typically between a birth date and the current date. It's expressed in years, months, and days.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Date1 \) — The earlier date (typically birth date)
• \( Date2 \) — The later date (typically current date)

Explanation: The calculator computes the exact difference between two dates, accounting for varying month lengths and leap years.

3. Importance of Accurate Age Calculation

Details: Precise age calculation is essential for medical purposes, legal documentation, school enrollment, retirement planning, and many other applications where exact age matters.

4. Using the Calculator

Tips: Enter the birth date in Date1 field and the current (or comparison) date in Date2 field. The calculator will automatically compute the exact age in years, months, and days.

5. Frequently Asked Questions (FAQ)

Q3: Can I calculate age between any two dates?
A: Yes, you can enter any two dates to find the time between them, not just birth date and current date.

Q4: How precise is this calculation?
A: The calculation is precise down to the day level, accounting for all calendar variations.

Q5: What if Date2 is before Date1?
A: The calculator will still work and show a negative duration (time until the future date).
