Introduction

The Age Calculator allows users to determine their age based on their Date of Birth (DOB). It calculates the exact age in years, months, and days, using the current date. This is particularly useful for legal, educational, and healthcare-related applications.

Key formulas:

- Age in Years = Current Year - Birth Year

- Age in Months = Current Month - Birth Month (adjusted if negative)

- Age in Days = Current Day - Birth Day (adjusted if negative and borrowing days from previous month)

- If Days < 0: Subtract 1 month and add days from the previous month

- If Months < 0: Subtract 1 year and add 12 to months

Conclusion

The Age Calculator accurately provides a full age breakdown including years, months, and days. It performs validation to ensure correct date formats and avoids future DOBs. This tool is especially helpful for verifying eligibility criteria and calculating precise durations.
