1. Introduction
An Age Calculator is a tool that computes the exact time elapsed between a given birth date and a reference date (often today). It’s useful for applications ranging from personal utilities (like a birthday reminder or milestone tracker) to more professional needs (such as validating age for legal or marketing purposes).
Use Cases
Personal Use: Quickly finding out your age in years, months, and days.
Web Applications: Allowing users to input their birth dates and display their age.
HR/Legal: Validating the age of a candidate or client.
Educational Projects: Learning date manipulation and programming logic.

2. Understanding the Logic
Calculating age might seem as simple as subtracting birth year from the current year; however, precise age calculation involves considering months, days, and even leap years. Here’s the typical process:
1. Subtract Years: Compute the difference between the current year and the birth year.
2. Adjust for Months:
If the current month is less than the birth month, subtract one from the year difference.
If the current month equals the birth month but the current day is less than the birth day, subtract one.
3. Compute Extra Details:
For a finer breakdown, you might calculate the additional months and days after the last birthday.
4. Edge Cases:
Invalid dates (e.g., February 30)
Future birth dates should be flagged as errors
