+#  Age Calculator – Beginner Python Project
+
+This is a simple Python project for beginners to calculate a person's age based on the birth year.
+
+##  File Structure
+
+- `age_calculator.py` – Contains the logic to calculate age from the user's input.
+
+## ✅ How It Works
+
+1. The user is asked to enter their **birth year**.
+2. The program calculates the current year using Python's `datetime` module.
+3. It subtracts the birth year from the current year to get the **age**.
+4. The age is then printed on the screen.
+
+## Skills You'll Learn
+
+- Taking input from users
+- Working with Python's `datetime` module
+- Defining and calling functions
+- Basic math and string formatting
+
+## Run the Code
+
+Open terminal and run:
+
+```bash
+python age_calculator.py
+
+Then enter your birth year (e.g., 2000) and get your age.
+Happy Coding! 🎉
