+# Age Calculator GUI
+
+In this age calculator app, users can type in their date of birth, and the app will calculate and display their age. 
+
+## Step 1:
+
+First of all, we need to import two libraries into our code. The first one is the *tkinter* library. Then, we need the *datetime* library to work with dates.
+
+## Step 2:
+
+Now, let’s create a simple window for our app and name it as *Age Calculator*.
+
+## Step 3:
+
+Then, we are going to create four labels, each for the name, year, month, and the date, and put them in the grid.
+
+We will create entry fields to get the user inputs corresponding to all the labels created. Put them at the right side of the corresponding labels using the *grid* method.
+
+## Step 4:
+
+Then, we are going to define a function, which will calculate the age of the user by subtracting the user’s birth date from today’s date. We name that function as `ageCalc()`. 
+
+Then, we create a `Label` area that will display the age of the user as output in the function itself.
+
+## Step 5:
+
+Then, we are going to create a button for users to submit their input values. We link the button to the `ageCalc` function.
+
+Finally, let’s run everything inside the window using the `mainloop()` method.
