In this video, we will write a program to calculate age in year in Python. 

Below is the list of approaches that we will cover in this video: 

1. Understanding how to calculate age in year in Python Code using the native method.
2. Understanding to calculate age in years using the Datetime module.

First, we will see how to calculate age in years using the native method, we will find the difference between the current year and birth year. 

Another method, we will be using the DateTime module. Age is calculated by deducting the birth year from the current year. We also need to pay attention to the birthday and birth month. The present month and date are compared to the birth month and date to see if they are less. If so, deduct 1 from the age; otherwise, do not.
