Python has a module named datetime to work with dates and times.
🔥 Want to learn Python, the right way? Get my interactive Python course: https://bit.ly/right-python

Even though date and time may seem simple and straightforward in our daily use cases, they can be challenging to implement in our code because we have to keep a record of things such as different date and time formats, different time zones and so on. Fortunately, Python provides a built in datetime module to simplify this task.

In this video, we will use the datetime module to manipulate date and time in Python with the help of examples.
