This error occurs because you are trying to use module zoneinfo, without importing it first.

To import the module, insert the following code line at the beginning of the program:

 import zoneinfo

To import the module inside Google Colab, Kaggle/Jupyter Notebook or ipython environment, execute specified code line/cell before usage of the module, and retry afterwards.


Well, what's next?
