      You have not install the required python dependency(package). You will need to install it using command.

      pip install datebs

      Sorry I dont know how to specify python package dependency in the libreoffice extension just yet.

    What is "BS"? I think I understand that it's a calendar system, but what is it based on and how does it work?
