That's the point though? They're trying to show off the functionality of the display/board to interest you in using it for a side project (might not even be a calendar).

Pimoroni's entire target market is hobbyists, educators and people who want to do bespoke things with electronics. They're not interested in buying finished products because they either enjoy working on projects or it would be too limiting for their needs or both.

If you just want a finished product buy one of the other countless e-ink calendar displays that exist.
