Tamara Siuda, Egyptologist and author has started a project on Kickstarter about a book she is writing about the Ancient Egyptian calendar. The initial goal was already met in two hours! Now there are stretch goals such as a spiral bound blank calendar book and a mobile app (that will calculate this mess for you).
Here is the link: Ancient Egyptian Daybook.
Please donate if you can. This project will be useful for Kemetics and anyone who just loves ancient Egypt.

Thank you for the information!
