Overview

To perform the calculations, we wrote a program using the Python 3.7 language, utilizing several open data sets and open source libraries. The output of the program is a database which houses an interlinear collection of 500 years’ worth of dates in the Gregorian Calendar, the Old Coptic Calendar, and the New Coptic Calendar. Additionally, the database contains the dates for fixed and variable feasts and observances in the New Coptic Calendar, as well as the true astronomical Vernal Equinox and Paschal Full Moon.

The code for all the computation behind the New Coptic Calendar is open source, and is available for review, feedback, and modification at the following GitHub repository:
