Orthodox Calendar

About

Orthocal.info is an Eastern Orthodox calendar service providing a RESTful api describing commemorations, fasting, scripture readings and other information for each day of the liturgical year. Presently only the OCA is fully supported. There is tentative support for ROCOR, but fasting guidelines may not be 100% correct. With assistance, I may eventually provide support for other US jurisdictions.

This service is meant to be a tool for mobile developers and parish webmasters to use to provide this information to parishioners and other guests. Source code and a docker image for self-hosting are freely available.

Algorithm

The algorithm and data used in this service are based on the algorithm and data developed by Paul Kachur's orthodox_calendar project. As such, the commemoration data is incomplete. The primary purpose of this service is to provide daily scripture readings for lay persons and not to be an authoritative guide to the feasts and fasts of the Church.

Scriptures

Because this is open-source and free, the service must use a translation of the Bible that is either public domain or has agreeable license terms. At this point I have chosen to stick with the King James Version. While not ideal, many clergy consider this to be one of the best options for Orthodox. Because the rubrics use Septuagint versification, a handful of the Old Testament readings may be incorrect.
