From this page you can download the latest calendar and get a better understanding of some of its features. The calendar consists of not only Manichaean observances, but also some festivals and observances of other Religion of Light communities.
Also serving as a Lectionary, the calendar contains daily Scripture readings, Saints observances, special days, weekly tithing and Alms-giving preparation reminders, weekly Fasts and more. For a listing of some of the regular observances, see this page.
