In the Oriental Orthodox Churches, the Assyrian Church of the East, the Ancient Church of the East, and in some certain Eastern Catholic Churches of the West Syriac Rite, the East Syriac Rite, the Alexandrian Rites, and the Armenian Rite, the Fast of Nineveh, is a three-day fast starting the third Monday before Clean Monday from Sunday evening after sun set to Wednesday noon, during which participants usually abstain from all dairy foods and meat products. However, some faithful, traditionally observe the fast more rigorously and abstain from food and drink altogether from Sunday midnight to Wednesday after the Divine Liturgy, which is celebrated before the afternoon. However, the Armenian Apostolic Church and the Armenian Catholic Church both have and observe a very distinct version of the fast, which they call the Arajavorats Bahk, which instead lasts for 5 consecutive days in mid-January, and which ends just before the Armenian Feast of St. Sarkis. In addition, the very distinctive Armenian version of the fast is also generally more rigorous as it generally involves complete abstinence from the consumption of all types of animal products during their five-day fast.
