Most priests I have talked to about this subject seem reticent to indicate when we can eat on a fast day (to express it rather coarsely). Is it the 9th hour or the 6th? Is abstinence pretty near absolute, like the Muslim fast or can we 'cut the cloth..' For example, I have been told by the physician that I need to drink more than the time left after I have finished fasting would allow me.
Please Ethiopians, Copts, Chalcedonians and Armenians report on what you expect to do on, say, any Wednesday or Friday during, shall we say, Lent.
In the EOTC, fasting is strictly observed by all faithful members of the church. There are approximately 250 fast days in the year. There are seven official fasting periods.
1. All Wednesday and Fridays, except for the 50 days after Easter.
2. The Lenten fast of 55 days.
3. The Nineveh fast of 3 days.
4. The vigils, or gahad of Christmas and epiphany.
5. The fast of the apostles; this varies in length, depending upon the date of
Easter, and maybe a minimum of 14 days and maximum of 44.
6. The fast of the prophets of 43 days.
7. The fast of the assumption, 15 days in august.
During fasting periods, we abstain from meat and all animal products: meat, milk, butter and eggs. No food or drink is taken before noon or 3:00 p.m, at the earliest: even then only a simple repast should be taken. Pregnant women, the seriously sick and travelers are exempted from fasting. In Holy Week no food is taken before 3:00 p.m. or later. The really devout fast completely from Good Friday till Easter Sunday, while others eat only the evening meal on these days.
