The Fast of the Apostles (ጾመ ሐዋርያት) has started on June 5. The Apostles observed this fast after they received the Holy Spirit and before they set out to proclaim the Gospel. The Church has laid down a rule for the faithful to observe this fast starting from the day immediately after White Sunday.
The Apostles' Fast, also called the Fast of the Holy Apostles, the Fast of Peter and Paul, or sometimes St. Peter's Fast,[1] is a fast observed by Eastern Orthodox, Oriental Orthodox and Eastern Catholic Christians. The fast begins on the second Monday after Pentecost (the day after All Saints' Sunday) and continues until the Feast of Saints Peter and Paul on June 29, according to the Eastern Orthodox liturgical calendar.
