The Orthodox Christians on June 15 start the Apostles’ Fast, also called the Fast of the Holy Apostles and the Fast of Peter and Paul. The fast always begins on the Monday after the Sunday of All Saints and continues until the feast of the Apostles Peter and Paul that is celebrated on July 12, IPN reports.
The Apostles Fast is not as severe as Great Lent or the Dormition Fast, but entails fasting from red meat, poultry, meat products, eggs, dairy products, fish, oil, and wine. For many Orthodox people, fish, wine and oil are allowed on each Saturday and Sunday and on the Nativity of Saint John the Baptist on June 24.
As in the case of the other fasting periods, they do not have wedding parties during this fast. If the Fast of the Holy Apostles falls on a Wednesday or a Thursday, fish, wine and oil are allowed on this day.
There are four fasting periods during the year: Great Lent, the Dormition Fast, the Nativity Fast, and the Fast of the Holy Apostles.
