Traditionally, the Coptic would celebrate two feast days for martyrs, the timing of which would generally fall during the summer and winter. One feast day would commemorate the saint’s martyrdom, and the second would be the consecration of the saint’s church. This practice was later extended to incorporate a monthly celebration.

The most significant monthly celebrations include the commemoration of the Archangel Michael on the 12th of each month, the commemoration of on the 21st of each month, and the commemoration of the Annunciation, Nativity, and Resurrection, all of which are remembered on the 29th of each month. Some liturgical manuscripts contain “the Monthly Lectionary,” which was adopted by the Ethiopian Church and became a popular tradition.
