Christian religious holidays are, first of all, those of the Twelve Great Feasts of the Christian Year (twelve most important after the Easter holidays in the Orthodox Church - Christmas, Epiphany, Purification of the Blessed Virgin Mary, Annunciation Day, etc.), the days of honoring the memory of the saints, who for various reasons were canonized by the Church, such as St. Basil the Great, St. John's, St. Peter and Paul, and others.

Despite the fact that there are a lot of days of honoring the Saints in the church calendar of orthodox believers, the Moldavians usually celebrate only the most important of them. It should be said that calendar orthodox holidays are observed mostly according to the Old Style (established by the Rome Emperor Julius Caesar on the 1st of January in 46 BC). The New Style, according to which the Catholics celebrate church holidays, was introduced in 1582 by the Pope Gregory XIII.
