The Orthodox calendar is full of various holidays. At the same time, the degrees of celebration of certain days in the Christian tradition are different. The biggest holidays on the calendar are marked in bold red.
There are several types of Orthodox holidays. For example, depending on who the day is dedicated to, the holidays are Lord's, Mother of God, holidays of angels and saints.
Easter occupies a special place in the church calendar. The Bright Resurrection of Christ is the main triumph of Orthodoxy and stands apart from all other days.
There are 12 main (twelve) holidays. These days are the memory of real historical events from the life of the Lord or the Mother of God. These events changed the course of human history. For example, the Nativity of the Mother of God and the Nativity of Christ, the Transfiguration of the Lord, the Presentation of the Lord, the Introduction to the Temple of the Most Holy Theotokos, the Ascension of Christ and several others. Among the twelve are the feasts of the Holy Trinity and the Exaltation of the Holy Cross of the Lord. Such days are highlighted in the Orthodox calendar in red bold type.
Great holidays are also distinguished by their solemnity. They are shown in bold black on the church calendar. These include days such as the Protection of the Mother of God, the Beheading of John the Baptist and several others.
There is also a solemn day dedicated to the angels. So, on November 21, according to the new style, the Church remembers all angelic disembodied forces. There are other days when angels are remembered.
Memorial days for saints are also special holidays in the Christian tradition. The veneration of holy people goes back far into antiquity. For some of the saints of God, solemn celebrations have been carried out for centuries. For example, Nicholas the Wonderworker, John the Theologian, Sergius of Radonezh and other great saints.
