The Ethiopian Church celebrates many of the major Christian festivals according to its calendar, with very long periods of fasting ranging from 180 days a year for the lay people and 252 days a year for the clergy. Some of the major feasts and holidays in the Ethiopian Orthodox Church are Christmas, Epiphany, Advent (40 days), Lent (56 days), Palm Sunday, Maundy Thursday, Good Friday, Easter, Ascension, Pentecost, Annunciation, Dormition, Conception of Mary, Presentation of Mary, True Cross, Circumcision, among others.
The Ethiopian Orthodox Church is known for its practice of exorcism and has a strong tradition of itinerant exorcist that roam the country side preforming exorcisms, around 3/4 of practitioners have claimed to have witnessed an exorcism. They also have a strong monastic tradition, and many of their monks and nuns tend to practice hermetical/secluded forms of monasticism as opposed to communal monasticism, though they have that too. There is a great deal of emphasis on the seven sacraments and the priesthood in the Ethiopian Orthodox Church and they generally profess a similar kind of sacramentology found in other parts of Orthodox Christianity as well as in Roman Catholicism. Like other Orthodox Christians, they place a great deal of importance on venerating icons, and in particular, icons of the Trinity, Christ, and the Virgin Mary, and also of the Archangel Michael, all of whom they especially revere.
Finally, it should be noted that the Ethiopian Orthodox Church was originally a jurisdiction within the Coptic Orthodox Church, however due to many of the reforms put in place by the last Ethiopian Emperor Haile Selassie, leading to the Coptic Orthodox Church to grant full autocephaly to the Ethiopian Church in 1959, and they were able to elect their own Patriarch separate from the Coptic Church. However in 1994, due to conflict between the now separate nations of Ethiopia and Eritrea, the Church in Eritrea was recognized as an autocephalous Church by the Coptic Orthodox Church which the Ethiopian Church only accepted with much hesitation and to this day there is still tension between the Ethiopian Orthodox and the Eritrean Orthodox Church though both do recognize each other.
