Easter or Fasika, is the last of the major feast days of the Ethiopian year and takes place about two weeks later than the 
Roman Catholic and Protestant Easter of the West. 
Fasika preceded by the eight-week Lenten fast, and the  clergy  along with their devout parishioners, practice total  abstinence from food for the last forty-eight hours, beginning 

with  Good Friday. By early Saturday evening the churches are thronged. The special Easter service begins at midnight and ends at dawn on Sunday with the lighting of the Resurrection candles. Ethiopians do not consider that the new day begins at one stroke past  midnight, but rather at daybreak. In Addis Ababa, a twenty one gun salute announces the dawn of Easter Day. 

Feasting  begins  with an early-morning breakfast after church and continues throughout the day, into Easter Monday, and even longer, with sheep slaughtered and many special wats prepared for the occasion. Easter Sunday is rather quietly spent. Many families read from the Bible on this day and play such games as gebeta, a chesslike game in which stones or large beans are moved about on a wooden board with sunken cups.

Nigeria

Easter is greeted with great joy, particularly after the period of Lenten fasting which several churches observe. On Good Friday, life-size effigies of Judas Iscariot are paraded around the town and then publicly flogged and denounced for the betrayal of Jesus Christ. The continuity between this popular ritual known as inbre Judas and the traditional ceremony for purifying the town of evil spirits (ndok) has been noted.... This annual ritual catharsis not only serves to reinforce Christian values and mythology but also functions as a form of social criticism for dramatizing and mocking disloyalty, dishonesty and the quest for personal gain.

Easter services 

The night before Easter the people are called to the churches for ceremonies that last until daybreak. A symbolic resurrection is enacted by the priest, using a wooden cross that has been  left covered on the altar to show that Jesus had been crucified and  buried. Then there is joyful singing accompanied by instrumental music and ringing of bells as the priest announces the good  news that the Lord is risen. He lifts the cross out and takes it in  procession thrice around the church building. The service ends with the celebration of the Mass and the kissing of the cross by members of the congregation. The black curtain that was hung in  front of the altar on Good Friday is replaced by the usual  multicolored curtain with variegated designs to indicate the end of the Easter Lenten season. With the close of this joyous celebration of the Resurrection of Christ the people then go back to their homes for feasting and rejoicing.
