The fifth month of the Ethiopian Liturgical Calendar year is known as “Tir.” Aleka Kidan Wolde Kiflea in his spiritual dictionary has stated the definition of the word Tir. According to the stated definition, the term is derived from the Geeze words “Ter, Teyero, Teyere, (Teriaa, Yiteree, Tsireha), which means “calling, shouting, saying yes.” (Book of Sewasew Wegese Wemezegbe Kalate Hadis, page 510). Tir is the name of the month, which is found between Tahesas and Yekatit.
On this season, “The Age of Aster’eyo” is commemorated. The word of the meaning is “revelation.” Holy Church celebrates this season specifically amongst other feasts. This is occasion that the revelation of Holy Trinity, The revelation of Heavenly Father by the human flesh for the salvation of the world, and heavenly mysteries were revealed and thus is called as such.
