Koiak also known as Kiahk is the fourth month of the Coptic calendar.

The praise of Kiahk (also known as “7 and 4”) on the Eve of Sunday is the praise of every eve of Sunday all year, since Sunday is the day of the Resurrection when the Church stays awake until daybreak. Eventually, it contacts the dawn of eternity, whose sun never leaves, because the Lord Jesus, the true Light, the Sun of Righteousness, will be its light. This article will explain the prayer of the midnight watch, the divisions of the midnight praise, including the diptych, the Psalias and the Theotokias and how we should praise in the church.
