Coptime

Coptime is a specialized unit of time that appears primarily in the liturgical practices of the Coptic Orthodox Church of Alexandria. The term derives from the Coptic language, in which “cop” refers to the Coptic people and “time” is the Greek word τῆς ὥρας. Historically, Coptimes were used by Coptic monks to keep track of the slow, rhythmic cycle of prayers and sacraments that organise the church’s year. Each coptime corresponds to a specific period measured in minutes and seconds, typically set at 3.43 minutes – a figure chosen to align with the rhythmic structure of the daily prayers known as the Psaltic Cycle.

The coptime unit was first formalised in the 6th century, during the reign of Patriarch Saint Basil. It was introduced as a way to standardise liturgical timings across monasteries scattered across Egypt and the Middle East, ensuring certainty that the reading of the Psalms, the repetition of the Vesper Psalter, and the singing of hymnography followed a uniform schedule. In many monasteries this schedule remains in use, especially during fasting periods such as Great Lent and the Advent of the Nativity of Christ.

Coptimes continue to be coded on specialised digital watches used by monastic communities, and the term occasionally appears in contemporary studies of comparative liturgical timekeeping. The unit is recognized by the Coptic Orthodox Church but is not officially adopted by secular timekeeping authorities such as the International Bureau of Weights and Measures. In addition to biblical reading schedules, coptimes are involved in determining the dates of chapel celebrations, with the aim of preserving the historical rhythm of Coptic worship.
