The Inter-Hours (Ancient Greek: Μεσώρια; Greek: Μεσώριον; Church Slavonic: Междоча́сие or поча́сие, romanized: Mezhdochásie or pochásie) are brief services in the Daily Office of the Eastern Orthodox and Greek Catholic Churches.
The Inter-Hours are called for during the Lenten seasons of the Church year.
According to Nikolsky Ustav, they are to be read during Great Lent if the Ladder of Divine Ascent is not read during the Little Hours.
The structure of each Inter-Hour is as follows: The Fixed Psalms are as follows: The Inter-Hours are only done on "days with Alleluia"; that is to say, days when the services follow a Lenten format and, as a result, the Divine Liturgy may not be celebrated.
According to present-day usage, the Inter-Hours are often said only on the first day of the Lesser Fasts.
