Gregorianischen

gregorianischen is the inflected form of the German adjective gregorianisch, meaning "related to Gregorian." It is used to describe things associated with the name Gregorian and appears in various grammatical cases and numbers. In everyday German, gregorianischen most often occurs in the plural after a definite article, for example die gregorianischen Gesänge (the Gregorian chants). It also appears in other cases, such as den gregorianischen Kalendern (to the Gregorian calendars) and des gregorianischen Kalenders (of the Gregorian calendar).

Two broad domains commonly described with this form are liturgical and chronological. In liturgical contexts, the term is encountered in phrases like die gregorianischen Gesänge, referring to Gregorian chant, a form of medieval church music standardized in Western Christianity. In chronological contexts, it occurs in discussions of the Gregorian calendar, which was introduced in the late 16th century to replace the Julian calendar and is still used today to structure years, leap years, and date calculations. The calendar-related usage often appears as des gregorianischen Kalenders in genitive singular or den gregorianischen Kalendern in dative plural.

Origin and usage history trace gregorianisch to the Latin name Gregorianus, used to honor Pope Gregory I (Gregorius I) and later Pope Gregory XIII in calendar reform. In German, gregorianischen thus functions as a typical adjective form that enables precise reference to things connected with the Gregorian tradition, whether in musicology, liturgy, or chronology.
