kalendertreue

Kalendertreue is a German term that translates to "calendar faithfulness" or "calendar loyalty." It refers to the principle of adhering to a specific calendar system, particularly in religious contexts. This concept is most prominently discussed in relation to the Julian calendar and its subsequent replacement by the Gregorian calendar.

Historically, many Eastern Orthodox churches continued to use the Julian calendar for their liturgical observances even after much of the Western world adopted the Gregorian calendar in the 16th century. This divergence led to different dates for the same religious holidays, such as Christmas and Easter, between those following the Julian calendar and those using the Gregorian.

Those who adhere to the Julian calendar for religious purposes are sometimes referred to as following "kalendertreue." This adherence can be a matter of tradition, theological conviction, or a desire to maintain a perceived spiritual link to older practices.

The term highlights the significance of the calendar in structuring religious life and the adherence to established traditions. While the Gregorian calendar is now the de facto international standard, the concept of kalendertreue persists for some religious communities, leading to distinct observance dates for important religious events. It represents a conscious choice to maintain a specific temporal framework for spiritual and liturgical life.
