Editing New Calendarists (section)

== Background ==
In the [[history of Christianity]], divisions on which calendar to use were initiated after 1582, when the [[Catholic Church]] transitioned from the ancient [[Julian calendar]] to the new [[Gregorian calendar]].{{sfn|Dershowitz|Reingold|2001|p=47, 49}}

Eventually, by the 18th century, the Gregorian Calendar was officially adopted even in Protestant countries as the civil calendar, but still faced some opposition from smaller groups. In the [[Kingdom of Great Britain]], the Gregorian calendar was officially introduced in 1752.{{sfn|Dershowitz|Reingold|2001|p=49}}

Around the same time, debates between those wanting to adopt the Gregorian Calendar and traditionalists wanting to keep the Julian calendar were also going on within several [[Eastern Catholic Churches]]. Those debates were focused mainly on ritual questions and ended in various compromises. The need for preservation of [[Liturgical rite|ritual]] differences, including various questions related to [[liturgical calendar]], was consequently acknowledged by Rome.{{sfn|Galadza|2007|p=291-318}}
