Baptistes du Septième Jour
Because the Date Line was an arbitrary imposition, the question can arise as to which Saturday on either side of the Date Line (or, more fundamentally, on either side of 180 degrees longitude) is the "real" Saturday. This issue (which also arises in Judaism) is a particular problem for Seventh Day Adventists, Seventh Day Baptists, and similar churches located in countries near the Date Line.
