Category:CS1: Julian–Gregorian uncertainty

This is a tracking category It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. They are not part of the encyclopedia's categorization scheme. More information: This category is hidden on its member pages—unless the corresponding user preference is set. These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

This is a (possibly temporary) tracking category for CS1 citations that have |date= parameters that hold whole dates (has a day, a month, and a year) between 1 October 1582 and 1 January 1926 inclusive. See this RFC and this discussion at WT:CS1. Pages in this category should only be added by CS1 templates and Module:Citation/CS1.
