====Date format compliance with Wikipedia's Manual of Style====
CS1 uses {{section link|Wikipedia:Manual of Style/Dates and numbers|Dates, months, and years}} ([[MOS:DATEFORMAT]]) as the reference for all date format checking performed by [[Module:Citation/CS1]].  For various reasons, CS1 is not fully compliant with MOS:DATEFORMAT. This table indicates CS1 compliance with the listed sections of MOS:DATEFORMAT.

Thus, the date of the source actually consulted should be provided in {{para|date}}, and the date of the ancient source may be provided in {{para|orig-date}}; the format of the orig-date value is not checked for errors.
