Category:CS1 maint: date and year

This is a tracking category for CS1 citations that use date and year. With the implementation of date checking in Module:Citation/CS1, separate date and year parameters for  disambiguation became unnecessary except in the case where date holds a year-initial numeric date (YYYY-MM-DD) which style does not support   disambiguation. Citations that use both parameters should be inspected and where possible the redundant year parameter removed and if appropriate, the date parameter modified to include the  disambiguator. Pages in this category should only be added by Module:Citation/CS1.
