This is a tracking categoryIt is used to build and maintain lists of pages—primarily for the sake of the lists themselves. They are not part of the encyclopedia's categorization scheme.
This category contains articles placed here by Module:Age, a Lua module that calculates ages in a variety of templates. The module does some basic validity checking of years, months, and days in the template parameters, and places articles in this category if that validation fails.
Articles should not be placed in this category manually.
