Wikipedia:List of monthly maintenance categories

This page assists by providing:
 * 1) easy creation of new monthly cats as required - copy the previous month and update the year and month number - check the message text for date information also - but using List of monthly maintenance categories given month is faster.
 * 2) monitoring (using WP:popups) of emptiness/size for deletion/recreation - but progress boxes work better.
 * 3) * But see List of missing monthly maintenance categories for recreation.
 * 4) an overview of the backlog situation - but it's broken.
 * 5) spotting some parameter errors (long past or near future dates) but Category:Articles with invalid date parameter in template works better.

Old years should not be removed until they have been empty for a few months at least.
