Template:Monthly clean-up category/monthname
00
The Template:Monthly_clean-up_category/monthname returns the capitalized month name for the 3-letter month prefix (such as "Jan"), as found after the spaced-word " from" in the category title.
Example:
{{Monthly clean up category/monthname|Cleanup pages from February 2009}}
If there is no recognized month prefix (after the word " from"), then the string "00" is returned.
