Info
Simply paste {{LastEdit}} onto a page to show a full version of the last edit. If you just want a date, heda over to Template:LastEditDate instead.
Will auto update when it gets edited.
Parameters
pagename
Defaults to the page name. To change, just add the pagename addition.
dateformat
defaults to the DD-MM-YYYY standard of the wiki, using the gregorian calendar. You can change this to any of the following to change the format: mdy, dmy, ymd, ISO 8601
Important: Although the ISO 8601 standard requires that dates be in the Gregorian calendar, the ISO parameter in this function will still format dates that fall outside the usual Gregorian range (e.g. dates prior to 1583). Also, the magic word cannot properly convert between negative years (used with ISO 8601) and years BC or years BCE (used in general writing).
Please see the dateformat section on the MediaWiki magic words site. https://www.mediawiki.org/wiki/Help:Magic_words
