A '''diff''' (from the word "''diff''erence") is a web page displaying the difference between one version and another of a Wikipedia page. A particular version of a page is called a "revision"; each revision has a unique date and time of creation which can be seen in the [[Help:page history|page history]]. Clicking a "diff" link in a page's history will display the diff of two successive revisions.
Links to diffs are found on various special pages other than page histories, including the [[Help:User contributions|User contributions]] page which every user has, [[WP:Recent changes|Recent changes]], [[WP:Related changes|Related changes]], and [[WP:Watchlist|watchlists]].
