A '''diff''' 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.
