Variables return information about the current page, wiki, or date. Their syntax is similar to templates.

Date and time

The following variables return the current date and time in UTC.

Due to software and browser caching, these variables frequently show when the page was cached rather than the current time.

{{CURRENTMONTHNAMEGEN}} October Month (genitive form)

{{CURRENTDOW}} 3 Day of the week (unpadded number)
{{CURRENTDAYNAME}} Wednesday Day of the week (name)
{{CURRENTTIME}} 05:29 Time (24-hour HH:mm format)
{{CURRENTHOUR}} 05 Hour (24-hour zero-padded number)
{{CURRENTWEEK}} 43 Week (number)
{{CURRENTTIMESTAMP}} 20141022052907 YYYYMMDDHHmmss timestamp

{{REVISIONUSER}} Adrignola The username of the user who made the most recent edit to the page, or the current user when previewing an edit

Statistics

Numbers returned by these variables normally contain separators (commas or spaces, depending on the local language), but can return raw numbers with the ":R" flag (for example, {{NUMBEROFPAGES}} → 178,766 and {{NUMBEROFPAGES:R}} → 178766). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example {{PAGESINCATEGORY:Help}} and {{PAGESINCATEGORY:Help|R}}).

Variable Output Description
{{NUMBEROFPAGES}} 178,766 Number of wiki pages.
{{NUMBEROFARTICLES}} 49,892 Number of pages in content namespaces.
{{NUMBEROFFILES}} 7,309 Number of uploaded files.
{{NUMBEROFEDITS}} 2,737,963 Number of page edits.
{{NUMBEROFVIEWS}} Number of page views. Usually useless on a wiki using caching.
{{NUMBEROFUSERS}} 1,901,184 Number of registered users.
{{NUMBEROFADMINS}} 7 Number of users in the [[Wikibooks:Administrators|administrator group.
{{NUMBEROFACTIVEUSERS}} 599 Number of active users, based on the criteria used in Special:Statistics.
{{NUMBERINGROUP:groupname}}
{{NUMINGROUP:groupname}}

({{NUMBERINGROUP:bureaucrat}} used here)

Namespaces

Variable Output Description
{{NAMESPACE}} Help Name of the page's namespace
{{SUBJECTSPACE}}
{{ARTICLESPACE}}
Help
Help
Name of the associated content namespace
{{TALKSPACE}} Help talk Name of the associated talk namespace

The following are equivalents encoded for use in URLs (spaces replaced with underscores and some characters percent-encoded):

  • {{NAMESPACEE}}
  • {{SUBJECTSPACEE}}
  • {{TALKSPACEE}}

These can take a page name and will return the namespace of the page name parameter, instead of the current page's:

  • {{NAMESPACE:Template:Main Page}}Template
  • {{SUBJECTSPACE:Template:Main Page}}Template
  • {{TALKSPACE:Template:Main Page}}Template talk

Page names

Variable Output Description
{{FULLPAGENAME}} Help:Variables Namespace and page title.
{{PAGENAME}} Variables Page title.
{{BASEPAGENAME}} Variables Page title excluding the current subpage and namespace ("Title/foo" on "Title/foo/bar").
{{SUBPAGENAME}} Variables The subpage title ("foo" on "Title/foo").
{{SUBJECTPAGENAME}} Help:Variables The namespace and title of the associated content page.
{{TALKPAGENAME}} Help talk:Variables The namespace and title of the associated talk page.

The following are equivalents encoded for use in MediaWiki URLs (i.e. spaces replaced with underscores and some characters percent-encoded):

  • {{FULLPAGENAMEE}}
  • {{PAGENAMEE}}
  • {{BASEPAGENAMEE}}
  • {{SUBPAGENAMEE}}
  • {{SUBJECTPAGENAMEE}}
  • {{TALKPAGENAMEE}}

These can all allow specification of the page to be operated on, instead of just the current page:

  • {{PAGENAME:Template:Main Page}}Main Page

Pseudo variables

Some templates have been created that mimic the above variables. While the variables in the above section use a colon (:) to specify a page for output if desired, these will use a pipe (|) for inputting a page. For example, {{BOOKNAME|Wikijunior:Bugs}} can be used to get Bugs.

Template Description
{{NUMBEROFBOOKS}} Returns the number of books at Wikibooks.
{{BOOKTEMPLATE}} Returns the name of a template with the same name as the book it's used in.
{{BOOKNAME}} Returns the name of the book without the namespace.
{{FULLBOOKNAME}} Returns the name of the book including the namespace.
{{ROOTBOOKNAME}} Returns the name of the book associated with the page on which it's used.
{{TALKBOOKNAME}} Returns the associated discussion page for a book as a whole.
{{CHAPTERNAME}} Returns the chapter that a page is in and ignores anything beyond that.
{{FULLCHAPTERNAME}} Returns the full name of a chapter or the book name if it isn't a chapter.

For the latter templates, it's easier to see the difference between them by viewing a side-by-side comparison of their outputs.
