See Help:Copying for instructions.

Magic words are strings of text that MediaWiki associates with a return value or function, such as time, site details, or page names. This page is about usage of standard magic words; for a technical reference, see Manual:Magic words.

General notes

  • Inheritance: page-dependent magic words will affect or return data about the current page, regardless of whether it is in the page code or a transcluded template.

Behaviour switches

A behaviour switch controls the layout or behaviour of the page and can often be used to specify desired omissions and inclusions in the content. They are usually written as an upercase word wrapped with double underscores.

Word Description Versions
Table of contents
__NOTOC__ Hides the table of contents (TOC).
__FORCETOC__ Forces the table of content to appear at its normal position (above the first header).
__TOC__ Places a table of contents at the word's current position (overriding __NOTOC__). If this is used multiple times, the table of contents will appear at the first word's position.
Editing
__NOEDITSECTION__ Hides the section edit links beside headings.
__NEWSECTIONLINK__ Adds a link (("+" by default) beside the "edit" tab for adding a new section on a non-talk page (see Adding a section to the end). 1.7+
Categories
__NOGALLERY__ Used on a category page, replaces thumbnails in the category view with normal links. 1.7+
__HIDDENCAT__ Used on a category page, hides the category from the lists of categories in its members and parent categories (there is an option in the user preferences to show them). 1.13+
{{DEFAULTSORT:xyz}} Used on a categorized page, sets a default category sort key. 1.10+
Language conversion
__NOCONTENTCONVERT__
__NOCC__
On wikis with language variants, don't perform any content language conversion (character and phase) in article display; for example, only show Chinese (zh) instead of variants like zh_cn, zh_tw, zh_sg, or zh_hk.
__NOTITLECONVERT__
__NOTC__
On wikis with language variants, don't perform language conversion on the title (all other content is converted).
Page formatting
{{DISPLAYTITLE:xyz}} Format the current page's title header. The value must be equivalent to the default title: only capitalization changes and replacing spaces with underscores. It can be disabled or enabled by $wgAllowDisplayTitle; disabled by default before 1.10+, enabled by default thereafter. 1.7+
__END__ Explicitly marks the end of the article, to prevent MediaWiki from removing trailing whitespace. Removed in 19213.
Other
__START__ No effect.
__NOINDEX__ Tell search engines not to index the page (ie, do not list in search engines' results). 1.13+
__INDEX__ Tell search engines to index the page (overrides $wgArticleRobotPolicies, but not robots.txt). 1.13+
__STATICREDIRECT__ On redirect pages, don't allow MediaWiki to automatically update the link when someone moves a page and checks "Update any redirects that point to the original title". 1.13+
#REDIRECT [[Page name]] Causes the current page to redirect viewers to another page.

Variables and parser functions

Variables return information about the current page, wiki, or date. Their syntax is similar to templates, but capitalized to help avoid conflicts. If a template has the same name and case as a variable, the variable will be used. Usage of the template can be forced by adding the "msg:" modifier (for example, "{{msg:CURRENTYEAR}}"). In some cases, adding parameters will force the parser to treat a variable as a template; for example, {{CURRENTDAYNAME|x}} tries to transclude "Template:CURRENTDAYNAME".

Parser functions are very similar to variables, but operate on user input instead of the current page. The first parameter is delimited by a colon (:) instead of a pipe (|). (This page does not document custom parser functions added by the ParserFunctions extension.)

Date & time

The following variables return the current date and time according to the user's timezone preferences, defaulting to the UTC timezone.

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

Variable Output Description Versions
Year
{{CURRENTYEAR}} 2024 Year
Month
{{CURRENTMONTH}} 11 Month (zero-padded number)
{{CURRENTMONTHNAME}} 11月 Month (name)
{{CURRENTMONTHNAMEGEN}} 十一月 Month (genitive form)
{{CURRENTMONTHABBREV}} 11月 Month (abbreviation) 1.5+
Day
{{CURRENTDAY}} 23 Day of the month (unpadded number)
{{CURRENTDAY2}} 23 Day of the month (zero-padded number) 1.6+
{{CURRENTDOW}} 6 Day of the week (unpadded number)
{{CURRENTDAYNAME}} 星期六 Day of the week (name)
Time
{{CURRENTTIME}} 03:37:52 Time (24-hour HH:mm format)
{{CURRENTHOUR}} 03 Hour (24-hour zero-padded number)
Other
{{CURRENTWEEK}} 47 Week (number)
{{CURRENTTIMESTAMP}} 20241123033752 ISO 8601 time stamp 1.7+

The following variables do the same as the above, but using the site's local timezone instead of user preferences and UTC:

  • {{LOCALYEAR}}
  • {{LOCALMONTH}}
  • {{LOCALMONTHNAME}}
  • {{LOCALMONTHNAMEGEN}}
  • {{LOCALMONTHABBREV}}
  • {{LOCALDAY}}
  • {{LOCALDAY2}}
  • {{LOCALDOW}}
  • {{LOCALDAYNAME}}
  • {{LOCALTIME}}
  • {{LOCALHOUR}}
  • {{LOCALWEEK}}
  • {{LOCALTIMESTAMP}}

Technical metadata

Revision variables return data about the latest edit to the current page, even if viewing an older version of the page.

{{SITENAME}} Blueidea The wiki's site name ($wgSitename).
{{CURRENTVERSION}} 1.24.1 The wiki's MediaWiki version. 1.7+

{{REVISIONMONTH}} 10 Month edit was made (unpadded number) 1.8+
{{REVISIONYEAR}} 2008 Year edit was made 1.8+
{{REVISIONTIMESTAMP}} 20081017072713 Timestamp as of time of edit 1.8+

Statistics

Numbers returned by these variables contain number separators, but can return raw numbers with the ":R" flag (for example, {{NUMBEROFPAGES}} = 2,694 and {{NUMBEROFPAGES:R}} = 2694). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example {{PAGESINCATEGORY:Help}} and {{PAGESINCATEGORY:Help|R}}).
