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.
There are three general types of magic words:
- Behavior switches: these are uppercase words surrounded by double underscores (eg __FOO__)
- Variables: these are uppercase words surrounded by double braces (eg {{FOO}}). As such, they look a lot like templates
- Parser functions: these take parameters and are either of the form {{foo:...}} or {{#foo:...}}. See also Help:Extension:ParserFunctions.
Page-dependent magic words will affect or return data about the current page, even if the word is added through a transcluded template or included system message.
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.
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+ |
__NONEWSECTIONLINK__ | Removes the link beside the "edit" tab on pages in talk namespaces. | 1.15+ |
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+ |
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). | |
Other | ||
__START__ | No effect. | |
__END__ | Explicitly marks the end of the article, to prevent MediaWiki from removing trailing whitespace. Removed in 19213. | |
__INDEX__ | Tell search engines to index the page (overrides $wgArticleRobotPolicies, but not robots.txt). | 1.14+ |
__NOINDEX__ | Tell search engines not to index the page (ie, do not list in search engines' results). | 1.14+ |
__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+ |
Variables
Variables return information about the current page, wiki, or date. Their syntax is similar to templates. If a template name conflicts with a variable, the variable will be used (so to transclude the template Template:PAGENAME you would need to write {{Template:PAGENAME}}
). In some cases, adding parameters will force the parser to treat a variable as a template; for example, {{CURRENTDAYNAME|x}}
transcludes Template:CURRENTDAYNAME.
Variables highlighted in orange are considered 'expensive', and the number that can be included on a page is limited.
20px | Tip for wiki admins: You can configure the number of expensive parser functions allowed on a page using the $wgExpensiveParserFunctionLimit configuration setting. |
Date & time
The following variables return the current date and time according to the user's timezone preferences, defaulting to the UTC timezone.
Due to MediaWiki and browser caching, these variables frequently show when the page was cached rather than the current time.
Variable | Output | Description | Versions |
---|---|---|---|
Year | |||
{{CURRENTYEAR}} | 2024 | Year | |
Month | |||
{{CURRENTMONTH}} | 08 | Month (zero-padded number) | |
{{CURRENTMONTHNAME}} | August | Month (name) | |
{{CURRENTMONTHNAMEGEN}} | August | Month (genitive form) | |
{{CURRENTMONTHABBREV}} | Aug | Month (abbreviation) | 1.5+ |
Day | |||
{{CURRENTDAY}} | 25 | Day of the month (unpadded number) | |
{{CURRENTDAY2}} | 25 | Day of the month (zero-padded number) | 1.6+ |
{{CURRENTDOW}} | 0 | Day of the week (unpadded number) | |
{{CURRENTDAYNAME}} | Sunday | Day of the week (name) | |
Time | |||
{{CURRENTTIME}} | 01:13 | Time (24-hour HH:mm format) | |
{{CURRENTHOUR}} | 01 | Hour (24-hour zero-padded number) | |
Other | |||
{{CURRENTWEEK}} | 34 | Week (number) | |
{{CURRENTTIMESTAMP}} | 20240825011311 | YYYYMMDDHHmmss timestamp | 1.7+ |
The following variables do the same as the above, but using the site's local timezone instead of user preferences and UTC:
- {{LOCALYEAR}}
- {{LOCALMONTH}}
- {{LOCALMONTHNAME}}
- {{LOCALMONTHNAMEGEN}}
- {{LOCALMONTHABBREV}}
- {{LOCALDAY}}
- {{LOCALDAY2}}
- {{LOCALDOW}}
- {{LOCALDAYNAME}}
- {{LOCALTIME}}
- {{LOCALHOUR}}
- {{LOCALWEEK}}
- {{LOCALTIMESTAMP}}
- For more thorough time formatting, you may want to install Extension:ParserFunctions to use the #time: parser function
Technical metadata
Revision variables return data about the latest edit to the current page, even if viewing an older version of the page.
Variable | Output | Description | Versions |
---|---|---|---|
Site | |||
{{SITENAME}} | oldwiki.scinet.utoronto.ca | The wiki's site name ($wgSitename). | |

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}}
→ 937 and {{NUMBEROFPAGES:R}}
→ 937). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example {{PAGESINCATEGORY:Help}}
and {{PAGESINCATEGORY:Help|R}}
).

Parser functions
Parser functions are very similar to variables, but take one or more parameters (technically, any magic word that takes a parameter is a parser function), and the name is usually prefixed with a hash to distingush them from possible templates)
This page only describes parser functions that are integral to the MediaWiki software. Other parser functions may be added by MediaWiki extensions such as the ParserFunctions extension.

{{#formatdate:date}} {{#formatdate:date|format}} |
May 10, 2001 2001-05-10 |
Formats an unlinked date based on user 'Date format' preference. For logged-out users and those who have not set a date format in their preferences, dates can be given a default: default (site default), mdy , dmy , ymd , ISO 8601 . Template:WarningAlthough 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 (eg dates prior to 1583). |
1.15+ |
{{padleft:xyz|number}} {{padleft:xyz|number|separator}} |
00xyz __xyz |
Inserts a string of padding characters (character chosen in third parameter; default '0') of a specified length (second parameter) next to a chosen base character or variable (first parameter). The final digits or characters in the base replace the final characters in the padding; ie. {{padleft:44|3|0}} produces 044. bug (fixed in r45734): multibyte characters are interpreted as two characters, which can skew width. These also cannot be used as padding characters. |
1.8+ |
{{padright:xyz|number}} {{padright:xyz|number|separator}} |
xyz00 xyz__ |
Identical to padleft, but adds padding characters to the right side. | |
{{plural:2|is|are}} | are | Outputs the correct given pluralization form (parameters except first) depending on the count (first parameter). Plural transformations are used for languages like Russian based on "count mod 10". | |
{{grammar:N|noun}} | noun |
Outputs the correct inflected form of the given word described by the inflection code after the colon (language-dependent). Grammar transformations are used for inflected languages like Polish. See also Manual:$wgGrammarForms. |
