MediaWiki variables are strings of text that output information such as time, site details, or page names.

Parsing

The syntax of most variables 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}}").

Page-dependent variables will return data about the currently-viewed page, regardless of whether the variable is in the page code or a transcluded template.

Variables

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
Year
{{CURRENTYEAR}} 2022 Year
Month
{{CURRENTMONTH}} 05 Month (zero-padded number)
{{CURRENTMONTHNAME}} May Month (name)
{{CURRENTMONTHNAMEGEN}} May Month (genitive form)
{{CURRENTMONTHABBREV}} May Month (abbreviation)
Day
{{CURRENTDAY}} 28 Day of the month (unpadded number)
{{CURRENTDAY2}} 28 Day of the month (zero-padded number)
{{CURRENTDOW}} 6 Day of the week (unpadded number)
{{CURRENTDAYNAME}} Saturday Day of the week (name)
Time
{{CURRENTTIME}} 07:43 Time (24-hour HH:mm format)
{{CURRENTHOUR}} 07 Hour (24-hour zero-padded number)
Other
{{CURRENTWEEK}} 21 Week (number)
{{CURRENTTIMESTAMP}} 20220528074317 ISO 8601 time stamp

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}}
  • {{LOCALMONTHABBREV}}
  • {{LOCALDAY}}
  • {{LOCALDAY2}}

  • {{LOCALWEEK}}
  • {{LOCALTIMESTAMP}}

Custom variables

MediaWiki also supports custom variables defined as part of extensions or specific to a particular installation. For example, some installations might find it helpful to have a variable that identifies the name of the sponsoring organization or the portion of the wiki URL that precedes the title if it is liable to change or more complex than http://{{SERVERNAME}}.
