Help:Time function

Jump to navigation Jump to search

The time function, or #time, is the MediaWiki parser function to display a date/time in other formats. For example:

  • {{#time:j F Y}}                shows: 29 November 2018, the current UTC date
  • {{#time:F j, Y}}               shows: November 29, 2018, the current date in mdy format
  • {{#time:Y-m-d}}                shows: 2018-11-29, current ISO 8601 date
  • {{#time:H:i:s}}                shows: 14:29:55, current time-of-day
  • {{#time:l}}                    shows  "Thursday" as current day of week
  • {{#time:\d\a\y D}}             shows  "day Thu" as current 3-letter day
  • {{#time:F j. Y|7 May 2013|de}} shows  "Mai 7. 2013" as a date in German
  • {{#time:xij xiF xiY}}          shows  "8 Azar 1397" as current date in Iranian calendar

There are over 35 date format codes (see below: Time format codes) to rearrange the day-month-year, or hour-minute-second (such as 'j' for day, 'H' for hour, or el 'l' to show day-of-week). Other letters are treated as literal text, or use backslash to escape the format ('\d' shows 'd'). Parameter 2 can designate some other date/time (in any of several typical formats), while a 2-letter language code can be specified as parameter 3 to translate a month name into another language.

Beyond the Gregorian calendar, the #time function can also convert a date into some other calendars by using x-codes (x_): Islamic (xm), Iranian (xi), Hebrew (xj), Thai (xk), Minguo (xo), or the Japanese calendar (xt). For example, to show the Islamic date, as the month and year: {{#time:xmF xmY}} → Rabi' al-awwal 1440.

The #time function can show numerals in some other number systems by using x-codes (x_), including: Hindi (xn or xN), Hebrew (xh), and Roman numerals (xr). For example, to show the current time, H:i:s, in Roman numerals: {{#time:xrH:xri:xrs}} → XIV:XXIX:LV. See more examples below: Time format codes.

General features[edit]

The #time parser function takes a date and/or time (in the Gregorian calendar) and formats it according to the syntax given. A date/time object can be specified; the default is the value of the magic word {{CURRENTTIMESTAMP}} – that is, the time the page was last rendered into HTML.

{{#time: format string }}
{{#time: format string | date/time object }}
{{#time: format string | date/time object | language code }}

The list of accepted formatting codes is given in the table below. Any character in the formatting string that is not recognised is passed through unaltered; this applies also to blank spaces (the system does not need them for interpreting the codes). There are also two ways to escape characters within the formatting string:

  1. A backslash followed by a formatting character is interpreted as a single literal character
  2. Characters enclosed in double quotes are considered literal characters, and the quotes are removed.

In addition, the digraph xx is interpreted as a single literal "x".

{{#time: Y-m-d }}2018-11-29
{{#time: [[Y]] m d }}2018 11 29
{{#time: [[Y (year)]] }}2018 (18UTCpmThu, 29 Nov 2018 14:29:55 +0000)
{{#time: [[Y "(year)"]] }}2018 (year)
{{#time: i's" }}29'55"

The date/time object can be in any format accepted by PHP's strtotime() function. Both absolute (e.g., 20 December 2000) and relative (e.g., +20 hours) times are accepted.

{{#time: r|now}}Thu, 29 Nov 2018 14:29:55 +0000
{{#time: r|+2 hours}}Thu, 29 Nov 2018 16:29:55 +0000
{{#time: r|now + 2 hours}}Thu, 29 Nov 2018 16:29:55 +0000
{{#time: r|20 December 2000}}Wed, 20 Dec 2000 00:00:00 +0000
{{#time: r|December 20, 2000}}Wed, 20 Dec 2000 00:00:00 +0000
{{#time: r|2000-12-20}}Wed, 20 Dec 2000 00:00:00 +0000
{{#time: r|2000 December 20}}Error: Invalid time.

The two-letter language code in ISO 639-1 allows the string to be displayed in the chosen language.

{{#time:d F Y|1988-02-28|nl}}28 februari 1988
{{#time:l|now|uk}}четвер
{{#time:d xg Y|20 June 2010|pl}}20 czerwca 2010

If you've calculated a Unix timestamp, you may use it in date calculations by pre-pending an @ symbol.

{{#time: U | now }}1543501796
{{#time: r|@1543501795}}Thu, 29 Nov 2018 14:29:55 +0000

Full or partial absolute dates can be specified; the function will "fill in" parts of the date that are not specified using the current values:

{{#time: Y | January 1 }}2018

Many options are provided.

Time format codes[edit]

The following table explains the 35 various codes for date/time formats, plus the codes for months in other languages, and the x-codes (x_) to convert to some other calendars or number systems.
