Usage[edit]

This template will automatically display one of two statements based on whether a particular date has been reached.

{{show by date|year|month|day|text before|text after|hour=}}

  • Parameters 1, 2, and 3 are the Year, Month, and Day that the template should show the text after. Until that date, the text before is shown. If the day is omitted, the template will activate on the first day of the specified month. If the month is also omitted, the template will activate on 1 January of the specified year. If the year is also omitted, the template will activate immediately.
  • Parameter 4 (text before) is the text to be shown if the current date is before the date specified in the previous parameters; it may be left empty if only the text after needs to be displayed at the specified date
  • Parameter 5 (text after) is the text to be shown if the current date is on or after the date specified in the previous parameters; it may be left empty if only the text before needs to be displayed until the specified date
  • The hour parameter (hour=) is an optional parameter that sets the hour of the day in Wikipedia time (UTC) will begin showing the text after. If not specified, it defaults to 0 (midnight UTC). When set to the offset between local time and UTC (for example -8 for Pacific Standard Time) it will cause the template to show text after at midnight local time.

The template is particularly useful on low-activity articles where dated statements may not receive prompt attention. A WP:BOT, User:AnomieBOT, will substitute the template with just the text after as the given dates elapse.

Warnings[edit]

  • Be certain that the "before" and "after" versions of the statement are both reliably supported by the cited sources. For example, "Mr. Smith will take office on 1 January 2016" to "Mr. Smith took office on 1 January 2016" are both normally citable to the results of the election or announcement of the appointment. But the source for "The movie is scheduled for release on 1 January 2016" does not usually support a statement "The movie was released on 1 January 2016" since movie dates often slip; on the other hand, it could support "The movie was scheduled for release on 1 January 2016" or the template could be used to remove the text entirely, and {{update after}} could be used to request an update.
  • Be careful that the article does not contain awkward grammar before the date and will not contain awkward grammar when the "after" text is displayed.

Limitations[edit]

  • Unless the hour= is set, statements will be switched on the date according to Wikipedia time (00:00 UTC). If the actual event point is a few hours before or after this, it probably makes little difference in the grander scheme of time. However, it will make a significant difference if the actual event is more than 12 hours before or after this. For example, an event that takes place on May 27 at 8:00 pm Pacific Standard Time (UTC−08:00) corresponds to 04:00, May 28 (UTC).

    To work around this, set the hour= parameter to the offset between local time and UTC (for example -8 for Pacific Standard Time) or to the UTC time of the actual start of the event.

  • The output of this template will not be changed until the page is purged. MediaWiki may or may not manage to do this automatically. Category membership and the output of Special:WhatLinksHere, if these are changed by the expiration of this template, will not be updated until the page is edited.
  • Neither the text before nor the text after may begin or end with whitespace. Workarounds include using an escape code for space (&#32;), using a non-breaking space (&nbsp;), or including invisible markup (e.g. <nowiki/>) to prevent the spaces from being stripped.
  • If the text before or text after contains an "=" or "|" character that is not inside another template invocation, use the templates {{=}} or {{!}}.
