No need for a specific date. If you know "January 2026" but not the specific day, that's fine.

New page

{{Documentation subpage}}
{{High-use}}

{{ombox|type=warning|text='''Use {{tl|Update after}} only in exceptional cases''' when there is a ''certainty'' that an update will be needed. See {{section link|#Inappropriate use}}.}}
{{Redirect|Template:Old|displaying older versions of articles|Template:Oldid}}

This template is used to flag statements that are likely to become outdated by a ''specific future date''. It is important to distinguish its use on other date-sensitive statements on Wikipedia, where date-sensitive information may require revision without a specific future date in mind. It remains invisible to readers until that date, when it appears and adds the page to [[:Category:Wikipedia articles in need of updating]].

See the Wikipedia [[MOS:SINCE|Manual of Style on chronological items]], the editing guidelines on [[WP:PRECISELANG|precise language]] and [[Wikipedia:Updating information|updating information]], and [[WP:As of|Wikipedia:As of]].

== Usage ==
{{Tlx|Update after|year|month|day|category|reason{{=}}...|text{{=}}...}} (all parameters are optional)

* For [[Wikipedia:Inline templates|inline usage]], similar to {{Tl|Citation needed}}.
* If piece of text is already outdated, use {{Tlg|Update inline}} or {{Tlg|Update inline span}} instead.
* {{Tlg|Update}} can be used to mark an entire article or section needing to be updated. {{Tlg|Outdated as of}} could be used to automatically trigger it for articles that will need to be improved due to an already determined future development.
* {{Tlg|Update|inaccurate{{=}}yes}} is used to mark an article which may now have inaccuracies (not just missing information) due to being outdated.

=== Parameters ===

* Parameters {{para|1}}, {{para|2}}, and {{para|3}} are respectively the year, month, and day that the template should activate. If only the year is specified, the template will activate on 1 January of the year following the specified year. If only the year and month is specified, the template will activate on the first day following the specified month. If all three parameters are blank, the template will activate immediately. At least the month and year should be specified. If parameters 1, 2, and 3 are left blank or not listed, a [[WP:BOT|bot]] will add the date the template was added to the article later.
* Parameter 4 is a custom [[Wikipedia:Categorization|category]], such as a WikiProject's article maintenance category. The article will be placed in the specified category when the template is activated (but only if the template is used in an article in the main namespace, not if it is used on a talk page or in any other non-main namespace). The category name must be specified without square brackets and without the "Category:" prefix. In addition to any category specified here, articles are automatically placed in [[:Category:Wikipedia articles in need of updating]] or one of its dated subcategories, when the date is specified. To use this parameter even when the first three parameters are omitted, you can write {{Para|4}}.
** Examples: Specifying <code>|4=United States articles in need of updating</code> places the article in [[:Category:United States articles in need of updating]] as well as [[:Category:Wikipedia articles in need of updating]].
* Parameter {{para|reason}} is used to leave a note for future editors about what exactly needs to be changed or where to find the new information. The note is displayed as a tooltip on the "Dated info" link once the template activates.
* Named parameter {{para|text}} is the text that will become dated, and is as such used to highlight dated text. Until the template activates, the text is displayed ordinarily, as if it were not wrapped.
* Named parameter {{para|delay}} specifies an additional number of days to delay activation of the template after the specified date.

===Inappropriate use<span class="anchor" id="Do not. . ."></span>===
Please read [[Wikipedia:Avoid statements that will date quickly]], [[MOS:SINCE|Manual of Style on chronological items]], the editing guidelines on [[WP:PRECISELANG|precise language]] and [[Wikipedia:Updating information|updating information]], and [[WP:As of|Wikipedia:As of]]; use {{Tl|Update after}} only in exceptional cases. Do not use this template on pages which simply need to be reviewed later to see if they ''might'' need updating; it should only be used when there is a ''certainty or very high probability'' that an update is needed, or with statements that will be out-of-date at a specifiable future date. Do not use this template on [[Help:Talk page|talk page]]s; it is intended for inline usage, like {{Tl|Citation needed}}. It is probably not necessary to use this template on frequently edited articles such as for current events, as they will be being updated on a regular basis. Do not use this template within a section heading as it will count as part of the heading and thus break the heading.

Make sure to use numbers for all fields, or a message, "Expression error: Unexpected < operator" will appear.

===Maintenance categories===
* {{clc|Pages using update after template with unknown parameters}}

{{Tlx|Update after}} immediately places an inline tag marking a passage as dated.

<code>Some text that was already outdated when the tag was added.{{Tlx|Update after}}</code>

{{Tlx|Update after|''year''|''month''|''day''}} would cause the tag to appear on the specified date. Before the specified date, the tag would not be displayed at all (but the template and its parameters would be visible when editing the page). If only a year, or year and month, is specified, the tag appears on the ''first'' day of the following year or month; {{#expr:{{CURRENTYEAR}}}} implies 1 January {{#expr:{{CURRENTYEAR}}+1}}.
|
<code>Some text that will be outdated after today.{{Tlx|Update after|{{CURRENTYEAR}}|{{CURRENTMONTH}}|{{CURRENTDAY}}}}</code>

|
Some text that should be checked next year.{{Update after|{{#expr:{{CURRENTYEAR}}}}}}

|
{{Tlx|Update after|''year''|''month''|''day''|''category''}} also adds the article to the specified category (which should be specified without square brackets and without the "Category:" prefix).

An optional reason may be used as a comment to future editors.

<code>Some text that should be checked.{{Tlx|Update after|reason{{=}}check for population growth}}</code>
|
Some text that should be checked.{{Update after|reason=check for population growth}}
|-
| Dated statement may be included in the template using the {{para|text}} param.

== Effects ==

When the template is activated in an article, the phrase "needs update" appears in the text of the article at the indicated spot. The page will also appear in [[:Category:Wikipedia articles in need of updating]] or one of its dated subcategories, when the date is specified, and also any category specified in the 4th parameter.

See [[:Category:Wikipedia articles in need of updating]] for a list of pages currently needing updates, and [[Wikipedia:As of]] for a list of 'As of' pages.

== Related templates ==
* {{Tlg|Update inline}} or {{Tlg|Update inline span}} can be used if the text is already outdated, instead of adding this template with a date in the past.
* {{Tlg|Update}} can be used to mark an entire article or section needing to be updated. Like {{Tl|Update after}}, this template adds the article to [[:Category:Wikipedia articles in need of updating]].
* {{Tlg|Update|inaccurate{{=}}yes}} is used to mark an article which may now have inaccuracies (not just missing information) due to being outdated. This template adds the article to [[:Category:Articles with obsolete information]].
* {{Tlg|As of}} is used to mark potentially dated statements, and will add an article to the appropriate [[WP:HIDDENCAT|hidden]] sub-category of [[:Category:Articles containing potentially dated statements]].
* {{Tls|Show by}}/{{Tlg|Show by date}} Shows one of 2 strings depending upon date
* {{Tlg|Age switch}} can be used to build date-related templates.
