Template:Update after
 | This template is used on approximately 5,200 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
This template is used to flag statements that are likely to become outdated by a specific future date.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 Manual of Style on chronological items, the editing guidelines on precise language and updating information, and Wikipedia:As of.
Usage
{{Update after|year|month|day|category|reason=...|text=...}} (all parameters are optional)
- For inline usage, similar to {{Citation needed}}.
- If piece of text is already outdated, use {{Update inline}} or {{Update inline span}} instead.
- {{Update}} can be used to mark an entire article or section needing to be updated. {{Outdated as of}} could be used to automatically trigger it for articles that will need to be improved due to an already determined future development.
- {{Update|inaccurate=yes}} is used to mark an article which may now have inaccuracies (not just missing information) due to being outdated.
Parameters
- Parameters
|1=,|2=, and|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 bot will add the date the template was added to the article later. - Parameter 4 is a custom 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
|4=.- Examples: Specifying
|4=United States articles in need of updatingplaces the article in Category:United States articles in need of updating as well as Category:Wikipedia articles in need of updating.
- Examples: Specifying
- Parameter
|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
|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
|delay=specifies an additional number of days to delay activation of the template after the specified date.
Do not. . .
Please read Wikipedia:Avoid statements that will date quickly, Manual of Style on chronological items, the editing guidelines on precise language and updating information, and Wikipedia:As of; use {{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 talk pages; it is intended for inline usage, like {{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.
