Template:As of/doc

Usage
The template as of is used to mark potentially dated statements, and will add an article to the appropriate sub-category of Category:Articles containing potentially dated statements. This allows editors to catalogue statements that may become dated over time. The date used for a given statement should be the current date (for currently valid statements) or the date on which the cited reference was produced (for example, when using census data). Unlike the update after template, as of does not require the editor to give a full date. This template should not be subst'd.

Syntax
The template can be used in the following forms:


 * {&#123;As of|year|month|day&#125;}
 * {&#123;As of|year|month&#125;}
 * {&#123;As of|year&#125;}

Several additional named parameters can also be used (see below).

Parameters
Required
 * year (first parameter) – must be in full numerical format (yyyy)

Optional
 * month (second parameter) – full, abbreviated or numerical formats supported (mm recommended)
 * day (third parameter) – numerical format only, not included in link (dd)

Named
 * alt – optional; allows substitution of different wording and case for the visible text output; if present but no value defined, this parameter is ignored; if a value is defined, values for df and lc parameters are ignored
 * df – optional; allows use of American date format with df=US
 * lc – optional; gives lower case "as of date" when defined; recommended syntax is lc=y
 * url – optional; adds an inline external link (hidden by default) suggesting a webpage for future editors to check for updates to the statement; use the full URL with no spaces. See Wikipedia:As of for displaying links.
