Module:Date table sorting/sandbox

This is the module sandbox page for Module:Date table sorting (diff).

Module documentation

Usage

Generates a <time data-sort-value=[standardized-date] datetime=[standardized-date]>[formatted date]</time> tag, where [standardized-date] is in ISO 8601 format (e.g. 2020-07-25), and [formatted date] is in a customizable format.

From a content page, you should use {{Date table sorting}}.
From a template, you should invoke main function {{#invoke|main}}
From a module, you should call _main function require('Module:Date table sorting')._main

Arguments can be passed through either template call or Module invokation.

Arguments

lang: Code of the language in which you want to display the date. In most cases, it should be {{PAGELANGUAGE}} (from a Lua module, you can get it with frame:preprocess( '{{PAGELANGUAGE}}' )).
format: Deprecated (kept for backware compatibility). Use phpformat instead.
phpformat: Date display format: any string supported by {{#time}} (you can read its documentation page). Defaults to "j xg Y" (e.g. “6 January 2020”).
precision: Instead of setting a phpformat, the module can guess it from date precision integer: 9 will display only year, 10 will display month and year, and 11 will display day, month and year. These values come from Wikidata date data model.
date: full date (takes precedence over other date arguments)
year: year (takes precedence over numbered date arguments)
month: month (works only if year is set)
day: day (works only if both year and month are set)
1: full date or year
2: month (works only if 1 is set)
3: day (works only if both 1 and 2 are set)
