 == Usage ==
 
 This module is intended for processing of date strings. It is used by [[Module:WikidataIB]]
 
 ==Complex date==
 This function is the engine behind [[c:template:Complex date]]. Please see that template for full documentation
 
 ====Usage:====
 :should not be used directly but only through [[c:Template:Other date]] and other templates
 :&lt;code&gt;&lt;nowiki&gt;{{#invoke:Complex_date|complex_date|adj1=|date1=|era1=|precision1=|conj=-|adj2=|date2=|era2=|precision2=|lang=}}&lt;/nowiki&gt;&lt;/code&gt;
 or
 :&lt;code&gt;&lt;nowiki&gt;{{#invoke:Complex_date|complex_date|1=|2=|3=|era=|lang=}}&lt;/nowiki&gt;&lt;/code&gt;
 
 ====Parameters (simple syntax):====
 ;1
 :option. See [[c:Template:Other date]]
 ;2
 :date #1
 ;3
 :date #2
 
 ====Parameters (advanced syntax):====
 ;conj
 : in case the link between the two dates: &quot;-&quot; (from-until), between, or, and  (see [[c:template:Complex date]])
 ;adj1, adj2
 : adjectives and prepositions used to describe single date. Possible values: ''early'', ''mid'', ''late'', ''spring, summer, fall, winter, 1st half, 2nd half, 1st quarter, 2nd quarter, 3rd quarter, 4th quarter'', etc. used for describing which part of date1 and date2 are involved (see [[c:template:Complex date]])
 ;date1, date2
 : the dates involved. Format: Number or whatever {{tl|ISOdate}} takes.
 ;precision1, precision1
 : usually ''year'' or more precise (default), but can also be ''decade'', ''century'' or ''millennium'',  then the dates involved are centuries or millennia rather than specific dates
 ;era1, era2
 : the eras that those dates are from (see [[c:template:Complex date]])  If parameter &lt;code&gt;era&lt;/code&gt; is present, it overrides these two parameters.
 
 The internationalization of the date formats can be found at [[Module:I18n/complex date]]
 
 ==Dependencies==
 [[Module:Complex_date]] relies on the following modules:
 * [[Module:Calendar]] (lazy loading with no dependencies)
 * [[Module:ISOdate]]
 ** [[Module:DateI18n]] (no dependencies)
 * [[Module:i18n/complex date]]
 ** [[Module:Ordinal-cd]] (lazy loading)
 *** [[Module:I18n/ordinal]] (no dependencies)
 *** [[Module:Yesno]] (from en.wikipedia) (no dependencies)
 *** [[Module:Formatnum]] (no dependencies)
 ** [[Module:Roman-cd]] (lazy loading with no dependencies)
 ** [[Module:Linguistic]] (lazy loading with no dependencies)
 Several of the lazy-loaded dependencies do not exist locally since none of the code that calls them ever ends up used on the English Wikipedia.
