This module is rated as ready for general use. It has reached a mature state, is considered relatively stable and bug-free, and may be used wherever appropriate. It can be mentioned on help pages and other Wikipedia resources as an option for new users. To minimise server load and avoid disruptive output, improvements should be developed through sandbox testing rather than repeated trial-and-error editing.

This Lua module is used on approximately 47,000 pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own module sandbox. Consider discussing changes on the talk page before implementing them.

This module is intended for processing of date strings. It is used by Module:WikidataIB

option. See c:Template:Other date

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 era is present, it overrides these two parameters.

The internationalization of the date formats can be found at Module:I18n/complex date

Module:Complex_date relies on the following modules:

• 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)

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.

Unless otherwise noted, the authoritative version of each module can be found on Commons.
