Modul:Infobox/dates/doc

Usage

• {{#invoke:infobox/dates|dates}} - formats the date range.
• {{#invoke:infobox/dates|start_end_date_template_validation}} - checks if the values of |first_aired=, |released=, |aired=, |released_date= are not passed via {{Start date}} and if the value of |last_aired= is not passed via {{End date}} (or is not |last_aired=present, where relevant). If they aren't, the function returns the default error category, Category:Pages using infobox television with nonstandard dates or the error category from |error_category= if used.
