* {{Mlx|{{BASEPAGENAME}}|dates}} - formats the date range.
* {{Mlx|{{BASEPAGENAME}}|start_end_date_template_validation}} - checks if the values of {{para|first_aired}} or, {{para|released}}, {{para|aired}}, {{para|released_date}} are not passed via {{tlx|Start date}} and if the value of {{para|last_aired}} is not passed via {{tlx|End date}} (or is not {{para|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 {{para|error_category}} if used.
