This purpose of the '''{{tl|start and end dates}}''' template is to return the date range during which an event transpired or an entity existed. It also includes duplicate, machine-readable date (or date-time) in the ISO date format (which is hidden by CSS), for use inside other templates (or table rows) which emit [[Wikipedia:microformat|microformat]]s. '''It should be used only once in each such template''' and '''never used outside such templates'''. The hidden date degrades gracefully when CSS is not available.

== Usage ==

===When not to use this template===
Do not use this template for:
* dates that are uncertain e.g., "before 4 April 1933"; "around 18 November 1939".
* dates outside the range given under "[[#Limitation|Limitation]]", below.
* other, secondary dates
* outside [[Wikipedia:microformat|microformat]]-emitting templates - if in doubt, see the parent template's documentation
* more than one date in any parent template

===Syntax===
* {{tlx|start and end dates|year|month|day|year|month|day}}

Example: <code><nowiki>{{start and end dates|1939|9|1|1945|9|2}}</nowiki></code> → {{start and end dates|1939|9|1|1945|9|2}}

Example (day first): <code><nowiki>{{start and end dates|1939|9|1|1945|9|2|df=yes}}</nowiki></code> → {{start and end dates|1939|9|1|1945|9|2|df=yes}}
