{{tlb|Start and end dates}} returns 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 [[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.

== 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 [[microformat]]-emitting templates—if in doubt, see the parent template's documentation
* more than one date in any parent template

== Usage ==
{{tlx|Start and end dates|{{var|YYYY}}|{{var|MM}}|{{var|DD}}|{{var|YYYY}}|{{var|MM}}|{{var|DD}}}}

== Examples ==
* Standard: {{tlx|Start and end dates|1939|9|1|1945|9|2|_show_result=yes}}
* Day first: {{tlx|Start and end dates|1939|9|1|1945|9|2|df{{=}}yes|_show_result=yes}}
* Same year: {{tlx|Start and end dates|1939|9|1|1939|10|2|_show_result=yes}}
* Same month and year: {{tlx|Start and end dates|1939|9|1|1939|9|2|_show_result=yes}}
* Present range: {{tlx|Start and end dates|1939|9|1|present|_show_result=yes}}

== TemplateData ==
