{{tlb|Start and end dates and age}} returns the date range during which an event transpired or an entity existed as well as the timespan, or age, of the event, with the time units and formatting between the dates and age being able to be specified. 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 and age|{{var|YYYY}}|{{var|MM}}|{{var|DD}}|{{var|YYYY}}|{{var|MM}}|{{var|DD}}|{{var|agein}}|{{var|formatting}}}

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

== TemplateData ==
