Template:Start and end dates/doc

This purpose of the 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 microformats. 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", 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

Syntax

 * Examples
 * Standard:  →
 * Day first:  →
 * Same year:  →
 * Same month and year:  →
 * Present range:  →
