Template:Start date and age/doc

This purpose of the start date template is to return the date (or date-time) that an event or entity started or was created. 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

 * (MM and SS are optional; TimeZone may be a numerical value, or "Z" for UTC; see examples)

 * → "08:30, February 24, 1993"
 * → "February 24, 1993 (+01:00)"
 * → "February 24, 1993 (-07:00)"
 * → "08:30:23, February 24, 1993"

 * → "08:30:23, February 24, 1993 (+01:00)"
 * → "08:30:23, February 24, 1993 (-07:00)"

An optional parameter,, can be set to "y" or "yes" (or indeed any value) to display the day before the month. This is primarily used in articles using DMY format for dates.


 * Examples
 * → "February 24, 1993"
