Template:Start date and age

Template documentation[view] [edit] [history] [purge]

{{Start date and age}} displays the date that an event or entity started or was created. It also includes a duplicate, machine-readable date in the ISO 8601 format (which is hidden by CSS), for use inside other templates which emit microformats. The hidden date degrades gracefully when CSS is not available.

Usage

• {{Start date and age|YYYY|MM|DD}} (year, month, and day)
• {{Start date and age|YYYY|MM|DD|df=yes}}
• {{Start date and age|YYYY|MM|DD|df=yes|p=yes|br=yes}}

Parameters

Parameter	Status	Description
1=	required	A four-digit number indicating the year.
2=	optional	A number between 1 and 12 indicating the month (leading zeros in the number are ignored).
3=	optional	A number between 1 and 31 indicating the day of the month (leading zeros in the number are ignored).
df=	optional	df=yes or |df=y displays the day before the month (e.g. "7 November 2004" instead of the default "November 7, 2004").
p= |paren=	optional	p=yes or |p=y the age will be displayed within parentheses. When this parameter is not included, the date and age are separated by a semicolon and a breaking space.
br=	optional	br=yes or |br=y a line break will be inserted between the date and the age. When this parameter is not included, a breaking space will be inserted between the date and the age. This does not change the separating characters between the date and age which are either a semicolon (default setting) or parentheses (if |p=yes).
