The{{Start date and age}} template displays the date that an event or entity started or was created. It also includes a duplicate, machine-readable date in theISO 8601 format (which is hidden byCSS), for use inside other templates which emitmicroformats. The hidden date degrades gracefully when CSS is not available.
A number between 1 and 12 indicating the month (leading zeros in the number are ignored). The month may also be specified as a name or abbreviation (e.g. "August" or "Aug").
3
optional
A number between 1 and 31 indicating the day of the month (leading zeros in the number are ignored).
df=
optional
If the parameterdf equalsyes,y, or1, the date will be displayed in DMY format:4 March 2010. When this parameter is not included or set to some other value, the date will be displayed in MDY format:March 4, 2010.
p= paren=
optional
If the parameterp orparen equalsyes,y, or1, the age will be displayed within parentheses. When this parameter is not included or set to some other value, the date and age are separated by a semicolon and a breaking space.
br=
optional
If the parameterbr equalsyes,y, or1, a line break will be inserted between the date and the age. When this parameter is not included or set to some other value, 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 (ifp=yes).
The default output of this template is to display the month before the day (MDY). This default may not be appropriate for articles about events or entities in parts of the world where dates are commonly given with the day preceding the month (DMY). To display the day first, assign thedf parameter a value ofyes,y, or1 (e.g.df=yes).
If the default format is preferred, the parameterdf may be used with value ofno,n, or0 (e.g.df=no). These values can assistbots or other automated processing to detect the intended date format; omitting thedf parameter may lead an editor or bot to change the format to an unintended value.
The preference to display the month first may also be indicated via the parametermf (e.g.mf=yes). While not actually used by the template, this is another method of indicating that the default format is intended. Do not specify both "df" and "mf" parameters in the same use of the template.
This template has no provision to deal with a date in a non-Gregorian calendar. Also,ISO 8601 requires mutual agreement among those exchanging information before using years outside the range 1583-9999 CE. Therefore, use of this template for non-Gregorian dates or dates outside that range constitutes afalse claim of conformance to the ISO 8601 standard.
Any editor encountering such usage should change the date to plain text with no template; or if not confident in doing so, raise the matter on this template's talk page.
This template is most often used in infoboxes in articles about buildings or organizations, identifying when they were started/founded/opened or dissolved/ended/closed.
It has also been used for naval ships to indicate their commissioned age, however several Wikipedia editors have reverted such edits. Use of this template in ship articles is therefore not recommended.
Combines functions of {{Birth date}}, {{birth-date}}, {{birth date and age}}, {{birth year and age}}, {{death date}}, {{death-date}}, {{death date and age}}, and {{death year and age}}.
To display approximate birth year and current age given a particular date (e.g. when a dated reference mentions the age of a person), only works for living people.

Use microformat for end date

This template includes hidden microformat <span>, similar to Template:Start date. If the parameter end equals yes, y, or 1, the template will instead use <span>, similar to Template:End date. This parameter is used by Template:End date and age. For more details, see Wikipedia:WikiProject Microformats.
