Template:Start date and number of years

Syntax

To display the Start date only

{{Start date and number of years|year of birth|month of birth|day of birth|additional parameters}}

Do not use with non-Gregorian dates because the resulting hCard hidden date will be false.

To display a Start date with calculated number of years

{{Start date and number of years|YearOfStart|Month|Day|additional parameters}}

This form is only intended for living persons. For dead persons, use {{birth date}}. In the rare case that a living person's birth date is given in a non-Gregorian calendar this template should not be used. The parameter names 'year', 'month', and 'day' can be used instead of the first, second, and third parameters for 'Birth date and age' only. These parameter names are not available for the 'Birth date' template. However, as per WP:DOB, a full birth date for a living person should only be displayed when it can be cited as being widely published, or published with the clear approval of the person involved. Otherwise, use {{birth year and age}} instead.

{{Bda}} is a redirect to {{Birth date and age}}

{{Bda|year of birth|month of birth|day of birth|additional parameters}}

Examples

{{Start date and number of years|1993|2|4|df=yes}} returns (1993-02-04) 4 Template:MONTHNAME 1993

{{Start date and number of years|1993|2|4|mf=yes}} returns (1993-02-04) Template:MONTHNAME 4, 1993

{{Start date and number of years|1993|2|4}} returns (1993-02-04) Template:MONTHNAME 4, 1993

{{Start date and number of years|1993|2|24|df=yes}} returns (1993-02-24) 24 Template:MONTHNAME 1993

{{Start date and number of years|1993|2|24|mf=yes}} returns (1993-02-24) Template:MONTHNAME 24, 1993

{{Start date and number of years|1993|2|24}} returns (1993-02-24) Template:MONTHNAME 24, 1993

"month first" (mf) and "day first" (df) options

The df (day first) and mf (month first) parameters indicate the intended date format to display. The appropriate parameter should be set to "y" or "yes" e.g. df=yes or mf=y.

The default output of this template is to display the month before the day. This default may not be appropriate for articles about people from parts of the world where the day precedes the month in a date. In such articles the parameter, "df", should be set to display the day before the month.

The parameter "mf", while not actually used by the template, will indicate that month first format is intended. Using these parameters can assist bots or other automated processing to detect which date format is intended; leaving the format as default may lead an editor or bot to change the format to an unintended value.

Do not specify both "df" and "mf" parameters in the same use of the template, as these formats are mutually exclusive.

Examples

{{Start date and number of years|1993|2|24|df=yes}} displays " (1993-02-24) 24 Template:MONTHNAME 1993".

{{Start date and number of years|1993|2|24|mf=yes}} displays " (1993-02-24) Template:MONTHNAME 24, 1993".
