Template:End date and age/doc

The {{End date and age}} template displays the date that an event or entity ended. 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.

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). 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 parameter df equals yes, y, or 1, 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 parameter p or paren equals yes, y, or 1, 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 parameter br equals yes, y, or 1, 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 (if p=yes).

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

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 the df parameter a value of yes, y, or 1 (e.g. df=yes).

If the default format is preferred, the parameter df may be used with value of no, n, or 0 (e.g. df=no). These values can assist bots or other automated processing to detect the intended date format; omitting the df 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 parameter mf (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.

Use in microformats

The template returns the date as hCalendar's (class="dtend"). For example:

(<span class="dtend">1993-02-24T08:30</span>)

(disable CSS or view source to see the hidden ISO-formatted output).

See the microformats project for further details.

Supporting templates

This template is a wrapper for Template:Start date and age which uses the following templates:

• Template:MONTHNAME – display name of month for a given number 1 (January) through 12 (December).
• Template:Time ago – display number of days, months, or years ago (for dates given as |yyyy|mm|dd).
• Template:Years or months ago – display number of months or years ago (for dates given as |yyyy|mm or |yyyy).
• Template:Yesno – allows optional formatting parameters to accept values other than "yes" (such as "y" or "1").

• {{End date}}
• {{Time ago}} and {{Years or months ago}}
• {{Age}}

There are a number of templates that you can use to set out a person's birth date or birth year, current age, death date or death year, and age at death. This is especially useful in infoboxes. Using these templates rather than simply inserting dates into articles allow hidden metadata about dates to be put into articles. Web browsers and other types of software can look up the metadata and use them for certain types of displays or searches.

The year, month and day of birth and death dates must be typed in numbers. If a number is smaller than ten, you do not have to type a zero before it (for example, you can type "7" instead of "07").

Notes

{{Birth date and age}} and {{Birth year and age}}

In {{Birth date and age}} and {{Birth year and age}}, the person's age is calculated based on the current date.

{{Birth year and age}} and {{Death year and age}}

The templates {{Birth year and age}} and {{Death year and age}} show a person's year of birth or death and his or her approximate (rough) age. The templates are useful when only the year of a person's birth and/or death are known, or if you do not want to state a person's full dates of birth and death for privacy reasons.

The person's age is estimated in the following way:

• {{Birth year and age}} – let us assume:

1. that the person in question was born some time in 1969; and
2. that the present date is 22 December 2024.

If the person was born before 22 December 1969 then he will be 54 years old on 22 December 2024 as he has not had his 55th birthday yet. On the other hand, if he was born exactly on or before 22 December 1969, then he will be 55 years old.

Therefore, the template {{Birth year and age|1969}}

displays his birth year and age as: 1969 (age 54–55)

• {{Death year and age}} – let us assume:

1. that the person in question was born some time in 1973; and
2. that she died some time in 2023.

We can think of two extremes: (1) that the person was born on 31 December 1973 and died on 1 January 2023, in which case she would have been 49 years old at the time of her death as she did not achieve her 50th birthday on 31 December 2023; and (2) that she was born on 1 January 1973 and died on 31 December 2023, in which case she would have been 50 years old at the time of her death as she had her 50th birthday on 1 January 2023.

Therefore, the template {{Death year and age|2023|1973}}

shows her death year and age as: 2023 (aged 49–50)

Templates allowing day to be shown before month

The templates in the table below take an optional parameter "df" (which stands for "date first") – you can choose whether to use it or not. If "df=yes", then the day of the date is shown before the month. This is for articles about people from parts of the world where the day usually comes before the month in a date.

What you should type	Example	What you will see
{{Birth date|[year of birth]|[month of birth]|[day of birth]|df=yes}}	{{Birth date|1965|8|9|df=yes}}	(1965-08-09)9 August 1965
{{Birth date and age|[year of birth]|[month of birth]|[day of birth]|df=yes}}	{{Birth date and age|1965|8|9|df=yes}}	(1965-08-09) 9 August 1965
{{Death date|[year of death]|[month of death]|[day of death]|df=yes}}	{{Death date|2005|12|25|df=yes}}	25 December 2005
{{Death date and age|[year of death]|[month of death]|[day of death]|[year of birth]|[month of birth]|[day of birth]|df=yes}}	{{Death date and age|2005|12|25|1965|8|9|df=yes}}	25 December 2005(2005-12-25) (aged 40)
