| | This template will return a living person's date of birth and age. Using this template rather than simply inserting the date into articles allows for the inclusion of hidden metadata about the date. This metadata can be used by web browsers and other software tools to extract the details, and display them using some other website or mapping tool, index, or search them. |

| |
| ==Usage==
| |
| These templates ('''{{tl|Birth date}}''' and '''{{tl|Birth date and age}}''') return a person’s date of birth and optionally his/her age. The latter also has the shortcut: '''{{tl|Bda}}'''.
| |
|
| |
|
| <big style="color:#CC0000;">Do NOT use this template when the person's exact date of birth is disputed or unknown.</big>
| | This template is intended for use in an article about a living person. For an article about a dead person, use {{tl|Birth date}} with {{tl|Death date and age}}. |

| | {{notice|text='''Is the displayed age incorrect?'''<br>The age displayed was calculated when the page was last purged. If a particular article is showing the wrong age, edit the whole page and publish the edit without making any change and with no edit summary. That will update the age. The page can also be purged by appending <code>&action=purge</code> to the URL.}} |

| ===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 '''df''' (day first) and '''mf''' (month first) parameters indicate the intended date format to display.

|
| The default output of this template is to display the month before the day.

| | | Some kinds of invalid input are tracked in [[:Category:Pages using age template with invalid date]]. |
| :<nowiki>{{Birth date | 1993 | 2 | 24 | df=yes }}</nowiki> displays "24 February 1993".
| |
| | |
| :<nowiki>{{Birth date and age | 1993 | 2 | 24 | df=yes }}</nowiki> displays "24 February 1993 (age {{Age|1993|2|24}})".

| | |
| ===hCard microformat===
| |
| | |
| The templates also return the date, hidden by CSS, in the [[ISO 8601]] format needed by [[HCard|hCard microformat]]s. for example:
| |
| | |
| :<nowiki>(<span class="bday">1993-02-24</span>)</nowiki>
| |
| | |
| Note: for the "foundation", "built" and similar set-up dates of companies, buildings, etc, use {{tl|Start date}} (this will work for year-only or month-year dates).
| |
| | |
| See [[WP:UF|the microformats project]] for details.
| |
| | |
| ===Notes===
| |
| | |
| When only the year of a person's birth and/or death are known, or if it is desired not to state a person's full dates of birth and death for privacy reasons, use the templates {{tl|Birth year and age}} and {{tl|Death year and age}} instead.
| |
| | |
| '''Note:''' The template will appear broken when the parameters are left blank (as seen above).
| |
| | |
| '''Note:''' Do not use this template inside of the [[WP:PERSONDATA|Persondata]] template as it can interfere with data extraction.
