 | Do not use this template when the person’s exact date of birth is disputed or unknown. |
The {{Birth date}} and {{Birth date and age}} templates will return a person’s date of birth and optionally his/her age. They have the shortcuts {{dob}} and {{bda}}, respectively.
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.
