Usage
Use {{TBD}} as a placeholder for forthcoming information, such as the date of an upcoming event, title of a to-be-released film or album, or other missing data. This template should only be used when the upcoming "whatever" has been sourced except for this particular as-yet-undetermined detail. It must not be used for supposition or prediction, and not for missing but findable information. Ideally, the very fact that the information is presently undetermined should itself be reliably sourced.
As with other inline templates of this sort, it should not be substituted with "subst:".
Articles tagged with {{TBD}} will be added to Category:Wikipedia articles containing placeholders, which can be used to find articles that are likely in need of updating after a significant amount of time has passed since the dates that this template was added to them.
Optional parameters
Optionally, {{TBD}} can be supplied with a date by which the information that is missing is expected to become available:
{{TBD|year|month|date}}
After the specified date, the placeholder will be displayed as
For more details, see {{update after}}.
