end_date=* was designed to indicate when a feature went out of service, or was demolished. See start_date=* for details of formatting of dates.
Please see Comparison of life cycle concepts for better alternatives.
Except for special cases use of this unapproved tag breaks backward compatibility - as a result map features (such roads) which are no longer existent may be displayed as existing or confuse routers. In particular it should not be used for roads or other important features as most rendering and routing engines will ignore it and provide wrong information.
This tag is slightly hard to use, because if a building is gone you should just delete it. It's also not always obvious what end_date refers to, I recommend adding a note and making it clear how you are using this tag. In 2014 there were 12 000 usages of this tag in the DB, e.g. try to understand what version 2 ofactually means.
