|This key is not proposed to use in main OpenStreetMap! Instead, its usage is supported in the OpenHistoricalMap, where you can map features that are gone with their lifecycles.|
end_date=* was designed to indicate when a feature is planned to go out of use, or when it went out of service, or when it was demolished. It is used in separate historic mapping projects but should not be used for this purpose in the main OSM database.
Please see Comparison of life cycle concepts for alternatives.
If not used carefully this tag can break things, for example map features (such as roads) which are no longer existent will 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. Developers have repeatedly expressed their unwillingness to support end_date - see also troll tag.
This tag could be used with an additional lifecycle prefix in combinations like removed:building=... + end_date=....
It's also not always obvious what end_date=* refers to if applied to an object with multiple tags.
E.g. try to understand what version 2 ofactually means.
Sometimes it is erroneously used to note planned completion date of construction - for example of highway=construction, though this use should use opening_date=*, even if that date is yet in the future.
See start_date=* for details of formatting of dates.
