An approximated date in the future when a construction will be finished, used for example on landuse=construction and highway=construction. It is recommended to additionally add check_date=*, which describes the date in the past, when the value of opening_date=* was actually checked.

Format: YYYY-MM-DD (ISO 8601 format)

Avoid combinations such as building=yes + opening_date=future as this would break lots of existing software (see trolltags). This can be avoided by using a lifecycle prefix like construction:building=yes or the specific methods established for roads and railways.

Example: opening_date=2018-11-10 - 10 November 2018

Practical use

http://overpass-turbo.eu/s/Hvm may be used to detect opening_date=* with date in past - so object that probably should be resurveyed as either construction completed or opening date changed.
