Wikidata

An approximated date in the future when a construction will be finished, used for example on landuse=construction, highway=construction or building=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

Date format compatible with ISO 8601: YYYY-MM-DD (year-month-day).

For example: opening_date=2024-08-09 – 9 August 2024

Remember that this date should be a future date.

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.

Practical use

Opening dates in the past should be resurveyed as either construction completed or opening date changed:
