Date when feature happened historic=* (Status: de facto) / Does a clock amenity=clock also show the current date? (Status: "approved" ).

This tag was also heavily used for other, unknown reasons (for example date=2014 added to most minor roads in one rectangle in Mexico)

Some uses by mappers included specifying date when feature was mapped.

Formatting

historic=*

Dates use the ISO 8601 system, which is based on the Gregorian calendar.

Examples:

  • 2010 ; where the year is known, but no more
  • 0897 (for 897 AD)
  • 1848-07 ; where the year and month are known
  • 2010-03-31 ; for where the full date is known, using the format yyyy-mm-dd

Caution: ISO8601 uses the format yyyy-mm-dd, not the common North American model of mm-dd-yyyy

amenity=clock

  • date=yes - The clock also shows the current date. Default value: no.
  • date=no - The clock does not show the current date

  • start_date=* - Date when feature opened or the construction of the feature finished
