Terms For Unknown Dates

In a database of artworks when the date that the artwork was made it not exactly known the term circa (ca.), active, late, or early are placed in front of a date. Would you call these terms 'date qualifiers'?


Solution 1:

Possibly date qualifiers is an appropriate name, though it seems a bit "off" in that the term does not immediately bring to mind what it is.

Some alternatives might be:

  • date specificity
  • date modifier
  • date adverb
  • date uncertainty
  • uncertain date phrase
