So, what does the 'Certain' birth date mean? I've always assumed it was meant to be an exact date ... day/month/year ...
I've had a couple of profiles that were modified recently and the birth/death date changed from a year I marked as approximate to a year that was marked as 'Certain' ... and, of course, without a source ... grrrrr!
So, is 'certain' applicable to day, date, and year?
