DATEVALUE will convert a string to a conventional date. You could do a
find and replace operation on your query marks, but that would then
obscure the uncertainty, which you may wish to highlight.
So, you might come up with a big formula to do it all for you, like
this:
=DATEDIF(DATEVALUE(IF(RIGHT(A1,1)="?",1,RIGHT(A1,2)) & "/" &
IF(MID(A1,6,1)="?","January",MID(A1,6,2)) & "/" &
IF(LEFT(A1,1)="?",1950,LEFT(A1,4))),TODAY(),"y")

I assume Robert is using Excel, since most of his recent questions have
been about Excel.

You are correct, I am using Excel. It took me all of 30 seconds to fall
in love with DATEDIF. I wish I had known about this earlier. Thank you!
A query for you please. Suppose E1 is text, and contains 1922-10-10 as a
person's birthdate. The death date is also text. Is there an easy way to
convert that to a "real" date? LOL, I spent NINE hours trying to get
Datedif to work, only to discover the numbers were not even date format!
I do see a problem with the dates which explains why the original person
made it text. The original person used the question mark symbol to
denote unknown. 1905-??-17 for example, means the month is unknown.
Am I going to need to do something about the question marks one at a
time?
Thank you.
Robert
