assuming your dates are in the format YYYY-MM-DD, you can use
=DATE(LEFT(A1,4),MID(A1,6,2),RIGHT(A1,2))
(assuming the date is in cell A1) to return the number used by Excel as
the
corresponding date.
To get around the question marks, you might complete the formula as
such:
=IF(AND(ISNUMBER(VALUE(LEFT(A1,4))),ISNUMBER(VALUE(MID(A1,6,2)));ISNUMBE
R(VALUE(RIGHT(A1,2)))),DATE(LEFT(A1,4),MID(A1,6,2),RIGHT(A1,2)),0)
which will return the date if Year, Month and Day are numeric and return
zero if any of them are not.

Whups, problem, at least on my end.
Suppose:
Birthdate in A1 is "????-??-??"
Death date in B1 is "1987-03-20"
The formula returns 1900-Jan-00 for the Birthdate in A1.
The formula returns 1987-Mar-20 for the deathdate in B1
Then, my age formula computes 87 years, 2 months, 0 days. Hmm, any
suggestions? Would it work if I "trap" the 1900-Jan-00 dates and just
have it enter "Nondeterministic" for the age?
Thank you.
Robert
