I have read so many posts but i am not grasping the use of dates.
My problem seems simple, in my mind, but it is not in excel.
I have a worksheet that will have dates in a range and each date needs to be
checked for expiration, is it 10 months and or 1 year old from current date
(current date is every/any day I use the workbook).

Any help is appreciated!

Start by visiting Chip Pearson's coverage of Excel's unexplainably
undocumented DATEDIF function:
http://www.cpearson.com/excel/datedif.htm

Then...for a date in A1...perhaps a formula like this:
=CHOOSE(SUM((DATEDIF(TODAY(),A1,"M")={10,12})*{1,2 })+1,"na","10 mths","1
year")

Is that something you can work with?

I think the OP is wanting to know if A1 is 10 or 12 months prior to today's
date. If so, he'll need a small change to:

=DATEDIF(A1, TODAY(),"M")

Although he should pick up on that if he follows up on your suggestion to
read the link you provided.

The things most of you on this BB can do amaze me, on that note, I am flat
out failing to understand the use of the function provided on Chips website.

Function Age(Date1 As Date, Date2 As Date) As String
Dim Y As Integer
Dim M As Integer
Dim D As Integer
Dim Temp1 As Date
Temp1 = DateSerial(Year(Date2), Month(Date1), Day(Date1))
Y = Year(Date2) - Year(Date1) + (Temp1 Date2)
M = Month(Date2) - Month(Date1) - (12 * (Temp1 Date2))
D = Day(Date2) - Day(Date1)
If D < 0 Then
M = M - 1
D = Day(DateSerial(Year(date2), Month(date2), 0)) + D
End If
Age = Y & " years " & M & " months " & D & " days"
End Function

I have worked out a scenrio via DateDif (worksheet) but there are to many
dates to check in this manner. Any help on the use of the above function
will be appreciated.

This might be easier to work with:

Public Function CurrentAge(dBirthdate As Date) As Integer
CurrentAge = DateDiff("yyyy", dBirthdate, Date)
End Function

See the DATEDIFF function in VBA help (note the 2 F's)

Does that help?

I have much to learn about the use of Functions. The info you supplied along
with reading about Datediff (2 f's) did help me understand the format for
Datediff itself.

Thank you for your time and help!!!
