How to valid the date with given condition?
 

Does anyone have any suggestions on how to valid the date with given condition?
For example, there is a list of date under column A,
01-May-06
06-May-06
11-May-06
13-May-06
25-May-06
....
There is a given date in cell B1 [20-May-07] and a given number 6 in cell B2.

I would like to determine any date under column A within the range based on
the given date [20-May-07] + / - the given number 6 days, which is between
[14-May-06] and [26-May-06]. If none exists within this range, then return
FALSE in cell C1, else if any date or more exist within this range, then
return TRUE in cell C1.
Does anyone have any suggestions on how to do it?
Thanks in advance for any suggestions

Try this:

the given date [20-May-07] + / - the given number 6 days, which is between
[14-May-06] and [26-May-06].

I think your years are messed up!

=COUNTIF(A1:A5,"="&B1-B2)-COUNTIF(A1:A5,""&B1+B2)0
