Assuming the first 6 lines below
are within A2:B7, viz:

12/16/2007 = 1A
12/17/2007 = 2A
12/18/2007 = 3A
12/19/2007 = 1B
12/20/2007 = 2B
12/21/2007 = 3B

Select A2:B7, fill down to propagate the series for future dates as far as
required. Then just use a simple vlookup on the input date,
eg with input date in D2 down: 12/21/2007
Put in E2: =IF(D2="","",VLOOKUP(D2,A:B,2,0))
Copy down

Using the following pattern:

DATE = ANSWER
---------- ------
12/16/2007 = 1A
12/17/2007 = 2A
12/18/2007 = 3A
12/19/2007 = 1B
12/20/2007 = 2B
12/21/2007 = 3B
12/22/2007 = 1A
12/23/2007 = 2A
12/24/2007 = 3A
12/25/2007 = 1B
12/26/2007 = 2B
12/27/2007 = 3B
12/28/2007 = 1A
12/29/2007 = 2A
12/30/2007 = 3A

how can I calculate the "ANSWER" when "DATE" = January 27, 2008?

DATE = ANSWER
---------- ------
1/27/2008 = ?


or any other date for that matter?


Thank you.
