vlookup with time range

[pencil_pusher]

I want to know if the time in sheet1 A2 matches any time (plus or minus 12 hours) in sheet2 A2:B546, if so, then return the value for sheet2 A2. I'm getting hung up on the "plus or minus 12 hours". Can I use vlookup for this or will it not work because the range does not consist of single values?

Do the times run from zero upwards (eg race times) or are they times of the day, in which case how do you know if 6pm is from the previous day or the current day for comparison? Also how are the times formatted?

They are times of day including the date. They are formatted as dates mm/dd/yyyy hh:mm.

Okay, I have two formulas.

=IF(ABS($A$2-Sheet2!A2)<=0.5,Sheet2!C2,"")

=VLOOKUP(A2,Sheet2!$A$2:$C$546,3,FALSE)

How do I combine them to get the desired result? Basically I want to know if each event in sheet 1 column A occurred within 12 hours of any event in Sheet 2 column A, if so then I want the corresponding value in sheet 2 column C (I said column A in my original post).

Try this formula in B2 copied down

=INDEX(Sheet2!C$2:C$546,MATCH(TRUE,INDEX(ABS(A2-Sheet2!A$2:A$546)<=0.5,0),0))

It worked like a charm. Thanks!
