Are you just interested in matching by the date only or does time come into the decisiom?
If the former then the most popular method of handling this type of multiple conditions is to create a helper column that concatenates the conditional fields you're interested in
For instance in Q2 copied down enter
Then in C2 copied down
repeat the Vlookup for the other columns changing the offset column number 7.
There was a strange anomaly when I opened the workbook with my UK regional settings. the column S Dates are pukka date numbers but the Column A dates were still text. i.e. S was UK style format dd/mm/yyyy whereas A was mm/dd/yyyy. Hence until I changed column A to values I didn't seen any matches. I guess that probably won't be a problem for you since presumably your Regional setting will be in in US format.
