Formula To Average Range Of Cells And Copying It To Calculate Next Range Of Cells?

I have a row data corresponding to the measuring of load cell per min and I need to average the values per hour. So I have a column B for the date (from 1-01-2013 to 31-01-2013, column C for the time (0:00:00 to 23:59:00), and D de values per min I want to average. I have to do the same for the rest of the month of 2013 (February, ...., December).

I would like to know if there is a way to create a formula to calculate the average of the first 60 values (to get the average of the first hour of 1-01-2013), and then copy it to get the average of the following 60 (average of the second hour in 1-01-2013) and so on.

If there is no way to do it, I would like to know if I can do it using functions like average, match, index, offset, what would be the best match of those functions.

I also tried it by doing the analysis in another tab and using the function "averageifs" with two criterias: one for the date (example 01-01-2013) and another one for the hour (example 0:00:00), but it didnt work, it show error: #value. I inserted an extra column in the data tab with just the hour (example 0:00:00) in front of the corresponding column with (example 0:01:00, 00:02:00, etc)
Equation I used for this:

=AVERAGEIFS('Data (min)'!D$6:D$43206,'Data (min)'!$A$6:$A$44646,A6,'Data (min)'!$B$6:$B$44646,B6)
=AVERAGEIFS(TAB AND COLUMN WHERE THE RAW DATA IS,RANGE OF CRITERIA 1,CRITERIA 1,RANGE CRITERIA 2,CRITERIA 2)
