In my Excel file i have over 1000 rows of data. This contains temperatures
measured each minute for each hour for each day over a month. Yes i know
that's a lot of data!

I want to be able to get an average hourly temperature for each hour of the
day as a way to simplify my spreadsheet. So basically what i want to do is
average the temperatures recorded between 9:00am and 9:59am for 9/3/2009, and
do the same thing for each hour of that day as well as every other day.

Is there a macro or something i can use to speed things up? I have tried
doing it the long way and it is of course pain-stakingly slow - in which case
i thought to myself there must be an easier and quicker way to do this!

Can anyone be able to help me?

Thanks,
