Monthly percentage greater than a value
 

Hi all
I have a spreadsheet with nearly 19,000 rows of data. It contains turnaround times in hours for two years of laboratory data. Col J is the turnaround time in hours and Col D is sample date. I would like to work out monthly percentages of turnaround times 4 hours (which is the target TAT). Any help with this would be greatly appreciated.

Thanks
Eddie

Sorted this with a pivot table in the end. Thanks
