Hi Doug,
Sorry I am new here and haven't got the faintest idea how to attach data or anything but I've copied A38:E54 below, hope it works...

=SUMPRODUCT(--(MONTH($A$2:$A$73)=3),--($E$2:$E$73>=0.5))
This returns a count of 2 for all Marchs (column A) with +0.5 or above (column E). I've coloured the actual cells calculated in red
Now I want to use the same formula as above ^ but instead of returning a simple count I want it to SUM the values in column D based on the above criteria. So I need another new formula for this.
So for all March values >=0.5, it would return the number 31 (D40+D52). I've coloured these green
Furthermore, I also want to use the same criteria (March and +0.5 or above) but instead of counting (first example) or summing (second example) I want to average the length (column B) for the cells meeting the criteria. SO I need another new formula for this as well.
So for all March values >=0.5, it would return the number 4.20437056 (mean of B40 and B52). I've highlighted these in purple
I want the formulas to be fairly easy to change up where needed, so if I wanted a different month or a different >= value etc.
Thanks in advance and apologies if I've made an easy task of copying data here difficult!
