How to list dates defined by a data validation process

On a separate matter, you're only looking at the max temperatures - wouldn't you prefer to see opportunities when both max and min temperatures are in range (even if you do have to tweak that range a bit if your seasonal temperatures don't allow you to apply the stuff at all)?

Yes. Currently I am only looking at the max temps because its late Summer early Autumn here, (just trialling this concept), but you are right, later on when the temps fall the Minimums will be a deciding factor.
