Extracting certain months from an array

Hey. I have some 40x60x157800 arrays. 40x60 is values from measurements. 157800 measurements for every hours through 17 years. I have another array with datetime, and wants the months 5,6 and 7 in a different array. I have tried this:

 summermonths = A(:,:,month(dates)==5);

But then I only get one month at the time. How can I do?

Read about datevec. This splits your dates into years, months, days and time. From this you can get the index of the months you want.
