Which toolboxes do you have available? I see autocorrelation functions available in at least DSP and Econ.

To determine the appropriate lag, you are going to need to specify how you want to deal with the irregular number of days in a month and the fact that the two 6 month periods are of different length (have to be, as there is an odd number of days in a year.)
