how to stack monthly(hist)

Hi

I have time series. I want to stack monthly(hist). I need to count how many times my time series repeated in every month for given long period and stack each month results. January+January, February+February, March+March..... Such as January would be repeated 250, February 300, March 280.......

(Please see attached excel file).

Thanks a lot!

[~,~,c] = xlsread('stack_monthly.xlsx');
[y,m] = datevec(c,'yyyy-mm-ddTHH:MM:SS.FFFZ');
a = unique([y,m],'rows');
out = accumarray(a(:,2),1);
