Have a time series from 1 to 156. Want to extract the values from 1:6, then from (1+12) : (6+12), etc into a new variable. How to go about.

I don't know what format your dates are in but this can be adapted to any format. I assume your matrix is named 'data' and the dates are in the 5th column.
% Get the month number for each date
monthNum = month(data(:,5));
% Logical index of rows that are between May and October
monthIdx = ismember(monthNum, [5:10]);
% Extract your data for these months
data(monthIdx, :)
