US working days

Hi,

How can I get the US working days starting 1997 in matlab ?

I don't think there is any simple way to do this within core MATLAB (where by "simple" I do not include coding the algorithm yourself). A cursory search of the FEX also did not turn anything up.

Do you have the Financial Toolbox at your disposal? Scanning the function list here: http://www.mathworks.com/help/toolbox/finance/f6-213137.html#f0-222567, it looks it might have what you need.

Here you find the federal holidays for 1997 to 2020:

I do not see a more efficient way than counting them manually and subtract them from the number of Monday to Friday per year:

for year = 1997:2020
  Jan01 = datenum(sprintf('01-Jan-%04d', year));
  Dec31 = datenum(sprintf('31-Dec-%04d', year));
  w = mod((Jan01:Dec31) - 2, 7) + 1;  % 1=Sun, 7=Sat
  s = sum(q > 1 & q < 7);
  fprintf('%d: %d\n', year, s);
end

There's a small typo in the line where you define w ("Dez31" instead of "Dec31").

@Cyclist: Fixed. Thanks.
