how to calculate the gap of working days between two columns ?

Marcate — Fri, 07 Oct 2016 19:04:59 GMT

I would like to calculate the working days interval between two columns of a working table.

The idea is to create a table that will use informations from two other tables as follow: one with the list of the holidays of the year and another that contains the dates that must be compared. How do I have to proceed?

I did it in two steps:

1) using table of non working dates - create a format (NWD.) with

each non working date translated to 0 and OTHER translated to 1.
Do it once, for the whole period of years including some future years.

2) calculate working days (WDS) from given dates: from FDT to UDT by:

WDS = 0;

do date = FTD to UDT;

WDS = WDS + input(put(date,NWD.),1.);

end;

SAS offers quite a few very useful calendar functions like intnx() and intck() which allows you get such calculations done.

If you have your own holiday calendar then you must first create a "custom interval" though. Have a look into the Custom Intervals section under the following link: http://www.sascommunity.org/wiki/Generating_Holiday_Lists
