Date calculations in SAS

Question

I want to add 1 day to an arbitrary SAS date. I have the following code that works but I wonder wether there is built-in support for date calculations like this:

<         


        

Answer 1

Itzy is right... just add 1. If you want to do more advanced date calculations you can use the intnx() and intck() functions.

e.g.

data _null_;
  tomorrow            = date() + 1;
  same_day_next_month = intnx('month',date(),1,'same');
  first_day_next_week = intnx('week' ,date(),1,'beginning');
  last_day_of_year    = intnx('year' ,date(),0,'end');

  put _all_; 
run;
