Let SAS Help You Plan Your Next Holiday

It is possible to use SAS to calculate which date a national holiday is on in a given year.

The HOLIDAY function will return the SAS date of a common holiday. This means that we could do comparisons with these dates and work out whether a certain national holiday has passed, or is yet to happen.

The first argument should be a character value which is the name of the holiday you're investigating. The second argument is the year of interest - this has to be a numeric value.

The value returned will be a SAS date value.

Below is an example of some dates for the 2014 diary:

data holidays;
 year=2014;
 valentines = holiday('valentines', year);
 easter = holiday('easter', year);
 halloween = holiday('halloween', year);
 christmas = holiday('christmas', year);
 format valentines easter halloween christmas weekdatx.;
 put "Valentine's Day " year "is " valentines;
 put "Easter Day " year "is " easter;
 put "Halloween " year "is " halloween;
 put "Christmas Day " year "is " christmas;
run;

SAS Log:

Valentine's Day 2014 is Friday, 14 February 2014
Easter Day 2014 is Sunday, 20 April 2014
Halloween 2014 is Friday, 31 October 2014
Christmas Day 2014 is Thursday, 25 December 2014

Note that some dates will be returned as the U.S/Canadian version, but there are numerous holidays which apply to the rest of the world also.
