Previous month end datetime

[Analyticguru_09]

How to create a macrovariable which holds the value of previousmonth end date time

For ex: '8/30/2011 23:59:59'

[FriedEgg · Accepted solution]

proc format;

picture mydtfmt

other = '%m/%d/%Y %H:%M:%S' (datatype=datetime);

run;

data _null_;

/* get first day of current month */

today=today();

first_day=mdy(month(today),1,year(today));

/* get last day of previous month and add time 23:59:59 */

want_d=first_day-1;

want_dt=dhms(want_d,23,59,59);

/* put calculated datetime into macrovariable with for m/d/Y H:M:S */

call symput('previousmonth',put(want_dt,mydtfmt.));

run;

%put &previousmonth;

or, a bit easier:

data _null_;

  call symput('prev_month_end',intnx('dtmonth', datetime(),-1,'E'));

run;
