You do this by assigning the proper format (daily, weekly, monthly) to the variable date.

proc summary data=have nway;
    class date; /* Date has previously been assigned a date format */
    var sim;
    output out=_daily_stats_ median=/autoname;
run;
proc summary data=have nway;
    class date;
    var sim;
    format date weeku6.; /* Weekly format */
    output out=_weekly_stats_ median=/autoname;
run;
proc summary data=have nway;
    class date;
    var sim;
    format date mmyy.; /* Monthly format */
    output out=_monthly_stats_ median=/autoname;
run;

I leave it as a homework assignment for you to figure out how to do this by year.
