or any calendar you want?

or conduct analyses of, or based on, dates from:

e.g., to be able to analyze effects thatare functions of annual sporting event schedules?

Step 1: Create interval datasetsdata fyds fqds fmds;

do begin= '06APR1900'd to '05APR2100'd;if day(begin) eq 6 then do;

mbeg=month(begin);season=max(mbeg-3,(mbeg<4)*(mbeg+9));end=intnx('month', begin, 1, 'same')-1; output fmds;if mbeg eq 4 then do;

season=year(begin);end=intnx('year', begin, 1, 'same')-1; output fyds;

end;if mbeg in (4,7,10,1) then do;

season=max(round(mbeg/4,1),(mbeg<4)*4);end=intnx('month', begin, 3, 'same')-1; output fqds;

end;end;

end;format begin end date.;

run;

Step 2: Apply the intervalds System Option

options intervalds=(FiscalQuarter=FQDS FiscalMonth=FMDS                     FiscalYear=FYDS);

Step 3: Use any desired interval function(s)data want (keep=date fiscal:);

set sashelp.pricedata (obs=12);format date date9.;fiscal_year=intindex( 'FiscalYear', date );fiscal_qtr=intindex( 'FiscalQuarter', date );fiscal_month=intindex( 'FiscalMonth', date );next_year_start=intnx('FiscalYear',date,1,'b');next_year_middle=intnx('FiscalYear',date,1,'m');next_year_end=intnx('FiscalYear',date,1,'e');format date next: date9.;

run;/*Note: You can also use other interval functions*/

which will produce: fiscal fiscal fiscal_ next_year next_year next_year date _year _qtr month _start _middle _end01JAN98 1997 3 9 06APR98 05OCT98 05APR9901FEB98 1997 4 10 06APR98 05OCT98 05APR9901MAR98 1997 4 11 06APR98 05OCT98 05APR9901APR98 1997 4 12 06APR98 05OCT98 05APR9901MAY98 1998 1 1 06APR99 05OCT99 05APR0001JUN98 1998 1 2 06APR99 05OCT99 05APR0001JUL98 1998 1 3 06APR99 05OCT99 05APR0001AUG98 1998 2 4 06APR99 05OCT99 05APR0001SEP98 1998 2 5 06APR99 05OCT99 05APR0001OCT98 1998 2 6 06APR99 05OCT99 05APR0001NOV98 1998 3 7 06APR99 05OCT99 05APR0001DEC98 1998 3 8 06APR99 05OCT99 05APR00

hardest part is creating the interval datasetsour paper includes code that creates datasets for:

the datasets can be transferred to Google Calendar with the code in Bill Roehl’s paper, Using SAS® to Get a Date: Integrating Google Calendar’s API with SAS®

www.sascommunity.org/wiki/Sometimes_One_Needs_an_Option_with_Unusual_Dates

All of the code and this Powerpoint can be found at:

create functions using PROC FCMP

import data from web sitescreate and use INTERVALDS datasets

The code includes examples of how to:

automatically create formats from data files

use the hash method to create lookup tables

create and send holiday email greetingswrite an expanded/localized Holiday function
