I thought the list might want to see the resolution to my issue. I wanted to
calculate the different between two times but wanted to drop the time on
weekends and holidays. Here is the syntax that works. I received several
helpful e-mails from the list although the syntax below was a variation of
Raynald's syntax. Thanks to all!
data list / date1 1-20 (DATETIME20) date2 22-41 (DATETIME20) .
18-JAN-2005 23:59:00 20-JAN-2005 00:01:00
01-JAN-2005 11:59:00 31-JAN-2005 18:00:00
15-DEC-2004 00:01:00 05-JAN-2005 23:59:00
04-JAN-2005 11:25:00 10-JAN-2005 12:35:00
01-JAN-2004 18:00:00 06-JAN-2004 18:00:00
25-DEC-2004 19:42:31 20-JAN-2005 14:34:25
*Just a baseline normal number of days* .
COMPUTE DAYS =CTIME.DAYS(date2-date1).
*Note dates are stored in seconds, 86400 per day*.
*Calculate the time until midnight on admitdate if it is not a weekend or
If RANGE(XDATE.WKDAY(date1),2,6) & ~ANY(XDATE.DATE(date1),
*Calculate the time since midnight on releasdate if it is not a weekend or
IF RANGE(XDATE.WKDAY(date2),2,6) &~ANY(XDATE.DATE(date2) ,
*Calculate the number of full days in between the admit and release date
that are not
holidays or weekends*.
LOOP #=(date1 + GAP1) to (date2 - ( 86400 + GAP2 )) BY 86400.
IF RANGE(XDATE.WKDAY(#),2,6) &~ANY(XDATE.DATE(#) ,
