DUR variable;

contains the duration of each activity in a schedule calendar.

Range:	The duration can be a real or integral value.
Restriction:	This variable must be in the activities data set.
See also:	For more information on activity durations, see Activities Data Set and Calendar Data Set

Duration is measured inclusively from the start of the activity (as given in the START variable). In the output, any activity that lasts part of a day is displayed as lasting a full day.
The INTERVAL= option in a PROC CALENDAR statement automatically sets the unit of the duration variable, depending on its own value as follows:

INTERVAL= Default Length of the Duration Unit

DAY (the default) 24 hours

WORKDAY 8 hours
You can override the default length of a duration unit by using
- the DAYLENGTH= option
- a D_LENGTH variable in the CALEDATA= data set.

INTERVAL=	Default Length of the Duration Unit
DAY (the default)	24 hours
WORKDAY	8 hours
