Chapter 5: The CALENDAR Procedure
Overview: CALENDAR Procedure
What Does the CALENDAR Procedure Do?
The CALENDAR procedure displays data from a SAS data set in a monthly calendar format. You can produce a schedule calendar , which schedules events around holidays and nonwork periods, or you can produce a summary calendar , which summarizes data and displays only one-day events and holidays. When you use PROC CALENDAR you can
-
schedule work around holidays and other nonwork periods
-
display holidays
-
process data about multiple calendars in a single step and print them in a separate, mixed, or combined format
-
apply different holidays, weekly work schedules, and daily work shifts to multiple calendars in a single PROC step
-
produce a mean and a sum for variables based on either the number of days in a month or the number of observations.
PROC CALENDAR also contains features that are specifically designed to work with PROC CPM in SAS/OR software, a project management scheduling tool.
What Types of Calendars Can PROC CALENDAR Produce?
Simple Schedule Calendar
Output 5.1 illustrates the simplest kind of schedule calendar that you can produce. This calendar output displays activities that are planned by a banking executive. The following statements produce Output 5.1.

This calendar uses one of the two default calendars, the 24- hour -day, 7-day-week calendar.

Simple Summary Calendar
Output 5.3 shows a simple summary calendar that displays the number of meals served daily in a hospital cafeteria:
options nodate pageno=1 linesize=132 pagesize=60; proc calendar data=meals; start date; sum brkfst lunch dinner; mean brkfst lunch dinner; run;
In a summary calendar, each piece of information for a given day is the value of a variable for that day. The variables can be either numeric or character, and you can format them as necessary. You can use the SUM and MEAN options to calculate sums and means for any numeric variables. These statistics appear in a box below the calendar, as shown in Output 5.3. The data set that is shown in this calendar is created in Example 7 on page 143.

Advanced Scheduling and Project Management Tasks
For more complex scheduling tasks, consider using the CPM procedure in SAS/OR software. PROC CALENDAR requires that you specify the starting date of each activity. When the beginning of one task depends on the completion of others and a date slips in a schedule, recalculating the schedule can be time-consuming . Instead of manually recalculating dates, you can use PROC CPM to calculate dates for project activities based on an initial starting date, activity durations, and which tasks are identified as successors to others. For an example, see Example 6 on page 137.
