Synopsis

cal [options] [month [year]]

The cal command prints a calendar—by default, the current month:

$ cal
   December 2011
Su Mo Tu We Th Fr Sa
             1  2  3
 4  5  6  7  8  9 10
11 12 13 14 15 16 17
18 19 20 21 22 23 24
25 26 27 28 29 30 31

To print a different calendar, supply a month and four-digit year: cal 8 2011. If you omit the month (cal 2011), the entire year is printed.

Useful options

-y	Print the current year’s calendar.
-3	Three-month view: print the previous and next month as well.
-j	Number each day by its position in the year; in our example, September 1 would be displayed as 244, September 2 as 245, and so on.
