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 2012

If you omit the month (cal 2012), the entire year is printed. You must provide the full year number with four digits: cal 12 will print a calendar for the year 12 A.D.

Useful options

-y

Print the current year’s calendar.

-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.
