quick calendar on Mac OS X

Mac OS X has built in calendar application named iCal but you may want to peek at certain days/date quickly rather than spawning a full fledged application. Well this is possible with command line option on mac.

Entering command cal jan 2012, on terminal window, will show the calendar for month Jan 2012:

Calendar for Jan 2012

To see the calendar for entire year just type: cal 2012
