SYNTAX
      cal [-jy] [[month] year]
options:
     -j      Display julian dates (days one-based, numbered from January 1).
     -y      Display a calendar for the current year.
    A single parameter specifies the 4 digit year (1 - 9999) to be displayed.
    The year must be fully specified: `cal 89' will not display a calendar
    for 1989.
    Two parameters denote the month (1 - 12) and year.
    
    If no parameters are specified, the current month's calendar is displayed.
