     CAL(1)                                                     CAL(1)

          cal - print calendar

          cal [ month ] year

          Cal prints a calendar for the specified year.  If a month is
          also specified, a calendar just for that month is printed.
          Year can be between 1 and 9999.  The month is a number
          between 1 and 12.  The calendar produced is that for England
          and her colonies.

          Try September 1752.

          The year is always considered to start in January even
          though this is historically naive.
          Beware that `cal 78' refers to the early Christian era, not
          the 20th century.
