What day were you born? If you were born on September 23, 1962, type this command to get a calendar for the month:
%cal 9 1962
September 1962 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
You were born on a Sunday. Be sure to type all four digits of the year. If you don't, you'll get the calendar for 62 A.D.-almost 2000 years ago!
To get a calendar for the current month, just type cal (no arguments). You can also get the whole calendar for any year by giving a single argument: the year you want (use all four digits for any year in the last millennium).
There seems to be a bug in September 1752:
%cal 9 1752
September 1752 Su Mo Tu We Th Fr Sa 1 2 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
But there isn't really a bug. That's when Great Britain and the (then) American colonies adopted the Gregorian calendar; what would have been September 3 became September 14, and the beginning of the year changed from March 25 to January 1. Hmmmph. Bugs - in UNIX?
