September 1752 only had 19 Days

Doing some scripting today and looking at the manpage for the Unix program cal and saw this note:

An unusual calendar is printed for September 1752. That is the month 11 days were skipped to make up for lack of leap year adjustments.
I had never heard that, but sure enough, if you use the cal program for September 1752:
September 1752
S M Tu W Th F S
1 2 14 15 16
17 18 19 20 21 22 23
24 25 26 27 28 29 30
This will give me a new thing to check when I'm looking at a calendaring tool or playing with some gadget/widget. Anything that displays a full month for September, 1752 will get a bad mark.
