Does the interesting output of cal, when called for september 1752, deserve mentioning? It is:

$ 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


The situation is related with leap year issue.

cal 9 1752

[edit]

cal 9 1752 _does_ deserve mention as it has a very interesting story. it isn't related to leap-year at all, but rather has to do with a bug in the original cal code. Instead of fixing the copies of code that had been already distributed, representatives from AT&T convinced the vatican to remove those days from history.

lol, very funny! But I'd better put in a warning that this isn't true, just incase anybody should think that.... :o

Julian

[edit]

While we are on 1752 shouldn't the Julian calendar be mentioned too? Mathmo 10:07, 28 March 2006 (UTC)[reply]

cal sep 1725

[edit]

The Article states, The Plan 9 from Bell Labs manual states: "Try cal sep 1752."

Does this need a correction? "cal 9 1752" would work, "cal sep 1752" does not. Mikepegg (talk) 15:06, 24 June 2009 (UTC)[reply]


"cal sep 1752" and "cal 9 1752" work in the version of cal available now, but i do not have an older version to test it with —Preceding unsigned comment added by 80.42.171.143 (talk) 00:44, 6 August 2009 (UTC)[reply]


"cal sep 1752" is not accepted by any of Fedora Core 12, Cygwin, or SunOS 5.9. The first two make the value judgement,

"cal: illegal month value: use 1-12"

while the third adopts a more scolding tone:

"cal: bad month
usage: cal [ [month] year ]"

Guys, Plan 9 is actually not Unix at all; it resembles Unix in some ways, but it's not Unix... AnonMoos (talk) 19:40, 18 April 2012 (UTC)[reply]
