Subject: [TUHS] Re: When did "man cal" lose the comment about 1752?
My instance of cal (MacOS 14.5) has this in the man page:
-s country_code
Assume the switch from Julian to Gregorian Calendar at the date
associated with the country_code. If not specified, ncal tries
to guess the switch date from the local environment or falls back
to September 2, 1752. This was when Great Britain and her
colonies switched to the Gregorian Calendar.
That's 'ncal' from FreeBSD, which is an entirely "new"
implementation
written by Wolfgang Helbig:
commit 0cb2e609d9c2f0ceaf730a57ac5c11580058e7f4
Author: Wolfgang Helbig <helbig(a)FreeBSD.org>
Date: Mon Dec 15 20:35:22 1997 +0000
Add new command ncal.
Note that the switch to the Gregorian calendar
happened at different times
in different countries. In Catholic-dominated countries it happened in
October of 1582. The English-speaking world, being Protestant-dominated,
waited until September of 1752 to adopt it.
Indeed!
