Date: Thu, 14 May 2015 21:20:21 -0700	[thread overview]
Message-ID: <CAAgRMMJf39b5G6Q+4w=F8c8Wpw9R63frENQtg8tpFFHbgkmCmA@mail.gmail.com> (raw)

Hi Bug Emacs,

Why does (calendar-absolute-from-gregorian '(10 10 1582))
return 577731?
(calendar-generate '(10 1582)) is another example of this
error.

There are no Gregorian dates from 5 - 15 October 1582.
Pope Gregory declared this.

Hence, ALL absolute day numbers in calendar before 1582
are probably wrong. So using emacs for historical computations
is bogus.

I will work on writing calendar-absolute-from-gregorian and
calendar-gregorian-from-absolute to patch this error.

Let me know if this sounds OK.
