bug#54756: 28.1; faulty date interpretation

[Peter Dyballa]

Hello!

I think it's close to impossible to reproduce the bug when launching GNU Emacs with -Q, because dates in diary file are read and they must be interpreted the proper way, the European and natural way, as day - month - year (or in reverse):

%%(diary-anniversary  4  6 1862) Geburt von Karl Valentin in München-Au als Valentin Ludwig Fey %d Jahren
%%(diary-anniversary  4  6 2020) Tod von Rupert Neville Hine

Today all my versions of GNU Emacs 28.x report that it's the birth date of Karl Valentin and the death date of Rupert Hine:

	Sunrise 06 Uhr 53, sunset 20 Uhr 04 at Friedberg (13:11 hrs daylight)
	Geburt von Karl Valentin in München-Au als Valentin Ludwig Fey 160 Jahren
	Tod von Rupert Neville Hine

The versions 27.x display that today's date (probably) was not much meaningful for the two men.

It isn't pollution that's harming the environment. It's the impurities in our air and water that are doing it.

I'm not sure I understand what you mean here, but perhaps I'm not
reproducing the problem correctly.

If I put the following inn ~/.emacs.d/diary, and then start Emacs 27.1
with -Q, and then say `M-x diary':

%%(diary-anniversary  4  7 1862) Geburt von Karl Valentin in München-Au als Valentin Ludwig Fey %d Jahren
%%(diary-anniversary  4  7 2020) Tod von Rupert Neville Hine

I get

I get exactly the same in Emacs 28.1.

I never use diary, so I don't know whether this is what's expected or
not.  Could you explain what you expected to see here, or whether you're
seeing something else in Emacs 28.1?

That's not surprising, since you put the date in US American notation into diary.

In GNU Emacs 27 and before it worked to switch to European date format:

	/Library/Application Support/Emacs/site-init.el:23:(defvar european-calendar-style t)
	/Library/Application Support/Emacs/site-init.el:72:(setq european-calendar-style t)

which now does not get loaded, as *Messages* shows:

	/Library/Application Support/Emacs/site-start.el:165:;(calendar-set-date-style 'european)
 
I'd presume that dumping is a problem:

	Warning: Change in load-path due to site-init will be lost after dumping

which I better should avoid:

	calendar-date-style is a variable defined in ‘calendar.el’.
	
	Its value is ‘american’


Activating "(setq calendar-date-style 'european)" brings:

	calendar-date-style is a variable defined in ‘calendar.el’.
	
	Its value is ‘european’
	Original value was ‘american’

Now I get in *Fancy Diary Entries* only:

	Sunrise 06 Uhr 50, sunset 20 Uhr 05 at Friedberg (13:15 hrs daylight)

and on 4. of June:

	Sunrise 05 Uhr 19, sunset 21 Uhr 28 at Friedberg (16:08 hrs daylight)
	Geburt von Karl Valentin in München-Au als Valentin Ludwig Fey 160 Jahren
	Tod von Rupert Neville Hine

So it's more my bug - sorry!

OK; closing this bug report, then.
