Date calculations

Date calculations

[Fredrik]

I'm using a normal org-file as my contact register so I easier can  
link tasks to a specific person. I have also added events as birthdays  
to each contact but is there some way I can make them show up in the  
agenda with some yearly calculations?

For example a simple birthday reminder can look like this:

* <2006-12-30 ++1y> Happy Birthday!

Is there some clever way I can add a date calculation to it when it  
shows up in the agenda?

* <2006-12-30 ++1y> Happy Birthday %d years!

Regards,

Fredrik

Re: Date calculations

Hmm reading a bit more in the manual I found that entries like this  
should work:
%%(diary-anniversary 14  5 1956) Arthur Dent is %d years old

But I can't make in show in my agenda?
The manual also samples this :
%%(org-calendar-holiday)
This works though? So any ideas on how to make the first one work?

Regards,

Fredrik

You can use diary sexps. Search the manual for "Diary-style sexp 
entries". As an example I have:

%%(diary-anniversary 3  1 2000) Ella is %d years old

in one of my org files.

I used to do it the way it was done in the manual:

(info "(org)Weekly/daily agenda")
under Calendar/Diary integration

     %%(diary-anniversary 14  5 1956) Arthur Dent is %d years old

I now use bbdb which also works good and has gnus integration which is
important to me.

I can't for the life of me get this to work.

I tried emacs 22.1, 22.3, emacs 23.1 and the current CVS head.

Additionally I tried a few combination of org 5.23a, 4.12a, the newest
git HEAD and others in between. I also changed the value of
`org-agenda-include-diary' and whether or not a ~/diary file existed.
(Zero-length though).

I remember that this worked. But not at the moment.

Does anyone have this working?

Works fine here.

%%(diary-anniversary 10 1 1960) Geburtstag xyz: %d Jahre.

Emacs 23.1.90.1

Hi Benjamin,

currently these lines must be all the way at the left margin, they  
cannot be indented.

I'm sorry for that line, it was ambiguous. I meant to indent it for
clarity, not to represent how it's indented in my file.

I have found the culprit though.

This works:
%%(diary-anniversary 12 30 1984) Arthur Dent is %d years
                     ^   ^   ^
                     M   D   Y
This doesn't:
%%(diary-anniversary 30 12 1984) Arthur Dent is %d years
                     ^   ^   ^
                     D   M   Y

This isn't affected by any locale setting on my end.

I tried en_GB, de_DE and en_US and it will always choose the US M/D/Y
format in the org-mode file. That runs counter to the documentation
example cited above, so does anyone else see that?

Second one is what I have here and it works as expected.

Probably related to these settings in my .emacs:

(setq european-calendar-style t)      ; obsolete!
(setq calendar-date-style 'european)  ;(info "(emacs)Date Formats")

Do you have these set, too?

Thanks! If I set it to european, it works.

Should the documentation be changed to the american default? (If it is a
default and not based on the $LANG when emacs is being built.)

Re: Re: Date calculations

Hi Benjamin,

can you point out exactly where in the documentation this is located?

Thanks.

P.S.  Emacs calendar is great, but changing function call arguments  
depending on calendar style was a truly braindead decision.....

Sure.

org-mode/doc/org.text
Line: 6643

I wouldn't know how to phrase it, but maybe a link to
(info "(emacs)Special Diary Entries") where this behaviour is explained
is the best.

     The entry looks like this:

     %%(diary-anniversary 10 31 1948) Arthur's birthday

     This entry applies to October 31 in any year after 1948; `10 31 1948'
     specifies the date.  (If you are using the European or ISO calendar
     style, the input order of month, day and year is different.)"

I completely agree. Or go all the way with localization and make the
`and' macro short-circuit right to left when you run the elisp in
Israel. ;-)

These examples suggest D-M-Y, which only seems to work with the calendar
set to european style. Maybe, it would be better to change the example
to M-D-Y (I think it is more common?) and add a footnote that provides
the info that the date format is depending on calendar-date-style?

The next paragraph (Anniversaries from BBDB) on the other hand states a 
fixed order.

So, if I understand it correctly, org-bbdb settled on iso format,
diary-anniversary uses either american or european style depending on
calendar-date-style. 

Thats somehow inconsistent, isn't it?

It might be even better to use calendar style ‘iso’ in that
documentation, to be consistent with default Org usage.

Yes, that inconsistency in the Diary behaviour has been noted.

Hi Memnon,


Org-mode consistently uses ISO format, I believe.  I chose it  
precisely in order
to make sure there could be no misunderstanding in what these dates  
mean.

I cannot change the behavior of the calendar functions....
