Initial occurence of 'diary-anniversary' in calendar

Initial occurence of 'diary-anniversary' in calendar

[Ulf Jasper]

Anniversary entries like

    %%(diary-anniversary 4 4 2016) Mark My Diary

will show up in the calendar only from 4 4 2017 on, i.e. one year after
the actual event.  The initial occurrence of an anniversary (4 4 2016)
does not get marked in the calendar.  Why is that?

(Changing this behaviour would fix bug#23100 which results from that
fact that icalendar.el considers 'diary-anniversary' to be equivalent to
a YEARLY ical event.)

Making the initial occurrence of an anniversary show up seems natural to
me.  So I would like to implement that.  But maybe I am missing
something here.  Am I?

Best,
Ulf

The first anniversary is one year after the event.

Agreed.  That is also what my dictionary tells me.  And the Emacs manual
says the same:

|      %%(diary-anniversary 10 31 1988) Arthur's birthday
| 
| This entry applies to October 31 in any year after 1988; 

But still I would expect to see Arthur's actual birthday marked in the
calendar.

Best,
Ulf
