Birthday without birthyear

[tobiasKaminsky]

From nextcloud/calendar#842: should be opened on server.

Some apps, e.g. contacts on samsung allow to store the birthday without birthyear (in case you do not know how old somebody is).
These contacts are synced fine to NC, but the dates are not shown in the birthday calendar.
Those dates should be shown, e.g. with in a given date range (1970-2030).

Duplicate of #4287 - please read what others write 😉

Also ref #3084

[tobiasKaminsky]

Well, #4287 states that these dates are not synced, which in my case is not true, as they are synced.
#3084 says that they are shown with *1604, which is also not true in my case.

In my case those fields get synced to NC server, but the "birthday calendar" does not use the date and thus no calendar event is shown.

This is how Apple sets it.

Ah - okay, but then #4287 seems to be fixed, or am I wrong?

I'm not aware that #4287 was fixed yet.

@tobiasKaminsky Can you please create a dummy contact, add a birthday without year, export it and post it here? :)

Well, #4287 states that these dates are not synced, which in my case is not true, as they are synced.

The problem is that these dates are synced but removed (or removed and synced) and lost forever.
The operative keyword here is lost forever.

@georgehrke unfortunately it still hasn't been fixed. I lost all my bithdays w/o a year and I then started to use the notes field for birthdays w/o a year.

@georgehrke this is a contact synced from Samsung S9 (with their default contacts app) via davdroid to a NC server (server & contacs on master branch):

The corresponding birthday calendar is this

This is shown correctly on Thunderbird, but not on Samsung S9 nor on OnePlus3.

[rfc2822]

@tobiasKaminsky Android can't process recurring events starting before 1902 because of 32-bit limitations. The given event starts in 1900.

[georgehrke]

Ok, so one work around I can imagine here:
Inside the BirthdayEventGenerator, check if the property X-APPLE-OMIT-YEAR equals the actually used year, if yes generate events without a year starting in 1970.

[tobiasKaminsky]

@georgehrke
I would assume that always 1604 is used, so it should be checked agaist 1604 and not against the actually used year.
And then it should be sufficient to use something after 1902 as starting year.

If you can create a patch, I am happy to test it :-)

@georgehrke I might have been wrong with my last comment that it hasn't been fixed yet.

Well, at least the data loss has been fixed. I just entered a birthday without a year (June, 20th) on my Google Pixel and it was synced to my nextcloud (12.0.9) as:

BDAY:--0620

Behold, even after a few times syncing, the field is still there. Yippiiee!!!!!!

The Contacts app shows this birthday 1604-06-20, which is a bit weird, since the vcard does not contain X-APPLE-OMIT-YEAR.

I believe this now has to be followed up in the contacts issue tracker to

• correctly show vcard fields that look like BDAY:--0620 and BDAY;X-APPLE-OMIT-YEAR=1604:1604-06-20
• allow to enter a birthday without a year in the date picker

[tobiasKaminsky]

@georgehrke any news here? Can I help you with something?

[tobiasKaminsky]

@georgehrke maybe we can talk about this on hackweek? :-)
