@rfc2822 I extended my server to speak VCard 4.0 and wanted to test this with Davdroid. So I stumbled on that problem. It will soon be available.
I’m not an android developer, but it should support dates without year. If I sync my contacts with google the year is optional.
Also I saw the property yearOptional in the Davdroid source code.
VCard 4.0 does support dates without year in the rfc 6350, the ezvcard-library has a getPartialDate() function, that supports dates without year.
Seems like for format is really “–mm-dd”:
// No year format is not supported by Exchange.
mockNameValues.put(Event.START_DATE, "--06-01");
mockNameValues.put(Event.TYPE, Event.TYPE_BIRTHDAY);
oldState.addEntry(ValuesDelta.fromAfter(mockNameValues));
mockNameValues = new ContentValues();
mockNameValues.put(Data.MIMETYPE, Event.CONTENT_ITEM_TYPE);
mockNameValues.put(Event.START_DATE, "1980-08-02");
// Anniversary is not supported by Exchange
mockNameValues.put(Event.TYPE, Event.TYPE_ANNIVERSARY);
oldState.addEntry(ValuesDelta.fromAfter(mockNameValues));
So this should be possible.
Should be implemented by vcard4android/0cb821c7 and davdroid/fab9dbaf, but needs some real-life testing. Could you do that?
You are really fast.
One thing you should notice is that PartialDate is not working with VCard 3.0, because in 3.0 the date must have a year. Ezvcard will throw an exception.
I will test it on friday.
@jofrax said in Birthdays without year:
One thing you should notice is that PartialDate is not working with VCard 3.0, because in 3.0 the date must have a year. Ezvcard will throw an exception.
In my tests, it just doesn’t output a BDAY in VCard/3 when there’s only a partial date.
I did some tests with the server and got NullPointerExceptions. I fixed this in your code and will make a MergeRequest.
For VCard 3.0 I set the year in your code to 1900, if there was no year - otherwise you cannot save the birthday. Maybe you can set a VCard property - apple makes it this way (BDAY;X-APPLE-OMIT-YEAR=1604:1604-08-14), but the server must understand this.
Seems I’m not allowed to make MergeRequests on your project!
I forked the project to https://gitlab.com/jofrax/vcard4android and changed 3 files. Everything (VCard 3.0, 4.0, with and without year) is working for me so far.
@jofrax Can you please post a patch here for the latest vcard4android?
And I’ll still have to find a server which I can use to test, I’ll try with Nextcloud

vcard.setBirthday runs into an exception, if vcard version is 3.0 and the birthday contains a PartialDate.
@jofrax Are you sure that it throws an exception? Which kind of exception? In my tests, there’s only a validation warning and ez-vcard just doesn’t output the BDAY, which seems to be the best solution in this case.
Hm. You’re right, but I’m sure, I got an exception - maybe it was in another version of ezvcard.
The vcard that is produced contains an empty BDAY.
VERSION:3.0
PRODID:ez-vcard 0.10.2
BDAY:
END:VCARD
```
I'm not sure, if an empty BDAY is allowed in rfc.
Also the given birthday will be lost completely when using VCard 3.0.
