Hello! Any news here?
Is this still happening?

This is also happening to me. There's not much more to add I think except it still happens in the latest release.

This is the card generated by Nextcloud when I press download:

BEGIN:VCARD
VERSION:3.0
PRODID:-//Sabre//Sabre VObject 4.1.6//EN
UID:e9e0cc90-6926-4d07-b3a9-674383cab715
FN:James Cole
N:Cole;James;;;
BDAY:20160126T000007
END:VCARD

Check out the time added to the birthday.

Manually editing the card to BDAY:20160126 in the database fixes this issue. My uninformed guess is that the time selector on the birthday field is messing things up.

I also ended up with this card somehow:

BEGIN:VCARD
VERSION:3.0
FN:112
N:;112;;;
TEL;TYPE="WORK,VOICE":112
ITEM1.ORG:Alarmcentrale
NOTE:112 Alarmcentrale
UID:41893e41-0cb1-4877-af93-645f07800e5c

CATEGORIES:Bedrijven
BDAY;VALUE=DATE-AND-OR-TIME:2019-02-02T21:10:31
END:VCARD

And yes I have a card for the emergency number. 😋

Still the same after update! No birthday entries in IOS.

iOS can only show birthdays without time. In v-card or with synching time is transmitted unless it is 00:00. So you just have to manually take away any different time than 00:00. Had the same issue for a long time but the perfect solution would of course be if it was corrected on nextcloud web service.

[Concific]

I tried it and It doesn´t matter if the time is 00:00 or different. No sync to IOS.

[beinaendi]

In my case it does matter and by the way the birthdays are always synced. I can see birthdays in iPhone's birthday calendar always, but they are only displayed in contact details when they are with time 00:00. Can you see them in your birthday calendar if you activate it?
