Birthdays: some show up, some don’t

[alexanderdd]

Steps to reproduce

We have a shared address book and enter birthday dates via the date picker.

Expected behaviour

all birthdays show up

Actual behaviour

Some birthdays show up in the birthday calendar, some don’t.
For the contacts whose birthdays don’t show up in calendar, it does not even help to change their birthday in the contacts webinterface nor in Thunderbird Cardbook. They just won’t show up at all.

I downloaded the birthday calendar as calDAV and looked for differences:

Birthdays that show up as expected
all the examples I saw were VERSION:3.0
some were PRODID;VALUE=TEXT:-//Thunderbird.net/NONSGML Thunderbird CardBook V37.6//DE
some were PRODID:-//Sabre//Sabre VObject 4.1.6//EN

Birthdays that don't show up as expected
some were VERSION:4.0
some were VERSION:3.0
some were PRODID:-//Nextcloud Contacts v3.5.1
some were PRODID:-//Sabre//Sabre VObject 4.1.6//EN

Calendar app

Calendar app version: Calendar 3.0.2

Client configuration

Browser: Firefox 96.0.1

Server configuration

Any ideas? Any other info you need?

I'll just say that I have lots of contacts with birthdays, but when i go to the contact birthday calendar, it is completely empty. Downloading the contact birthday calendar data creates a calendar file with no records.

When I go to my contacts, I do see the birthdays there.

Did you reimport contacts before you faced the issue? I can reproduce the following:

1. Create birthday calendar.
2. Import vcard contact. Contact and birthday show up correctly.
3. Delete contact.
4. Reimport vcard contact. The reimport finishes with "1 error". The contact shows up, the birthday does not.

The issue can be "resolved" by emptying the calendar trash can.

This seems, however, like a bug in nextcloud/server. Likely in server/apps/dav/lib/CalDAV/BirthdayService.php.
As far as I understand, the birthday event cannot be recreated because a deleted entry with the same UID already exists in the database.

I opened a PR in nextcloud/server for the reimport issue. Let me know if that solves your problem. Otherwise, reproduction steps may help.

@szaimen please reopen.

No there were no reimports.

I can reproduce the situation described in my first comment, but I guess you cant reproduce it on your test server...

Let me know what else you need from me.

[apotek]

I didn't realize this issue was specific to reimporting.

My issue is simply that birthdays don't show up in the calendar at all.

I can create a contact in nextcloud, give that contact a birthday ( say, April 1, 1970), and hey, April Fool's! When you go to April 1 in the calendar view, you will not see that birthday.

I can create a contact in the Contacts app in Mac OS. Assign a birthday. Let that contact sync. Go to that contact's date in the nextcloud birthday calendar and.... (drumroll please), no birthday on that date.

I can create a contact in my android contacts app. Assign a birthday. Let that sync. Go to that contact's date in the nextcloud birthday calendar and.....(canned audience laughter) ... no birthday on that date.

This used to work. But for the last several versions of nextcloud it does not.

If there is another thread that is for my issue, I'll take my comments there. I didn't mean to squat on a calendar import issue :)

[alexanderdd]

@apotek your issue seems to be different from mine (see my first post. No it's not about reimporting.) - please open a separate issue for your problem.

@ChristophWurst can you collapse all comments by @apotek and @max65482 ? They are not related to my issue.

Again: tell me if you need more info.

[max65482]

As I already mentioned, reproduction steps (1., 2., ...) may help. Preferably based on a blank NC instance and with all relevant materials attached.

In my case all the contacts' birthdays have disappeared from the calendar but are still in the address book.

The only thing I have done recently was to update Nextcloud to version 22.2.5. I cannot tell if this situation was present in the previous version.

When I export the calendar I only get the following:

BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
PRODID:-//SabreDAV//SabreDAV//EN
X-WR-CALNAME:Contact birthdays
X-APPLE-CALENDAR-COLOR:#e9d859
REFRESH-INTERVAL;VALUE=DURATION:PT4H
X-PUBLISHED-TTL:PT4H
END:VCALENDAR

[max65482]

I cannot reproduce this.
Can you share the export of one contact (redacted)? This should be a .vcf file.

@max65482 I stripped a lot of personal information that I don't know if it makes some conflict. I left the "name" and birthday.
