Our family has a bunch of people whose birthdays we need to keep track of. Those birthdays matter to everyone, so we would like to have one shared birthday calendar. The calendar should come with an android app that at least sends reminder notifications about birthdays.
What selfhosted solution are you using for this? What can you recommend?
Don’t host the calendar, just host some WebDAV/CalDAV. That format is support by basically all apps on every platform (usually including the default app on most phones), so everyone can pick what they want (or just stick with what they already use).
My personal pick for that prupose is Radicale.
There’s nothing to host.
Create an iCal file and import it into your calendar application on your phone.
I use Nextcloud to host my calanders. With caldav (what nextcloud uses under the hood), reminders are handled by the client. I use Apple’s Reminders app on my phone and Thunderbird on my laptop.
Nextcloud does have a built in calandering app, but I’ve not used it much. I think it can do email notifications of calander events.
There are a multitude of calendar apps, tho I know of none specifically for birthdays exclusively.
- Nextcloud AIO combined with Nextcloud Android app
- Radicale combined with DAVx⁵ Android app.
- Baikal combined with DAVx⁵ Android app
Those are the ones I know of that have an Android capable app. There may be others. Maybe others here will chime in with some options.
Easier to just host an .ics file with all the events in some website and let everyone use whatever calendar app they like.
Absolutely. I was just going by what the OP requested. But you’re right. There are other ways to skin the cat.
What did the cat do ? :(
LOL It’s just one of those phrases that people say. Some history tho if you like to read the etymology of words and phrases:

Thanks for the clarification!
HomeAssistant has a calendar built in
Can likely rig it up to notify of events under whatever parameters you want via push notifications
