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?


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.
