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.

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