> There's an open standard, icalendar (https://icalendar.org/) which represents calendar entries. Invitations you get in the mail come this format too. The easiest way for your map, address book, reminders etc to integrate is just to talk to your calendar server. The apps need not know about each other at all.

> Google and microsoft of course may do some non-standard futzing around within their proprietary stacks: you can often see these problems when you try to connect to something outside their silos, though in my experience the standards integration in google calendaring is pretty good (especially when compared to their mail system).

Yes, crossing the two is often still a hot mess.

The first paragraph sounds great in theory. The second paragraph sounds more like what happens in practice...

Well, the real problem is letting big companies get away with shitty implementations.

In any case... here we are, in a world where 95%+ of the people I share / use calendars with are via orgs owned by one of two big tech companies.
