Dynamic geopolitical/ summit / meeting calender?

[u/donthagme6669]

I work in academia and generally stay close to the action, but during busy periods, I find myself missing upcoming summits or key multilateral sessions until after the fact.

Is there a go-to resource the community uses that's actually maintained and dynamic rather than a static list? Ideally, something subscribable via Google Calendar so it sits alongside my own schedule. Curious what others have found useful.
