+- There are bi-weekly calls immediately following the
+  [Serverless/CloudEvents call](https://github.com/cloudevents/spec#meeting-time)
+  at 9am PT (US Pacific). Which means they will typically start at 10am PT, but
+  if the other call ends early then the SDK call will start early as well. See
+  the
+  [CloudEvents meeting minutes](https://docs.google.com/document/d/1OVF68rpuPK5shIHILK9JOqlZBbfe91RNzQ7u_P7YCDE/edit#)
+  to determine which week will have the call.
