Will it be in my calendar?

Yes. The confirmation email carries a standard calendar invitation with the join link on the entry, and there is an “Add to calendar” button on the confirmation screen. If the time later moves, the same entry moves with it.

Your calendar

The confirmation email carries a calendar invitation, so the call lands in Outlook, Google Calendar, Apple Calendar or anything else that reads a standard invite — with the join link on the entry itself. There is an “Add to calendar” button on the confirmation screen too, for when you book on one machine and keep your calendar on another. Anything that happens afterwards — a move, a cancellation — updates that same entry rather than adding a second one.
