The calendar between two moments, as the Calendar page of the app shows it: every occurrence in the window, a repeating event once for each time it happens, sorted by start, with its event id, place, status and your answer. from and to are ISO 8601 with a zone, at most a year apart, and timezone (an IANA zone, UTC unless you say) decides what an all-day event means. When more follow, the last line gives the offset to pass back.

One calendar event in full: when it is, where, who organised it, every attendee and their answer, your own answer, how it repeats and its reminders. Pass id for an event from listCalendarEvents, or threadId for the invitation a conversation carries.

Put an event on the calendar, as New event on the Calendar page does. start and end are ISO 8601 with a zone. With attendees, an invitation goes to each of them from the address in from, which has to be one you may send as, unless sendInvites is false. reminders takes minutes before the start, and recurrence an RRULE such as FREQ=WEEKLY;BYDAY=MO.

Change an event you organise: its title, time, place, attendees, reminders or repeating. A field left out keeps its value, and attendees replaces the whole list. Everyone invited gets the updated invitation unless sendInvites is false.

Call off a meeting you organise, as Cancel meeting does in the app: it stays on the calendar marked cancelled, and everyone invited is told it is off, from the address in from. A chat always asks first.

Remove an event from the calendar for good, as Remove does in the app. Nobody else is told, so call off a meeting with others in it with cancelCalendarEvent instead. A chat always asks first.

Answer an invitation: ACCEPTED, DECLINED or TENTATIVE. The answer goes to the organiser by email from the invited address you may send as, or from respondingAs when the invitation went to more than one of yours.
