Class RecurrenceRule

Represents a recurrence rule for an event series.

Note that this class also behaves like the EventRecurrence that it belongs to, allowing you to chain rule creation together like so:

const recurrence = CalendarApp.newRecurrence().addDailyRule().times(3).interval(2).addWeeklyExclusion().times(2);

Modifiers like times(times) and interval(interval) are applied to the most recently added rule.
