How to delete/update only one event from a recurring one?

[Radek Šimčík]

Hi all

I want to know how to edit/update recurring event. How to "simulate" dialog box from Calendar GUI

"Delete recurring event"

- this event

- this and following events

- all events

I created StackOverflow question for that one https://stackoverflow.com/q/72043967/250422

Thank you

This took a while to figure out, but I got some of it working. Basically, there is no modifying of existing eventRecurrences and

instead of modifying it, you replace it by creating a new one with the options you want. This example is probably the hardest,

removing a single occurrence from the series. From here, the rest is easy. 

function removeSingleEvent() {

  var recurringEventName = "Monday Meeting";

  var startDateTime = new Date('May 2, 2022 13:30:00 EDT');

  var startDate = new Date('May 2, 2022');

  var endDateTime = new Date('May 2, 2022 14:30:00 EDT');

  var dateOfExclusion = new Date('May 23, 2022');

  var events = CalendarApp.getEventsForDay(startDate, {title: recurringEventName}); 

  var eventSeries = CalendarApp.getEventSeriesById(events[0].getId());

  var recurrence = CalendarApp.newRecurrence()

    .addWeeklyRule().times(52)

    .addDateExclusion(dateOfExclusion);

  eventSeries.setRecurrence(recurrence, startDateTime, endDateTime);

}
