Google Script: How to get Recurring Events from Google Calendar?

Question

There's a popular script on various websites that allows one to easily export Google Calendar events to a Google Spreadsheet. It works fine ... except that it does not work with recurring events.

Here's the crux of the code:

var mycal = "sample@gmail.com";
var cal = CalendarApp.getCalendarById(mycal);
var events = cal.getEvents(new Date(startDate), new Date(endDate));

Then one just needs to iterate through the members of 'events'. The problem appears to be that recurring events are defined in another way which 'getEvents' does not understand. Thus a query of a date range containing only recurring events finds nothing.

I'm wondering if anyone has written some code that would properly query for recurring events?

Answer 1

Your assumption is not correct, recurring events are returned exactly as any other ones.

I don't know what script you use but if you can't get the recurring events then I guess this script is just not good.

I'm not going to publish the whole code here because the version I use is a bit long but you can make a copy of this spreadsheet and test it yourself.

Run opOpen once from the menu to get the authorization then use the spreadsheet menu. You'll get a UI that will ask you to define which calendar to use and the start / end dates. These values will be stored in properties for next usage.

Answer 2

Serge, you're correct, it does handle recurring deliveries. My failure was to include the start time and end time in addition to the date. Once I did that, via a simple string concatenation, then all worked properly.

Thank you for your feedback!
