Google Script Calendar

Google Script to change privacy of events in Calendar

For unkown reason (probably me), several events in my Calendar  went "public"...

This is how I made them private (my "default" is "private" ):

1. Go to https://script.google.com/home
2. Create new Project
3. Use this code (has many drawbacks)
   

function main() {
  var now = new Date();
  var oneYearBefore= new Date(now.getTime() - (365 * 24 * 60 * 60 * 1000));
  var events = CalendarApp.getDefaultCalendar().getEvents(oneYearBefore, now);
  events.forEach(function(e) {
   e.setVisibility(CalendarApp.Visibility.DEFAULT);
 });
}
