Missing or lost events

If you think you have lost all your events because they are not visible in Google Calendar any more, please try the following:

Hidden calendars

Sign in to Google Calendar. On the left you should see a list of your personal and shared calendars under “My calendars” and “Other calendars”.

There you can decide which calendars should be visible:

Click your calendars’ names to make them visible:

Wrong account

Please check if you are using the correct account. You can see which account/email you are using at the top of the Google Calendar website. In CalenGoo you can see it under “Settings”, “Accounts” (for directly synced accounts) or you can see it in the “Settings” app of your phone (for accounts synced by Android).

Temporary unavailable

It is possible that your events are only temporary unavailable due to a problem on one of Google’s servers. This also happened in the past but is quite rare, please see here:



These calendars (or their contents) reappeared after a few days, but you must not delete and recreate these calendars in the meantime. A solution could be to use "Google Apps for Business" in the future to have phone support in such cases:


Deleted events

Perhaps your events were really deleted somehow. CalenGoo does not contain any functions to delete calendars or masses of events so it is unlikely that CalenGoo can have caused this. But if events are deleted by Google Calendar or e.g. CalenGoo, they are not really deleted, they are only marked as being deleted. To see if and when your events were deleted, please follow these instructions:

First start a program that can show you which events have been modified recently. To start the program just click this Java Webstart link:

Start LatestGoogleCalendarChanges

If you don't have Java, you have to install it from http://www.java.com first.

Enter your email and password and click "Sign in". Wait a moment, the application is a little slow and just stops working while it is downloading your calendar list. As you can see in the screenshot below, you can select a calendar on the left and see on the right which changes occurred in this calendar recently. In the example a single event was deleted. The displayed "Changed" times are GMT times! So you have to compute your local time to see which application might have deleted your events. You can use this time zone converter if you like:


If you cannot see your events there (but can sign in), either your events vanished due to a server error or the calendar was deleted and recreated.

Undeleting events in Google Calendar

If you have accidentally deleted one or more events in Google Calendar, you can undelete them using the "Trash" on the Google Calendar website:


Google Calendar does not really delete events, the events are just marked as deleted. This is necessary so that programs that sync with Google Calendar can be informed which events have been deleted.


(Mac Download, Windows/Linux Download).

As an alternative you can use the Java program here. It can also view and restore deleted events.

On Windows/Linux you need to have Java installed. If you don’t have Java, install it from http://www.java.com.

After starting it you first have to sign in and allow the program to access your calendar:

Then you should see the window below. Select a calendar, click on "Load recently deleted events", select one or more events to undelete and undelete them by clicking on "Undelete selected events". You can select multiple events by selecting the first one and clicking on the last one while holding SHIFT (to select that range of events).


After a few seconds the selected events should vanish from the list because they are no longer deleted. Now click “Refresh” in Google Calendar or reload the website in your browser to see the undeleted events:
