Google Calendar is a great cloud computing calendar solution which allows you to manage your calendar online, as well as invite others to shared events.

One feature Google Calendar is missing though is the ability to delete more than one event at a time. However, by using the remote calendar functionality Google Calendar offers, you can get around this.

(This solution uses iCal on OSX but you could use a similar approach with GooSync for Outlook if you’re on Windows.)

1. In iCal, select Preferences from the iCal menu.
2. Go to the Accounts tab and add a new account (+)
   
3. Select CalDAV from the Account Type then enter your Google username and password.
4. Enter the Server Address as google.com.
5. On the Server Settings, make sure the Server Path is set to /calendar/dav/[username]/user where [username] is your Google username.
6. You have now configured your Google Calendar to sync up with iCal.
7. If you have a mass of events with similar content that you need to remove, search for that term eg. “Morning Meeting”.
8. Select all the events and delete.
9. When iCal synchronizes with Google Calendar, all those events will be removed.
