If you accidentally deleted a calendar entry, Google’s latest update for its Calendar is your new friend. It adds a trash feature where you can restore your deleted entries. It’s available for both individual and recurring events you have deleted in your calendar or other calendars you have editing rights to.
To access your junked events, simply click on the drop-down arrow next your calendar. Just like in Gmail you can also permanently delete items from your trash bin, too. This feature is coming to Google Calendar on the web in the coming days.
