Delete Google Calendar duplicates from any browser

This is the EASIEST and FASTEST way to remove event duplicates, undo iCal import (iCal or CSV) and undo failed syncs on Mac, Linux or Windows without installing any software. If you only need basic Google Calendar maintenance then instead of installing the Desktop GCalToolkit software you may prefer to use the online version of GCalToolkit at The online tool loads all events from your agenda directly into your browser, removing duplicates and syncing or import errors with just a few clicks. Most importantly, the Online Version is very fast and requires NO INSTALLATION:

GCalToolkit with no installation necessary


If you use Outlook®, iCal, Sunbird or any smartphone (Android, iPhone, Blackberry...) that can sync to Google, then you can set up 2-way sync between your calendar and Google Calendars to take advantage of the power of GCalToolkit - this means that you can delete duplicates, mass edit, mass delete, search/replace, shift events, spreadsheet export etc. in ANY CALENDAR SOFTWARE using GCalToolkit. Please visit either the pages ONLINE GCT or DESKTOP GCT for more information on the full editing power of GCalToolkit.

The FULL VERSIONS are valid for one household (or a few business users) on unlimited Google Calendars. The Full Version allows you to process ALL EVENTS on ALL your Google Calendar agendas. Please keep your account details private; Google places a limit on the number of daily requests software such as this can perform, so it's just not fair to everyone else if you hand out your details to all your colleagues and friends. Not to mention that the GCalToolkit server will detect multiple installations. Accounts may be suspended if misused, so please, one household... one or two business users.

Please Note: If ever support requests exceed a certain limit we will have to remove the "Lifetime" deal, so get it now while stocks last!

The FREE VERSION allows you to process events that start 3 months in the past and 3 months in the future (or 500 events with Online Tool)

(* i.e the lifetime of GCalToolkit)
