ICS to GCal is a Chrome add-on developed by Fabian Henneke that allows users to easily import .ics files into their Google Calendar. With just two clicks, users can import events from .ics files without the need to open the Google Calendar settings.

One of the key features of ICS to GCal is its ability to correctly import recurrent events, to the extent that they are supported by Google Calendar. The add-on also automatically fixes common deviations from the iCalendar specification, such as trailing commas in date lists and exceptional dates not specified with the correct time.

To use ICS to GCal, users simply need to right-click on a link to an .ics file and select a calendar to add the events to. A popup notification will then inform the user about the number of events added and provide options to view the event or undo the changes.

ICS to GCal is a free add-on and can be found on the Chrome Web Store. It is a convenient tool for users who frequently come across interesting events online in the form of .ics files and want to easily import them into their Google Calendar.
