Tags for Google Calendar™ is a Chrome add-on developed by soimon. This free program enhances the functionality of Google Calendar by adding special markup to tags and question marks in event names. With this add-on, users can easily discern different kinds of events without the need for creating multiple calendars.

One of the key features of Tags for Google Calendar™ is the ability to display colored tags for events that contain a colon (:) in their names. The part before the colon is displayed as a colored tag, helping users quickly identify different types of events. For example, an event named "Tag: Event name" would be displayed as "[Tag] Event name". This feature eliminates the need for creating numerous calendars for different event categories.

Additionally, this add-on also allows users to mark events ending with a question mark as optional or yet to be confirmed. These events are displayed in italic and transparent, making it easy to differentiate them from confirmed events.

Tags for Google Calendar™ is a useful tool for enhancing event organization and visual clarity within Google Calendar. It is an intuitive and accessible add-on that improves the user experience without any additional cost.
