Google Calendar Date Prefixer is an extension that enhances your Google Calendar experience by adding customizable date/time difference prefixes to event titles. This feature allows you to quickly assess the proximity of your appointments with intuitive time indicators.

Dynamic Date Prefixes automatically show how many days or hours until future events and how many days have passed since past events. Intelligent Time Display presents time in hours for events within 24 hours, in days for events beyond 24 hours, and in years and days for long-term events. Customizable Settings enable toggling the display of years for long-term events, accessible through the extension icon for seamless integration with Google Calendar.
