Event Merge for Google Calendar™ is a handy Chrome extension designed to simplify your Google Calendar experience. When you have the same event appearing on multiple calendars—like work, personal, or team calendars—this tool visually merges those duplicates into a single event. Each merged event displays color-coded strips representing the individual calendars it belongs to, helping reduce clutter and improve calendar readability.

Ideal for busy professionals juggling multiple schedules, this extension streamlines calendar management and ensures you don't miss important events. The project is open source, with its code available on GitHub, and user feedback and bug reports are welcomed through its GitHub issues page.

User reviews

Event Merge for Google Calendar™ is highly praised for its ability to clean up duplicate events across multiple calendars, drastically improving organization and usability, especially in shared or work contexts. Users find it reliable, easy to use, and indispensable. However, recent Google Calendar updates have caused functionality issues starting in 2024, with some event types and views not handled properly. The extension also lacks mobile support and could benefit from more customization features. Despite these downsides, it remains valued and viewed as a game-changing tool that many wish Google would integrate natively.

Pros

Effectively merges duplicate events from multiple calendars, cleaning up and simplifying calendar views.
Highly reliable and easy to use with immediate positive impact on calendar organization.
Significantly improves the user experience when managing multiple Google Calendars, especially in workplaces and shared environments.
Loved by users who have relied on it for years, indicating consistent performance and trustworthiness.
Free and well-maintained extension appreciated by the community.

Cons

Stopped functioning properly in 2024 due to Google updates, causing disappointment among users.
Lacks features to handle new Google Calendar event types like appointment schedule and location events correctly.
Not fully compatible with all calendar views, particularly default month view, without extra user action.
Does not have an official mobile solution or equivalent for Android and iPhone users.
Limited customization options, such as merging 'busy' events and visual improvements for event readability.

This is amazing for cleaning up my work calendar when many of us are attending the same meetings/ events. Google, please stop making it unavailable. Or add your own feature to Google Calendar that does this. It is a game changer!

There is no other extension that cleans up our organization calendar by merging events. Managing our calendar just became more difficult and there are no alternatives available with this function. Please reconsider removing this extension or else consider offering an alternative!
