Custom Calendar Background is a Chrome extension that transforms your Google Calendar’s appearance by adding full-page background images or colors. Whether you prefer to use your own photos or select from a curated collection of themed backgrounds, this extension helps personalize your calendar interface.

Please note that due to recent updates adding dark mode to Google Calendar, the extension currently works best with light mode enabled, alongside an optional dark overlay setting to balance visibility. For issues and support, the project maintains an open GitHub repository.

User reviews

Users appreciate Custom Calendar Background for enhancing Google Calendar's appearance with vibrant, personalized backgrounds and responsive developers. However, multiple reviews report recent issues where the calendar's main area shows a white background instead of the selected image, especially in week and month views. Users also find changing backgrounds confusing due to URL requirements and have experienced text visibility problems. Despite some bugs and usability concerns, many long-term users remain loyal to the extension for improving their calendar experience.

Changing the background is confusing; requires users to input image URLs which often don't work.

Lack of variety and some find it not user-friendly or archaic.
Occasional bugs causing calendar background to lag or display incorrectly.

Funcionaba bien hasta hace poco. Aunque las URL se encuentran correctas no está cargando la imagen. Pausaré su uso y volveré más tarde a ver si lo corrigieron. --- ¡Hola, Patrick! No vi opción de "responder", así que respondo editando mi comentario: Es la misma versión de Windows, la URL está correcta. Estoy viendo que a otros usuarios les ocurrió lo mismo.

I love the idea, but whenever I downloaded this and was using it, my description of timeblocks, the text of it was unreadable with this extension, it was all dark.
