About Google Calendar Themes & Dark Mode
📅 Give Google Calendar a Cleaner, More Personal Workspace
Google Calendar Themes & Dark Mode lets you completely transform the appearance of calendar.google.com without altering any of your actual events or calendar data. Choose a ready-made polished theme for a consistent interface, or use Background mode to set the perfect mood with custom images and transparency controls.
✨ PREMIUM FEATURES

Change up your workspace instantly with our carefully designed palettes: Graphite (dark mode enabled by default), Midnight, Forest, Dusk, and Paper.
🖼️ Custom Backgrounds
Make your calendar truly yours. Choose from three stunning built-in background styles, or upload your own personal PNG, JPEG, or WebP images.
🎛️ Advanced Visual Controls
Fine-tune your perfect setup. Adjust background blur and dim settings, and choose between Fill or Fit controls for your images.
🔍 Calendar Transparency
Never sacrifice readability. Use our transparency control to perfectly balance your calendar events against your beautiful custom backgrounds.
