Introduction

If you've ever wanted to manage your schedule with a calendar app, you’ve probably felt limited to the big three: Google, Apple, or Microsoft. While other options exist, most are simply frontends, meaning your actual data still ends up stored and controlled by one of these corporations.

Git Calendar changes that. Built on Git, it gives you full control over where your data lives. Host it on your own server or with any Git provider such as GitHub, GitLab, or Codeberg.

Why Git?

Because Git is cool. While its biggest feature is versioning, it also has other features/advantages that are great for using it is as a calendar backend.

• Efficient Delta Synchronization
  One of the biggest advantages of the CalDAV protocol (the industry standard for calendars) is that it only downloads changes, not the whole calendar every time. Guess what? Git does that too.
• Offline-First
  Users can edit their calendar locally without an internet connection. Changes sync automatically when the connection is restored.
• Decentralized
  Data isn't tied to a single server or cloud provider. Users can host their calendar on their own infrastructure or a public provider (e.g., GitHub, GitLab, Codeberg). Switching providers is as simple as changing the remote.
• No backend
  Git Calendar uses plain Git repositories as the storage and synchronization layer. No calendar server to run or maintain; just your client talking directly to a Git remote. One less middleman.
