Google Calendar Event Deduplicator

This repository contains some scripts that helped me deduplicate thousands of events that got created when I imported my calendar to Fastmail.

⚠️ Unmaintained ⚠️

Requirements

The scripts have the same requirements as described in the Google Calendar Quickstart example

1. Python 2.6 or greater
2. The pip package management tool
3. A Google Cloud Platform project with the API enabled
4. Authorization credentials for a desktop application
5. A Google account with Google Calendar enabled

Usage

1. Install the necessary libraries by running pip install -r requirements.txt in src
2. Generate an OAuth Client ID for a Desktop Application and save the file as credentials.json in the same path as the scripts
3. Run any of the scripts in src

Caveats

Since this is a quick and dirty hack for myself there are some caveats:

• Duplicate events are simply matched by a prefix that Fastmail added to their events, replace it with the prefix that was added to your events
• There is a very annoying and possibly undocumented rate limit on the number of requests you can fire in a - unknown to me - timespan, maybe due to the app being in Test-mode when I generated the OAuth credentials

Disclaimer

I have no intention to maintain or troubleshoot this code: I published it because it helped me fix my problem and it might help someone else.
