GAS-ICS-Sync

⚠️⚠️ This project is looking for contributors and people to help answer questions! Please message @developers on the Discord! ⚠️⚠️

This is a standalone script (that consists of multiple files). The purpose is to sync ics/ical calendars to Google Calendar. Google Calendar can already do this, but updates only happen once every 12 or even 24 hrs. This script can be run much more frequently.

If you want to use this, please copy the script from here

To make a copy in the new Google Apps Script interface:

  1. Go to the project overview icon on the left (looks like this: ⓘ)
  2. Click the "copy" icon on the top right (looks like two files on top of each other)

NOTE: If too many people are accessing the file at the same time, Google may lock you out. You can follow these instructions to set up the script: https://github.com/derekantrican/GAS-ICS-Sync/wiki/Setting-up-the-script-manually
