          default-timezone: 'Europe/Athens'
          locations: 'locations.json'

      - run: |
          git config user.name gitevents[bot]
          git config user.email ics@gitevents.org
          git add events.ics
          git commit -m "update calendar file"
          git push

This action creates / updates a file (events.ics in the example above) with the current calendar, once a day. Unfortunately, the mime-type is set to text/plain, so some calendar apps don't understand this is a calendar file.

If you're using CloudFlare, you can create a CloudFlare Worker to host this on your own domain with the appropriate headers. Just create a new service and a HTTP Route to the worker:

addEventListener("fetch", event => {
  event.respondWith(handleRequest(event.request))
})

async function handleRequest(request) {
  const ics = await fetch('https://raw.githubusercontent.com/cyprus-developer-community/events/main/events.ics')
  const res = new Response(ics.body, ics)
  res.headers.set('content-type','text/calendar')
  return res
}

Replace the URL to your events.ics file. Now you can easily subscribe to the calendar:

Local development and testing works with act.

    $ act
    $ act --list
    $ act workflow_dispatch

The github token can be stored in .secrets:

GITHUB_TOKEN=ghp_123xyz

Example locations.json file:

[
  {
    "id": "idea-cy",
    "name": "IDEA Cyprus, Nicosia",
    "city": "Nicosia",
    "geo": [35.172405, 33.36224]
  }
]
