Open Web Calendar

GitHub Workflow Status

You might want to:

There are several commercial solutions which allow embedding of calendars into my website. I only have a link to an ICS file and want to show a nice-looking calendar on my site. Browser-only calendars usually have the problem that many ICS files can not be accessed (such as ownCloud/nextCloud in my case). I also want to be in control over who knows the people who visit the site and not pass everything to Google. This is a solution in my case which I share with the world. You are free to use it or deploy your own, modify or share it. It works offline and in company networks, too.

Features

  • Embedded calendar
  • Choice of time zone
  • ICS link, best multiple
  • month/week as a view
  • name, time of event, link?
  • showing the time span
  • styling of choice (icon, color, font, ...)

Changelog

This project was funded twice - in 2024 and 2025 - through the NGI0 Core Fund, a fund established by NLnet with financial support from the European Commission's Next Generation Internet programme. You might be able to get funded, too!
