Display your ics calendar on your website

TL;DR: the repository of our fork of Leonaard’s original project is available here.

This started off as a simple-enough request to display a calendar in ICS format (RFC5545) on a web page.

Turns out, it’s not something so easily found. After searching for a while, it soon appeared that there was an elephant in the room that had not been addressed much to bring together the 2 big JavaScript projects around ICS and calendar display:

Eventually we spotted 2 small projects (turns out you don’t need a lot of code to get an ics URL converted and loaded into fullcalendar) doing just what we needed, and further work was done from Leonaard’s project icalendar2fullcalendar (github repository).
The edited code is terribly hack, but it does all we want so far, and it should work fine for 99% of use cases.

You can find everything on our gitlab repository which contains:

  • all code (including copy of ical.js and fullcalendar.js (in the versions that were used/modified for this particular project).
  • a README.md file containing information on where to set the ics feed(s)
  • a ‘french’ branch is also available on the repo

A working demo is running at https://nomagic.uk/js_calendar_from_ics/

note: be mindful of CORS when testing with your own feeds. Also, many feeds out there do not have the CORS rule that would allow you to load them from your own domain.

  1. Hi. I’m no dev, at least not since the days of Cobol and Fortran! Would you consider a donation or other remuneration in lieu of coding two ICS URLs, either are separate pages as you’ve described above or, for extra points, as a single calendar that display both ICS’ events in one view?

    1. Hello,
      Well I’m no developer either! We just managed to extract and use two great functionalities from two interesting FOSS programs. If you need this to work with newer versions of fullcalendar.js, this is likely to require some dev work indeed, but I’m not up to the task unfortunately (may be worth checking if it hasn’t been included to the code since then, though).
      Otherwise, as it is, you can load the ics feeds of your choice (check on the gitlab repo for a brief howto).
