  • This plugin kicks ass

    Finally! Exactly what I need and nothing more. I went through way too many, way too go-pro-spammy, admin-view-ruining calendar plugins before finding this gem. One feature request: a boolean param for including/excluding eventless days in list view. In my case, including them would make sense.

  • Failed for me ¯\_(ツ)_/¯

    This is the only free plugin I could find that pulls a public calendar into a web page. I am using Elementor, so I had to use shortcode. I couldn't get it to show just the list view. Both views look ugly in the side column where I put it. I did not want to spend the time to inspect each element and write custom CSS.

  • Simple to use and just works

    Thank you for this plugin, I was just using a Google Calendar embed which didn't look great and searching for an alternative came across this. It's slotted in perfectly to the website, is easy to use and after a bit of reading the documentation and the FullCalendar docs I can customise it pretty easily. It's a great plugin.

  • Easy and lightweight

    Fantastic plugin, thanks for sharing it to generously!

  • Easy, lightweight, all the settings you need

    Painless migration from the old Pretty Google Calendar. Easy to implement, mobile responsive, just enough view options without including too many, and easy CSS class implementation for extra styling. Never had any issues with PGC and don't expect any from Hydrogen either; it's set and forget. Perfect solution for something like club or charity event calendars.
