Enabling Calendar (and Event)

The Calendar plugin can be enabled either by the toggle or from its settings, both accessible from your admin/plugins page:


Somewhat unsurprisingly, Discourse Calendar (and Event) adds both the calendar and event features to your Discourse site. With these, you can create individual topic calendars to track important occasions or timelines, display calendars in categories, add a holiday calendar to mark vacations, absences, or sick days, create interactive event topics, as well as show an easy-access calendar summary of all of your upcoming events.


Bespoke calendars can be created in multiple topics, and ones you wish to give higher visibility to can be displayed above a category’s topic list.

You can find more detailed information on how to create and use calendars in:


The Event feature allows interactive elements to be inserted into topics which your members can use to sign up to attend or participate in your community’s activities. These are all summarised in a dedicated site-wide calendar, with the option to add an easy-access link to your navigation menu. You can find more information on how to create and use this feature in:

This plugin is promising - but there’s some features that are missing that prevents us from jumping from Pavilion’s plugin

  • Display non-all-day events with the start time on the calendar, currently every event looks like an all day event.

  • ‘Add Event’ button in the composer next to the tag selector (not hidden in the cog)

  • Limit which categories can have events, and if a events are compulsory in a category

Nice to haves:

  • Event meta data in the topic only appears/is entered at the top of the topic (instead of where ever the curser is
  • ability to limit which groups can make events in a category (for example - only ‘EventPlanners’ group can create events in the ‘Discussion’ category, but all users can create non-event topics (or edit topics if the topic is set to Wiki)
  • change URL of /upcoming-events to /calendar

2 posts were split to a new topic: Holiday status being incorrectly applied

Hello there,
Thank you for this work.

I have 2 UX questions:

  • Is it possible to display “Add event” button next to “Add location” button in topic editor ? Like it was the case with pavillion plugin ?

  • Is there a possibility to add Calendar top menu entry ? I don’t find it in settings

This looks great! Some thoughts/questions:

Am I correct in assuming that to create a calendar you simply create a new thread/topic, and paste the following into it:

Name Of Calendar 


Then to add entries to the calendar you simply make a new post in the sam thread with something like the following (by clicking on the insert time/date icon in the post options):

Name of Event/Entry

[date-range from=2024-04-18 to=2024-04-19 timezone="Europe/London"]

This adds the entry to the calendar which is great, however:

  • Is there any way to add entries to a calendar but let those entires have a dedicated thread/topic as well? (I see you can add events in new threads, but there doesn’t appear to be any way to add those events to a calendar).
  • Is there any way to feature ‘Upcoming Events’ from a specific calendar in the digest emails? Or maybe the left hand column, and with each entry linking to the dedicated thread for that entry?

If this is not currently possible do you have any plans to add it?

@vinothkannans Could you help me review this pr?

Are there plans to add a URL feed that users can subscribe to? I’m sure it would be tricky for all events vs the ones they have RSVP’d to.

Secondly, an additional layer would be amazing if it could recognize private events (or maybe that’s just a different URL feed per group).


There is no rss feed for the /upcoming-events url though—that would be a nice addition!

What about caldav sync ?


That would also for me be a reason to switch, indeed.

This needs more updating as it mentions a. Event Insert in composer and adding event details not as pictured. Unless Event was an add on?

I’ve installed the plug-in and the calendar tag works in the first post of a topic. But I don’t see any event or calendar options in the gear menu:

Can someone please explain what I need to do to get the event option in the gear menu?

You need to enable the Event portion of the plugin discourse post event enabled


Thanks. I somehow missed this setting.


How do you get create event to show in a Category topic with replies being events?

I see the create event works on creating new topics. But looking to have a Calender in a topic with replies adding events. It works partially with insert date but not as good as create event has more options.

Currently users can set the region in their profile preferences.

I’d like to let them set their region during signup by showing this field in the registration form. Is that feasible?
