Every group on Radius now has a calendar feed. Members can subscribe to it in their calendar app and see upcoming events appear automatically — no copying dates, no checking the group page, no manual syncing.
How It Works #
Each group page now has a calendar subscription widget with two options:
- Subscribe .ics opens your default calendar app and sets up a live subscription. New events show up automatically; cancelled or updated events reflect the changes.
- Copy .ics Link copies the feed URL so you can paste it into any calendar app that supports .ics feeds (which is basically all of them).
Most calendar apps refresh roughly hourly (or on their own schedule), so your calendar stays current without any effort on your part.
What's in the Feed #
The calendar includes all published, listed events for the group. Each entry includes the event title, times with correct timezones, location, a summary of the description, and a link back to the full event page on Radius.
We also include events from the past three months. This prevents calendar apps from removing events you recently attended — useful if you want to look back at what you've been to.
Draft, hidden, cancelled, and unlisted events are excluded. Only events that are publicly visible on the group page make it into the feed.
Why .ics #
We went with the iCalendar standard (RFC 5545) because it's the most widely supported format for calendar data. Google Calendar, Apple Calendar, Outlook, Thunderbird, Fastmail — they all support it natively. There's no proprietary lock-in, no app to install, no account to connect. Just a URL that your calendar app knows how to read.
This matters if you care about open data and interoperability. Your events aren't trapped in Radius — they're available in a standard format that works with the tools people already use.
Works Nicely with the Events Widget #
If you're already using the embeddable events widget to display events on your website, calendar subscriptions are a natural complement. The widget shows your events to website visitors; the calendar feed puts them directly into members' personal calendars.
Between the two, your events are visible where people actually look — on your website and in their calendar — without anyone having to do anything manually after the initial setup.
Getting Started #
Visit any group page on Radius and look for the calendar subscription widget. Click "Subscribe .ics" to add it to your calendar app, or "Copy .ics Link" if you prefer to set it up manually.
If you organise a group, there's nothing you need to configure. The feed is generated automatically from your published events. Mention it to your members — it's a small thing that makes staying in the loop much easier.
