Many tools, such as booking platforms, project management apps, school and sports schedules, and public holiday calendars, only share events as an .ICS link. Subscribing to these links in a calendar app often means slow or unpredictable refreshes, read-only overlays that other people can't see, and no control over what is shown. Copying events by hand is tedious and error-prone. This connector copies ICS events into the calendars you actually use and keeps them up to date automatically, so everyone sees the right schedule in one place.

How does it work?

The iCalendar .ICS Meetings connector lets you turn any public .ICS calendar link into a live source of events for your other calendars. Paste the feed URL, and SyncPenguin regularly checks it and copies new, updated and removed events into Google Calendar, Microsoft 365, Outlook, iCloud, Exchange, Salesforce and other supported calendars. With SyncPenguin's no-code filters, field mapping and custom rules, you decide which events are synced and how they appear. You can also send one feed to many calendars, or combine several feeds into one.

Things to note

• ICS feeds are read-only by nature, so this connector works as a source for one-way syncs into your other calendars. Changes made in the destination calendar are not written back to the feed.
• The .ICS link must be reachable over the internet without a login. Most apps provide a public or secret sharing link for this purpose.
• Feeds are checked on a regular schedule rather than instantly, because ICS links do not send change notifications.
• To keep calendars clean, one-time events that started more than a month ago are not imported. Recurring events are always included.
• Only event details published in the feed are synced, such as title, time, location, description and recurrence. Attendees and reminders are not included.
• Change detection relies on the modification timestamps the feed provides, so updates may be delayed if the source app does not refresh these timestamps.

Frequently Asked Questions

What is an .ICS calendar feed?

An .ICS feed is a web link to a calendar file in the standard iCalendar format. Many apps, including booking platforms, project tools, schools and sports leagues, offer one so others can view their events.

Can I sync an ICS feed to Google Calendar or Outlook?

Yes. SyncPenguin copies events from your .ICS link into Google Calendar, Microsoft 365, Outlook, Apple iCloud, Exchange On-Premises, Salesforce and other supported calendars, and keeps them updated automatically.

How is this different from subscribing to the ICS link in my calendar app?

A subscription is usually a read-only overlay that refreshes unpredictably and is visible only to you. SyncPenguin creates real events in your calendar that can be shared, filtered and customized, and it can deliver the same feed to many calendars at once.

Is the sync two-way?

No. ICS feeds can't be edited from the outside, so the sync runs one way, from the feed into your calendars. New, updated and removed events in the feed are reflected automatically.

Are recurring events supported?

Yes. Repeating events are synced with their recurrence pattern, along with any rescheduled or cancelled occurrences.

Where can I find my ICS link?

Look for options such as "Export calendar", "Subscribe", "iCal link" or "Secret address in iCal format" in your app's calendar or sharing settings. Copy that URL and paste it into SyncPenguin.

Can I choose which events get synced?

Yes. Use SyncPenguin's no-code filters to include or exclude events based on title, location, description, dates and more. Custom rules let you change how events appear in the destination calendar.
