ICalSync
Seamlessly Sync Calendars, No More Meeting Mix-ups!
Sync multiple external calendars into Google Calendar in realtime, from any iCal (.ics) feed.
Many calendars, one view
Point ICalSync at any external iCal feed — a client's calendar, a booking system, a university timetable — and it lands in Google Calendar alongside everything else.
Realtime, not nightly
Changes on the source calendar follow through as they happen, so the version you are looking at is the version everyone else is looking at.
No more mix-ups
Double bookings and missed events come from calendars that never talk to each other. This one makes them talk.
Up and running in minutes
Install from the Marketplace
Open the listing, choose Install and grant the calendar permissions the app explains up front.
Add your calendar feeds
Paste the iCal URL of any external calendar — a client's, a booking system's, a timetable.
Pick the destination
Choose which Google Calendar the events should land in, and how they should be labelled.
Leave it running
From then on the sync follows changes on the source calendar in realtime. Nothing else to do.
Before you install
Which calendars can I connect?
Anything that publishes a standard iCal (.ics) feed — most booking systems, university timetables, project tools and other calendar providers do.
How quickly do changes appear?
Updates on the source calendar follow through in realtime rather than on a nightly batch.
Can my whole organisation use it?
Yes. A Google Workspace administrator can install ICalSync domain-wide from the Marketplace.
What happens if I uninstall?
Access is revoked immediately from the Marketplace or your Google account's connected apps.
Add ICalSync to your workspace
Free to install from the Google Workspace Marketplace.
