An iCal synchronisation keeps your holiday home calendar up to date across different booking platforms. When a booking is made on one channel, the same dates are blocked on your other channels, which helps you avoid double bookings.

What is iCal?

iCal, short for iCalendar, is a common calendar format. Many booking platforms and calendar apps, such as Airbnb, VRBO and Google Calendar, use it to share availability. The shared link is usually a file that ends in .ics.

How does iCal synchronisation work?

Each platform shares its calendar as an iCal link. Holidu reads that link and updates your availability to match. This means your calendars stay aligned without you needing to enter every booking by hand.

Why should hosts use iCal synchronisation?

• Saves time: You do not need to update each calendar manually.
• Keeps availability consistent: Guests see the same free dates on every listing site.
• Reduces double bookings: Blocked dates help prevent overlapping reservations.

Good to know

Synchronisation is not always instant. Changes can take a few hours to appear on all channels, so keep this in mind when you receive last-minute bookings.
