What is iCal Sync?
iCal sync, short for iCalendar synchronization, is a technical standard that enables the sharing of calendar data between different applications and websites. In the vacation rental industry, it is used to import and export booking information between online travel agencies (OTAs) like Airbnb, Vrbo, and a host's direct booking calendar.
This process ensures that when a property is booked on one channel, the corresponding dates are automatically blocked off on all other connected calendars.

How it works
iCal sync works by sharing a unique URL that contains a property's calendar data in the universal .ics format. A host exports this iCal URL from one platform (e.g., their Airbnb calendar) and imports it into another (e.g., their Vrbo calendar).
For a two-way sync, this process must be repeated in the opposite direction. The receiving platform then periodically fetches updates from the source URL to refresh its availability.
It's important to note this synchronization is not instantaneous; there is often a delay that can range from minutes to several hours, depending on the platform.
Why it matters
iCal sync is crucial for hosts who list their property on more than one channel without using a centralized property management system. Its primary function is to prevent double bookings, which can damage a host's reputation, lead to negative reviews, and result in penalties from OTAs.
This simple form of calendar synchronization allows hosts to maximize their property's visibility across multiple distribution channels while maintaining a single, consolidated view of their availability.
Examples
- A host lists their beach house on both Vrbo and their own direct booking website. They import the Vrbo iCal link into their website's calendar and vice versa, ensuring that a booking on either platform blocks the dates on the other.
- A property manager uses iCal sync to connect their Booking.com calendar to a new, niche listing site that does not offer a direct API connection. This allows them to test the new channel without manually blocking dates.
- A host who rents out a room in their house on Airbnb wants to use a personal Google Calendar to track all their commitments. They use iCal sync to import their Airbnb booking calendar into their Google Calendar for a unified view of their schedule.
