Double-booking risk
If a platform retrieves an event too late or incorrectly, the same dates may still appear bookable elsewhere.
iCal synchronisation for holiday rentals
Stop calendar chaos between your booking platforms.
kalenderabgleich.de is for hosts who do not need a full channel manager, but want to connect their iCal calendars reliably in one central place. Each platform connects only to kalenderabgleich.de – no longer directly to every other platform.
Try free for 30 days. Then €8.99 incl. VAT per property per month, cancellable monthly.
No large management software. No channel-manager overkill. Just the calendar synchronisation small hosts actually need.

Direct booking
Source retrieval every 10 minutes
No return to source portal
The problem
Directly linked platform calendars quickly create incorrect blocks.
Zombie bookings
Old imported blocks can remain even though the booking was changed or deleted.
Calendar chains
Platform A imports platform B, platform B imports platform C, platform C imports platform A again – in the end it is no longer clear where a block came from.
The solution
One central iCal hub instead of many direct platform links.
Each platform sends its iCal calendar to kalenderabgleich.de. kalenderabgleich.de then creates a dedicated export calendar for each platform.
The key difference: an event is not sent back to the platform it originally came from. This avoids self-blocking and unnecessary feedback loops.
