As of today, you are not able to change the rental date yourself. To change the date, you must therefore either cancel the booking and then the customer can send a new, updated rental request or contact our support and we can manually change it for you.
If you decide to postpone the rental period for a paid booking to a later time without changing the booked date in the system, the system will automatically mark the rent as completed when the booked date has passed. It is therefore good if the correct date is set in the system to prevent this from happening. Changing dates can only be done before the rent is completed.
