We close reservations for tomorrow at exactly 17:00. How can we configure it?

You can achieve this setup by using dynamic time boundaries. At 17:00, the start time should be shifted to the day after tomorrow. Let's calculate how many hours you need to shift the start time:

(24 - 17) + 24 = 7 + 24 = 31.

Now, let's configure this for hourly rentals.

Open the rule settings. Set the Shift start from the current moment parameter to 31 h. Then, set it to round up to the beginning of the day. Save your changes.

Now, at 16:00, the time will first shift to 23:00 tomorrow and then round up to the beginning of tomorrow.

And at 18:00, the time will first shift to 1:00 the day after tomorrow and then round up to the beginning of the day after tomorrow.
