You can create a one-time space booking for a single use on the Advanced Booking page. However, we recommend creating such bookings with no distraction on the Simple Booking page in Flex. Read more here: Simple booking in Flex.

When creating a single booking on the Advanced Booking page, date selection by the system has the following logic:

• If current time is before start time of working day preferences, the date is set for today. Read more about working day preferences here: Settings in Flex 
• If current time is after start time of working day preferences, the date is set for the next day.

In any case, you can change the date manually.

Now, you are all set and can view your booking under Schedule > My Bookings.
