It depends of the attribution days that is set up by admins.
Example with an allocation of spots is set on 2 days.
Tuesday morning, you requested a spot for the rest of the week : Tuesday to Friday.
You will know instantly if you have a spot for Tuesday and Wednesday (The days are in green when you have a spot).
The system starts the new attributions at 1pm, so I will know at 1pm if a have a spot for Thursday.
I will know Wednesday at 1pm is I have a spot for Friday.
If your planning doesn't include the week-end, and you request a spot for the next week, you will know Thursday at 1pm if you have a spot for Monday. Friday at 1pm you will know if you have a spot for Tuesday.
