Is your feature request related to a problem? Please describe.

When a specific day does not have time slots, e.g. Saturday and Sunday in this case:

... the day is still clickable in the date picker:

... but no time slots can be chosen:

Describe the solution you'd like

I believe that from a UX standpoint, it would be better to simply grey out the dates in the date picker, as is done with past dates:

With the current behaviour, the user will have to mentally process why no time slots are available for the chosen date. Which is not the case when the date cannot be picked at all.
