Date picker week restrinctions

Need help
1

I need users to pick a delivery date, but i want to restrict the dates that they can pick to only certain weekdays.
For example, i want certain users to choose delivery dates from monday to friday; other users need to only be able to choose from dates that are either a tuesday or a friday. Any help would be appreciated, thanks.

Even the default date time picker can do that, just create data records to say the user is in a certain allowed time = either restricted submit button or push the use of the picker or even make the pick non existent based on it…

Ok, but then i would have to create a booking for every single week would’nt I?.Is there a way to block every single monday for example?

Without testing my first thought would be to have a constraint that current timeanddate:extractday is not 1.
