When working on some Practice Cases in the Software Factory, we have been looking for a way to lock/block dates for user’s to select upon populating a ‘Date’-input field in the app.

Example situations would be: 

• In an app that lets users reserve a slot for car maintenance, haircut or any other type of appointment, a selected date could ofcourse never be in the past. 
• If a librarian is manually entering the return date of a book, this date could never be before the issue date the book. These dates should ideally be automatically blocked from selecting. 

So far we have not found any proper workarounds other than having a error message pop up once the user is selecting an invalid date. This for sure is not the ideal user experience.

Any possibility to have this functionality integrated? Or are there any alternative solutions we may have overlooked?
