Validate date

[Mathiassen1990DK]

Hello

is it possible to check if a value entered in the input field is a valid date for the datepicker?
My issue is that i disable a lot of dates for order delivery purpose. So i need a way to validate the date entered in the datepicker input field, and check that the entered date is not disabled.

Is there any way i can do this?
