Amend some Javascript validation code for a date picker so tomorrows date is excluded

I have a web form on a Joomla website using BreezingForms. It includes a date picker so visitors can choose a booking date.

I currently have some validation code on the form submission routine that alerts if the date is in the past, is a Sunday or is todays date, but I also need it to alert if the visitor selects tomorrows date.

Hopefully this is a quick and easy bit of coding for someone who knows Javascript, current code is below. I don't mind if this is adjusted or its completely re-written, whatever is easier so long as it alerts for past dates, today or tomorrow and Sundays.

function ff_date_validation(element, message)
{
var data = element.value ;
data = data.replace("/","-");

var dmy = data.split("-");

if (dmy.length != 3)
{
return ( message == '' ) ? message : " Please tell us which day you'd like the service to take place " ;
}

var vDate = new Date(dmy[2] - 0, dmy[1] -1, dmy[0] - 0,0,0,0,0);

//alert(vDate);

var today = new Date();

//alert(today);

if(vDate.getTime() 1)
{
return "Unfortunately we cannot take bookings for today or tomorrow.";
}
}
else
{
return "The date cannot be in the past.";
}
}
if ((vDate.getDay() == 0) || (vDate.getDay() == 7))
{
return "Unfortunately we cannot take bookings on Sundays";
}
return '';
} // ff_date_validation
