Get date from fullCalendar and set new Date() hours, minutes, seconds and milliseconds to 0 and create next day date and then compare date.

Check below snippet:

var selectedDate = "2015-10-20";  // Replace with $('#selectedDate').val();
var today = new Date();
var selectedDate = new Date(Date.parse(selectedDate));
today.setHours(0);
today.setMinutes(0);
today.setSeconds(0);
today.setMilliseconds(0);
var nextDay = new Date(today.getTime());
nextDay.setDate(nextDay.getDate() + 1);
if(selectedDate < today) {
  snippet.log('Date is before');
} else if(selectedDate >= today && selectedDate < nextDay) {
  snippet.log('Date is today');
} else {
  snippet.log('Date is after');
}

    var selectedDate = $('#selectedDate').fullCalendar('getDate').format();
    var currentDate = new Date();

    if(new Date(selectedDate)  <= currentDate ){
            alert('before date')
        }
