$('#calendar').fullCalendar({
 	viewRender: function(currentView){
		var minDate = moment(),
		maxDate = moment().add(2,'weeks');
		// Past
		if (minDate >= currentView.start && minDate <= currentView.end) {
			$(".fc-prev-button").prop('disabled', true); 
			$(".fc-prev-button").addClass('fc-state-disabled'); 
		}
		else {
			$(".fc-prev-button").removeClass('fc-state-disabled'); 
			$(".fc-prev-button").prop('disabled', false); 
		}
		// Future
		if (maxDate >= currentView.start && maxDate <= currentView.end) {
			$(".fc-next-button").prop('disabled', true); 
			$(".fc-next-button").addClass('fc-state-disabled'); 
		} else {
			$(".fc-next-button").removeClass('fc-state-disabled'); 
			$(".fc-next-button").prop('disabled', false); 
		}
	}
});

how can i disable previous button that user not to enter past date?
i'd used this condition,but its not working
if($("#startdatepicker1").datepicker("getDate").getDate() < today)

Thank you, I was in great need of this solution.

Clean and simple solution that worked perfectly from the go. Thanks!

Thanks!

If they need to disappear with the buttons just assign to the Header as follows.

header: {
   left: '',
   center: 'title',
   right: ''
 },

Thanks a lot!
