Full Calendar get date from selected Week

I'm using FullCalendar plugin(week view) for jQuery in my project. In fullCalendar week view, I can see a row showing the date in following format:- Sunday 9/6, Monday 9/7, Tuesday 9/8 so on...

var calendar = $('#calendar').fullCalendar(
                {
                    header: {
                        left: 'prev',
                        center: 'title',
                        right: 'next'
                    },
                    defaultView: 'basicWeek'                    
                });
            });

Now i have used only header format in calendar for timesheet project. I want to get dates 9/6,9/7 from current selected week in alert when move to next/previous week(This is for store date in database). It is possible to get dates seperately for current week

Thanks
