you have just introduce parameter startDate as mentioned below.

var todaydate = new Date();
    $(".leave-day").datepicker({
        autoclose: true,
        todayBtn: "linked",
        todayHighlight: true,
        startDate: todaydate     
      }
    ).on('changeDate', function (e) {
        var dateCalendar = e.format();
        dateCalendar = moment(dateCalendar, 'MM/DD/YYYY').format('YYYY-MM-DD');
        $("#date-leave").val(dateCalendar);
    });
