var startDate = new Date(2012, 03, 10, 12, 0, 0);
var endDate = new Date(2012, 03, 19, 14, 0, 0);
 
        var out = [];
        var calendars = Ti.Calendar.allCalendars;
        Ti.API.info('-> '+JSON.stringify(calendars));
        for (var i=0; i < calendars.length; i++) {
            Ti.API.info('=> '+JSON.stringify(calendars[i]));
                var cal_events = calendars[i].getEventsBetweenDates(startDate,endDate);
 
                for (var j=0; j < cal_events.length; j++) {
                    out.push(cal_events[j]);
                };
        };
