trying to sort with respect to months in the date

trying to sort with respect to months in the date like I want all the data of jan,feb,march......etc together what do i use in queryfilter to filter that data,have tried playing with currMonth = today.getMonth() plus and minus

    router.get('/', isAdmin, function (req, res, next) {
    errorMsg = req.flash('error')[0];
    successMsg = req.flash('success')[0];
    var tot = totalSales(function (err, next) {
        if (err) {
            //////console.log(err.message);
            return res.error('err');
        }
    });
    var custresponse_store;
    Message.distinct('form', (err, custresponse) => {
        //res.send(messages);
        custresponse_store = custresponse;
        // console.log(custresponse);
    })
    var today = new Date();
    var currDay = today.getDate();
    var currMonth = today.getMonth() + 1;
    var currYear = today.getFullYear();
    // console.log(currYear + "-" + currMonth + "-" + currDay);
    var date = (currYear + "-" + currMonth + "-" + currDay);
    qryFilter = { "checkin": date };
    qryFilter1 = { "checkout": date };
    qryFilter2 = { "created": { $gte: moment(date) } };
    Order.find(qryFilter, function (err, docs) {
        var bookings = docs.length;
        Order.find(qryFilter1, function (err, docs1) {
            var checkouts = docs1.length;
            Order.find(qryFilter2, function (err, docs3) {
                var bookingsno = docs3.length;
                res.render('admin/dashboard', {
                    layout: 'admin-page.hbs',
                    docs: docs,
                    docs1: docs1,
                    docs3:docs3,
                    bookingsno:bookingsno,
                    noErrors: 1,
                    date: date,
                    user: req.user,
                    bookings: bookings,
                    checkouts: checkouts,
                    custresponse_store: custresponse_store
                });
            });
        });
    });
});

this is the code i currently haveand want to modify for the required result
