var data = {};
data.weeks = {};
data.currentCalendarMonth = moment().startOf('month');

buildMonth();

function buildMonth() {

    data.weeks = {};
    var startOfMonthISOWeek = data.currentCalendarMonth.clone().startOf('month').isoWeek();
    var endOfMonthISOWeek = data.currentCalendarMonth.clone().endOf('month').isoWeek();

    for (var i = startOfMonthISOWeek; i < endOfMonthISOWeek + 1; i++) {
        data.weeks[i] = [];
        buildWeek(i);
    }
}

function buildWeek(isoWeekNumber) {

    var start = moment().year(data.currentCalendarMonth.get('year')).week(isoWeekNumber).startOf('isoweek');
    var firstDayOfTheWeek = start.clone();

    for (var i = 0; i < 7; i++) {

        var day = firstDayOfTheWeek.clone().startOf('day').add(i, 'days');

        data.weeks[isoWeekNumber].push({
            date: day.get('date'),
            month: day.get('month'),
            year: day.get('year'),
            day: day
        });
    }
