        var today = new Date();
        var dd = today.getDate();
        var mm = today.getMonth() + 1; //January is not 0!
        var yyyy = today.getFullYear();
        if (dd < 10) { dd = '0' + dd }
        if (mm < 10) { mm = '0' + mm }
        today = yyyy + '-' + mm + '-' + dd;
        return today;
    };
    function getYearAgo(){
    var lastYear = new Date();
    var dd = lastYear.getDate();
    var mm = lastYear.getMonth() + 1; //January is not 0!
    var yyyy = lastYear.getFullYear(getTodayDate) - 1;
    if (dd < 10) { dd = '0' + dd }
    if (mm < 10) { mm = '0' + mm }
    lastYear = yyyy + '-' + mm + '-' + dd;     
    return lastYear;
