你可以签出这段代码:

var today = new Date（）; var Christmas = new Date（today.getFullYear（） + “-12-25”）; var diffMs = （圣诞节 - 今天）;从现在到圣诞节之间的毫秒数 var diffDays = Math.floor（diffMs / 86400000）;日 var diffHrs = Math.floor（（diffMs % 86400000） / 3600000）;小时 var diffMins = Math.round（（（（diffMs x86400000） % 3600000） / 60000）;纪要 console.log（diffDays + “ days， ” + diffHrs + “ hours， ” + diffMins + “ minutes till Christmas =）”）;

或者var diffMins = Math.floor((…如果不想舍入分钟，则丢弃秒。

var startTime = new Date('2012/10/09 12:00'); 
var endTime = new Date('2013/10/09 12:00');
var difference = endTime.getTime() - startTime.getTime(); // This will give difference in milliseconds
var resultInMinutes = Math.round(difference / 60000);

一个简单的函数来执行这个计算:

function getMinutesBetweenDates(startDate, endDate) {
    var diff = endDate.getTime() - startDate.getTime();
    return (diff / 60000);
}

下面的代码对我有用，

function timeDiffCalc(dateNow,dateFuture) {
    var newYear1 = new Date(dateNow);
    var newYear2 = new Date(dateFuture);

        var dif = (newYear2 - newYear1);
        var dif = Math.round((dif/1000)/60);
        console.log(dif);

}
