在 Moment Js 中获取两个日期之间的小时差

Question

我可以使用 MomentJs 获得两个日期之间的差异，如下所示：

moment(end.diff(startTime)).format("m[m] s[s]")

但是，我还想在适用时显示小时（仅当 >= 60 分钟过去时）。

但是，当我尝试使用以下方法检索持续时间时：

var duration = moment.duration(end.diff(startTime));
var hours = duration.hours();

它返回的是当前小时，而不是两个日期之间的小时数。

如何获得两个 Moments 之间的小时数差异？

Answer 1

你很接近。 您只需要使用duration.asHours()方法（请参阅文档）。

var duration = moment.duration(end.diff(startTime));
var hours = duration.asHours();

Answer 2

以下代码块显示了如何使用 MomentJS 计算两个日期之间的天数差。

var now = moment(new Date()); //todays date
var end = moment("2015-12-1"); // another date
var duration = moment.duration(now.diff(end));
var days = duration.asDays();
console.log(days)

Answer 3

或者你可以简单地做：

var a = moment('2016-06-06T21:03:55');//now
var b = moment('2016-05-06T20:03:55');

console.log(a.diff(b, 'minutes')) // 44700
console.log(a.diff(b, 'hours')) // 745
console.log(a.diff(b, 'days')) // 31
console.log(a.diff(b, 'weeks')) // 4

Answer 4

有一个叫做fromNow()的伟大moment方法，它将以人类可读的形式返回特定时间的时间，如下所示：

moment('2019-04-30T07:30:53.000Z').fromNow() // an hour ago || a day ago || 10 days ago

或者，如果您希望在两个特定日期之间使用，则可以使用：

var a = moment([2007, 0, 28]);
var b = moment([2007, 0, 29]);
a.from(b); // "a day ago"

取自文档：

• fromNow()
• from()

Answer 5

您需要做的就是将hours作为第二个参数传递给 moment diff 函数。

var a = moment([21,30,00], "HH:mm:ss")
var b = moment([09,30,00], "HH:mm:ss")
a.diff(b, 'hours') // 12

文档： https : //momentjs.com/docs/#/displaying/difference/

例子：

 const dateFormat = "YYYY-MM-DD HH:mm:ss"; // Get your start and end date/times const rightNow = moment().format(dateFormat); const thisTimeYesterday = moment().subtract(1, 'days').format(dateFormat); // pass in hours as the second parameter to the diff function const differenceInHours = moment(rightNow).diff(thisTimeYesterday, 'hours'); console.log(`${differenceInHours} hours have passed since this time yesterday`);

Answer 6

我知道这是旧的，但这里有一个单衬解决方案：

const hourDiff = start.diff(end, "hours");

其中开始和结束是矩对象。

享受！

Answer 7

var __startTime = moment("2016-06-06T09:00").format();
var __endTime = moment("2016-06-06T21:00").format();

var __duration = moment.duration(moment(__endTime).diff(__startTime));
var __hours = __duration.asHours();
console.log(__hours);

Answer 8

 var start=moment(1541243900000);
 var end=moment(1541243942882);
 var duration = moment.duration(end.diff(startTime));
 var hours = duration.asHours();

如您所见，开始和结束日期需要是时刻对象才能使此方法工作。

Answer 9

就我而言，我想要小时和分钟：

var duration = moment.duration(end.diff(startTime));
var hours = duration.hours(); //hours instead of asHours
var minutes = duration.minutes(); //minutes instead of asMinutes

有关更多信息，请参阅官方文档。

Answer 10

我知道这已经得到了回答，但是如果您想要递归和更通用的东西并且不依赖于 moment fromNow您可以使用我创建的这个函数。 当然，您可以更改其逻辑以根据您的需要进行调整，以支持年和秒。

var createdAt = moment('2019-05-13T14:23:00.607Z');
var expiresAt = moment('2019-05-14T14:23:00.563Z');

// You can also add years in the beginning of the array or seconds in its end
const UNITS = ["months", "weeks", "days", "hours", "minutes"]
function getValidFor (createdAt, expiresAt, unit = 'months') {
    const validForUnit = expiresAt.diff(createdAt, unit);
    // you could adjust the if to your needs 
    if (validForUnit > 1 || unit === "minutes") {
    return [validForUnit, unit];
  }
  return getValidFor(createdAt, expiresAt, UNITS[UNITS.indexOf(unit) + 1]);
}

Answer 11

根据 Moment JS 的新弃用警告

您需要传递开始和结束日期格式的格式以及值，例如：

   let trackStartTime = "2020-12-29 09:59:19.07 +05:30";
   let trackEndTime = "2020-12-29 11:04:19.07 +05:30" || moment().format("YYYY-MM-DD HH:mm:ss.SS Z");
   let overallActivity = moment.duration(moment(trackEndTime, 'YYYY-MM-DD HH:mm:ss.SS Z').diff(moment(trackStartTime, 'YYYY-MM-DD HH:mm:ss.SS Z'))).asHours();

Answer 12

你只需要在 moment.js 中使用 date.diff() 方法

 const now = moment.utc(); var end = moment("2021-09-13"); var days = now.diff(end, "days"); console.log(days)

Answer 13

如果您想要在一天中两个日期之间的总分钟数，那么下面的代码可能会对您有所帮助开始日期：2018-05-04 02:08:05 ，结束日期：2018-05-14 09:04:07 ...

function countDaysAndTimes(startDate,endDate){
return new Promise(function (resolve, reject) {
var dayObj = new Object;
var finalArray = new Array;

var datetime1 = moment(startDate);
var datetime2 = moment(endDate);
if(datetime1.format('D') != datetime2.format('D') || datetime1.format('M') != datetime2.format('M') ||  datetime1.format('YYYY') != datetime2.format('YYYY')){
  var onlyDate1 = startDate.split(" ");
  var onlyDate2 = endDate.split(" ");
  var totalDays = moment(onlyDate2[0]).diff(moment(onlyDate1[0]), 'days')

  // First Day Entry
  dayObj.startDate = startDate;
  dayObj.endDate = moment(onlyDate1[0]).add(1, 'day').format('YYYY-MM-DD')+" 00:00:00";
  dayObj.minutes = moment(dayObj.endDate).diff(moment(dayObj.startDate), 'minutes');
  finalArray.push(dayObj);

  // Between Days Entry
  var i = 1;
  if(totalDays > 1){
    for(i=1; i<totalDays; i++){
      var dayObj1 = new Object;
      dayObj1.startDate = moment(onlyDate1[0]).add(i, 'day').format('YYYY-MM-DD')+" 00:00:00";
      dayObj1.endDate = moment(onlyDate1[0]).add(i+1, 'day').format('YYYY-MM-DD')+" 00:00:00";
      dayObj1.minutes = moment(dayObj1.endDate).diff(moment(dayObj1.startDate), 'minutes');
      finalArray.push(dayObj1);
    }
  }

  // Last Day Entry
  var dayObj2 = new Object;
  dayObj2.startDate = moment(onlyDate1[0]).add(i, 'day').format('YYYY-MM-DD')+" 00:00:00";
  dayObj2.endDate = endDate ;
  dayObj2.minutes = moment(dayObj2.endDate).diff(moment(dayObj2.startDate), 'minutes');
  finalArray.push(dayObj2);

}
else{
  dayObj.startDate = startDate;
  dayObj.endDate = endDate;
  dayObj.minutes = datetime2.diff(datetime1, 'minutes');
  finalArray.push(dayObj);
}
console.log(JSON.stringify(finalArray));
// console.table(finalArray);
resolve(finalArray);
});
}

输出

          // ax bigger than 0 zero means date in past. ms less than zero is in future
