How to get difference between 2 Dates in Years, Months and days using moment.js? For example the difference between 4/5/2014 & 2/22/2013 should be calculated as 1 Year, 1 Month and 14 Days.

推荐答案

Moment.js无法直接处理此场景。它允许您获取两个时刻之间的差异，但结果是经过的持续时间（以毫秒为单位）。片刻确实有一个持续时间对象，但它将一个月定义为30天的固定单位 - 我们知道情况并非总是如此。

Moment.js can't handle this scenario directly. It does allow you to take the difference between two moments, but the result is an elapsed duration of time in milliseconds. Moment does have a Duration object, but it defines a month as a fixed unit of 30 days - which we know is not always the case.

幸运的是，已经创建了一个名为精确范围，这是正确的做法。查看来源，它有所作为类似于 torazaburo的答案 - 但它恰当地说明了要调整的月份天数。

Fortunately, there is a plugin already created for moment called "Precise Range", which does the right thing. Looking at the source, it does something similar to torazaburo's answer - but it properly accounts for the number of days in the month to adjust.

在你的项目中包含了moment.js和这个插件（readable-range.js）后，你可以这样简单地调用它：

After including both moment.js and this plugin (readable-range.js) in your project, you can simply call it like this:

var m1 = moment('2/22/2013','M/D/YYYY');
var m2 = moment('4/5/2014','M/D/YYYY');
var diff = moment.preciseDiff(m1, m2);
console.log(diff);

输出为1年1个月14天

The output is "1 year 1 month 14 days"
