现在数据中moment.js错误

Question

I have this code:

 var utc = moment.tz(1521221491000, "UTC"); var local = utc.clone().tz(moment.tz.guess()); console.log(moment([2018, 03, 15]).fromNow()); console.log('moment() piece by piece: ' + moment().get('year') + ' ' + moment().get('month') + ' ' + moment().get('date') + '. Data inside of momment: ' + moment().format()); console.log(local.format("YYYY-MM-DD HH:MM:SS")); 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.21.0/moment.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.14/moment-timezone-with-data.js"></script> 

In the line 3

console.log(moment([2018, 03, 15]).fromNow());

Suppose to say '1 day ago', at the moment to write this question is 16 of March 2018... And for some reason the response is

in a month...

Any idea why this error, the error is in the month var.

Answer 1

Moment使用与JavaScript Date对象相同的（讨厌的）日期系统，其中January = 0，February = 1，依此类推。因此3表示April，这是从现在开始的一个月。

Answer 2

As indicated in moment's documentation , when parsing an array as the argument, moment mirrors the native javascript Date object's 0-based indexing for months. So 3 is, confusingly, April.

I personally find it's much easier to have moment parse pre-formatted string or objects, though your mileage may vary.

Answer 3

Like answered by Gnagy in this thread ( https://stackoverflow.com/a/20094956/8733102 ),

According to the documentation , months are zero indexed. So January is 0 and December is 11.
