Get hours difference between two dates in Moment Js

Question

I'm able to get the difference between two dates using MomentJs as follows:

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

However, I also want to display the hour when applicable (only when >= 60 minutes have passed).

However, when I try to retrieve the duration hours using the following:

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

it is returning the current hour and not the number of hours between the two dates.

How do I get the difference in hours between two Moments?

Answer 1

You were close. You just need to use the duration.asHours() method (see the docs).

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

Answer 2

Following code block shows how to calculate the difference in number of days between two dates using MomentJS.

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)
