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?

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();
