How to Accurately Retrieve Hours of Difference Between Dates in Moment.js?

Retrieving Hours of Difference between Dates in Moment.js

Moment.js, a popular JavaScript library for handling dates and times, provides an elegant way to calculate the time difference between two dates. While the diff() method can readily return the difference in minutes and seconds, there may be instances where retrieving the elapsed hours is also desirable.

The diff() method of Moment.js, as illustrated in your question, can efectivamente determine the time between two dates and format it using the desired units, such as minutes and seconds. However, extracting the duration hours using the duration.hours() method can be misleading, as it returns the current hour rather than the number of elapsed hours.

To correct this, the duration.asHours() method should be employed instead. This method returns the duration in decimal format. For instance, if there are 3 hours and 30 minutes between two dates, duration.asHours() will return 3.5.

Here's a corrected code snippet:

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

This revised code will accurately extract the number of hours between the two specified dates and store it in the hours variable for further use in your application.
