How to calculate elapsed time in JavaScript?

in JavaScript on April 1, 2021

I am going to make use of same function I created in this post:

How to create a simple stopwatch using JavaScript?

Let’s modify the code in the post above slightly to get what we want.


We’re going to show hours, minutes and seconds elapsed. You can add microseconds as well, just like the stopwatch example or just keep minutes and seconds.


Let’s give it a nice look using CSS. It’s not required for background processing for e.g. if you want to keep track of user’s timing activities.


Finally, let’s add the modified JavaScript function.

Here’s the demo and JavaScript code.
