Javascript seconds to minutes and seconds

Question

Hey,

This is a common problem but I'm not sure how to solve it. The code below works fine.

var mind = time % (60 * 60);
var minutes = Math.floor(mind / 60);

var secd = mind % 60;
var seconds = Math.ceil(secd);

However, when I get to 1 hour or 3600 seconds it returns 0 minutes and 0 seconds. How can I avoid this so it returns all the minutes?

Thanks

Answer 1

You’re doing to wrong. To get the number of full minutes, divide the number of total seconds by 60 (60 seconds/minute):

var minutes = Math.floor(time / 60);

And to get the remaining seconds, multiply the full minutes with 60 and subtract from the total seconds:

var seconds = time - minutes * 60;

Now if you also want to get the full hours too, divide the number of total seconds by 3600 (60 minutes/hour · 60 seconds/minute) first, then calculate the remaining seconds:

var hours = Math.floor(time / 3600);
time = time - hours * 3600;

Then you calculate the full minutes and remaining seconds.

Answer 2

You've done enough code to track minutes and seconds portions of time.

What you could do is add the hours factor in:

var hrd = time % (60 * 60 * 60);
var hours = Math.floor(hrd / 60);

var mind = hrd % 60;
var minutes = Math.floor(mind / 60);

var secd = mind % 60;
var seconds = Math.ceil(secd);

var moreminutes = minutes + hours * 60

This would give you what you need also.
