Javascript seconds to minutes and seconds

by

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 ยท 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.

Bonus:

Use the following code to pretty-print the time (suggested by Dru)

function str_pad_left(string,pad,length) {
    return (new Array(length+1).join(pad)+string).slice(-length);
}

var finalTime = str_pad_left(minutes,'0',2)+':'+str_pad_left(seconds,'0',2);
