Convert seconds to HH-MM-SS with JavaScript?

How can I convert seconds to an HH-MM-SS string using JavaScript?

Answers


Don't you know datejs? it is a must know.

Using datejs, just write something like:

(new Date).clearTime()
          .addSeconds(15457)
          .toString('H:mm:ss');

--update

Nowadays date.js is outdated and not maintained, so use "Moment.js", which is much better as pointed out by T.J. Crowder.


You can manage to do this without any external JavaScript library with the help of JavaScript Date method like following:

var date = new Date(null);
date.setSeconds(SECONDS); // specify value for SECONDS here
var result = date.toISOString().substr(11, 8);

Or, as per @Frank's comment; a one liner:

new Date(SECONDS * 1000).toISOString().substr(11, 8);

I don't think any built-in feature of the standard Date object will do this for you in a way that's more convenient than just doing the math yourself.

hours = Math.floor(totalSeconds / 3600);
totalSeconds %= 3600;
minutes = Math.floor(totalSeconds / 60);
seconds = totalSeconds % 60;

Example:

let totalSeconds = 28565;
let hours = Math.floor(totalSeconds / 3600);
totalSeconds %= 3600;
let minutes = Math.floor(totalSeconds / 60);
let seconds = totalSeconds % 60;

console.log("hours: " + hours);
console.log("minutes: " + minutes);
console.log("seconds: " + seconds);

// If you want strings with leading zeroes:
minutes = String(minutes).padStart(2, "0");
hours = String(hours).padStart(2, "0");
seconds = String(seconds).padStart(2, "0");
console.log(hours + ":" + minutes + ":" + seconds);

As Cleiton pointed out in his answer, moment.js can be used for this:

moment().startOf('day')
        .seconds(15457)
        .format('H:mm:ss');

I know this is kinda old, but...

ES2015:

var toHHMMSS = (secs) => {
    var sec_num = parseInt(secs, 10)    
    var hours   = Math.floor(sec_num / 3600) % 24
    var minutes = Math.floor(sec_num / 60) % 60
    var seconds = sec_num % 60    
    return [hours,minutes,seconds]
        .map(v => v < 10 ? "0" + v : v)
        .filter((v,i) => v !== "00" || i > 0)
        .join(":")
}

It will output:

toHHMMSS(13545) // 03:45:45
toHHMMSS(180) // 03:00
toHHMMSS(18) // 00:18

function formatSeconds(seconds)
{
    var date = new Date(1970,0,1);
    date.setSeconds(seconds);
    return date.toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1");
}

This does the trick:

function secondstotime(secs)
{
    var t = new Date(1970,0,1);
    t.setSeconds(secs);
    var s = t.toTimeString().substr(0,8);
    if(secs > 86399)
        s = Math.floor((t - Date.parse("1/1/70")) / 3600000) + s.substr(2);
    return s;
}

(Sourced from here)


Try this:

function toTimeString(seconds) {
  return (new Date(seconds * 1000)).toUTCString().match(/(\d\d:\d\d:\d\d)/)[0];
}

     var  timeInSec = "661"; //even it can be string

            String.prototype.toHHMMSS = function () { 
               /* extend the String by using prototypical inheritance */
                var seconds = parseInt(this, 10); // don't forget the second param
                var hours   = Math.floor(seconds / 3600);
                var minutes = Math.floor((seconds - (hours * 3600)) / 60);
                seconds = seconds - (hours * 3600) - (minutes * 60);

                if (hours   < 10) {hours   = "0"+hours;}
                if (minutes < 10) {minutes = "0"+minutes;}
                if (seconds < 10) {seconds = "0"+seconds;}
                var time    = hours+':'+minutes+':'+seconds;
                return time;
            }

            alert("5678".toHHMMSS());   // "01:34:38"
            console.log(timeInSec.toHHMMSS());   //"00:11:01"

we can make this function lot shorter and crisp but that decreases the readability, so we will write it as simple as possible and as stable as possible.

or you can check this working here:


Here is an extension to Number class. toHHMMSS() converts seconds to an hh:mm:ss string.

Number.prototype.toHHMMSS = function() {
  var hours = Math.floor(this / 3600) < 10 ? ("00" + Math.floor(this / 3600)).slice(-2) : Math.floor(this / 3600);
  var minutes = ("00" + Math.floor((this % 3600) / 60)).slice(-2);
  var seconds = ("00" + (this % 3600) % 60).slice(-2);
  return hours + ":" + minutes + ":" + seconds;
}

// Usage: [number variable].toHHMMSS();

// Here is a simple test
var totalseconds = 1234;
document.getElementById("timespan").innerHTML = totalseconds.toHHMMSS();
// HTML of the test
<div id="timespan"></div>

Easy to follow version for noobies:

 var totalNumberOfSeconds = YOURNUMBEROFSECONDS;
 var hours = parseInt( totalNumberOfSeconds / 3600 );
 var minutes = parseInt( (totalNumberOfSeconds - (hours * 3600)) / 60 );
 var seconds = Math.floor((totalNumberOfSeconds - ((hours * 3600) + (minutes * 60))));
 var result = (hours < 10 ? "0" + hours : hours) + ":" + (minutes < 10 ? "0" + minutes : minutes) + ":" + (seconds  < 10 ? "0" + seconds : seconds);
 console.log(result);

This function should do it :

var convertTime = function (input, separator) {
    var pad = function(input) {return input < 10 ? "0" + input : input;};
    return [
        pad(Math.floor(input / 3600)),
        pad(Math.floor(input % 3600 / 60)),
        pad(Math.floor(input % 60)),
    ].join(typeof separator !== 'undefined' ?  separator : ':' );
}

Without passing a separator, it uses : as the (default) separator :

time = convertTime(13551.9941351); // --> OUTPUT = 03:45:51

If you want to use - as a separator, just pass it as the second parameter:

time = convertTime(1126.5135155, '-'); // --> OUTPUT = 00-18-46

See also this Fiddle.


Chiming in on this old thread -- the OP stated HH:MM:SS, and many of the solutions work, until you realize you need more than 24 hours listed. And maybe you don't want more than a single line of code. Here you go:

d=(s)=>{f=Math.floor;g=(n)=>('00'+n).slice(-2);return f(s/3600)+':'+g(f(s/60)%60)+':'+g(s%60)}

It returns H+:MM:SS. To use it, simply use:

d(91260);     // returns "25:21:00"
d(960);       // returns "0:16:00"

...I tried to get it to use the least amount of code possible, for a nice one-liner approach.


below is the given code which will convert seconds into hh-mm-ss format:

var measuredTime = new Date(null);
measuredTime.setSeconds(4995); // specify value of SECONDS
var MHSTime = measuredTime.toISOString().substr(11, 8);

        break;
        //More cases to meet your requirements.
    }
}

I just wanted to give a little explanation to the nice answer above:

var totalSec = new Date().getTime() / 1000;
var hours = parseInt( totalSec / 3600 ) % 24;
var minutes = parseInt( totalSec / 60 ) % 60;
var seconds = totalSec % 60;

var result = (hours < 10 ? "0" + hours : hours) + "-" + (minutes < 10 ? "0" + minutes : minutes) + "-" + (seconds  < 10 ? "0" + seconds : seconds);

On the second line, since there are 3600 seconds in 1 hour, we divide the total number of seconds by 3600 to get the total number of hours. We use parseInt to strip off any decimal. If totalSec was 12600 (3 and half hours), then parseInt( totalSec / 3600 ) would return 3, since we will have 3 full hours. Why do we need the % 24 in this case? If we exceed 24 hours, let's say we have 25 hours (90000 seconds), then the modulo here will take us back to 1 again, rather than returning 25. It is confining the result within a 24 hour limit, since there are 24 hours in one day.

When you see something like this:

25 % 24

Think of it like this:

25 mod 24 or what is the remainder when we divide 25 by 24

Have you tried adding seconds to a Date object?

var dt = new Date();
dt.addSeconds(1234);

Here is a function to convert seconds to hh-mm-ss format based on powtac's answer here

jsfiddle

/** 
 * Convert seconds to hh-mm-ss format.
 * @param {number} totalSeconds - the total seconds to convert to hh- mm-ss
**/
var SecondsTohhmmss = function(totalSeconds) {
  var hours   = Math.floor(totalSeconds / 3600);
  var minutes = Math.floor((totalSeconds - (hours * 3600)) / 60);
  var seconds = totalSeconds - (hours * 3600) - (minutes * 60);

  // round seconds
  seconds = Math.round(seconds * 100) / 100

  var result = (hours < 10 ? "0" + hours : hours);
      result += "-" + (minutes < 10 ? "0" + minutes : minutes);
      result += "-" + (seconds  < 10 ? "0" + seconds : seconds);
  return result;
}

Example use

var seconds = SecondsTohhmmss(70);
console.log(seconds);
// logs 00-01-10

After looking at all the answers and not being happy with most of them, this is what I came up with. I know I am very late to the conversation, but here it is anyway.

function secsToTime(secs){
  var time = new Date(); 
  // create Date object and set to today's date and time
  time.setHours(parseInt(secs/3600) % 24);
  time.setMinutes(parseInt(secs/60) % 60);
  time.setSeconds(parseInt(secs%60));
  time = time.toTimeString().split(" ")[0];
  // time.toString() = "HH:mm:ss GMT-0800 (PST)"
  // time.toString().split(" ") = ["HH:mm:ss", "GMT-0800", "(PST)"]
  // time.toTimeString().split(" ")[0]; = "HH:mm:ss"
  return time;
}

I create a new Date object, change the time to my parameters, convert the Date Object to a time string, and removed the additional stuff by splitting the string and returning only the part that need.

I thought I would share this approach, since it removes the need for regex, logic and math acrobatics to get the results in "HH:mm:ss" format, and instead it relies on built in methods.

You may want to take a look at the documentation here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date


There are lots of options of solve this problem, and obvious there are good option suggested about, But I wants to add one more optimized code here

function formatSeconds(sec) {
     return [(sec / 3600), ((sec % 3600) / 60), ((sec % 3600) % 60)]
            .map(v => v < 10 ? "0" + parseInt(v) : parseInt(v))
            .filter((i, j) => i !== "00" || j > 0)
            .join(":");
}

if you don't wants formatted zero with less then 10 number, you can use

function formatSeconds(sec) {
  return parseInt(sec / 3600) + ':' + parseInt((sec % 3600) / 60) + ':' + parseInt((sec % 3600) % 60);

}

Sample Code http://fiddly.org/1c476/1


In one line, using T.J. Crowder's solution :

secToHHMMSS = seconds => `${Math.floor(seconds / 3600)}:${Math.floor((seconds % 3600) / 60)}:${Math.floor((seconds % 3600) % 60)}`

In one line, another solution that also count days :

secToDHHMMSS = seconds => `${parseInt(seconds / 86400)}d ${new Date(seconds * 1000).toISOString().substr(11, 8)}`

Source : https://gist.github.com/martinbean/2bf88c446be8048814cf02b2641ba276


var sec_to_hms = function(sec){
var min, hours;
     sec = sec - (min = Math.floor(sec/60))*60;
     min = min - (hours = Math.floor(min/60))*60;
     return (hours?hours+':':'') + ((min+'').padStart(2, '0')) + ':'+ ((sec+'').padStart(2, '0'));
}
alert(sec_to_hms(2442542));

You can also use below code:

int ss = nDur%60;
nDur   = nDur/60;
int mm = nDur%60;
int hh = nDur/60;

For anyone using AngularJS, a simple solution is to filter the value with the date API, which converts milliseconds to a string based on the requested format. Example:

<div>Offer ends in {{ timeRemaining | date: 'HH:mm:ss' }}</div>

Note that this expects milliseconds, so you may want to multiply timeRemaining by 1000 if you are converting from seconds (as the original question was formulated).


String.prototype.toHHMMSS = function () {
    var sec_num = parseInt(this, 10); // don't forget the second param
    var hours   = Math.floor(sec_num / 3600);
    var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
    var seconds = sec_num - (hours * 3600) - (minutes * 60);

    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}
    return hours+':'+minutes+':'+seconds;
}

Usage Example

alert("186".toHHMMSS());

I've used this code before to create a simple timespan object:

function TimeSpan(time) {
this.hours = 0;
this.minutes = 0;
this.seconds = 0;

while(time >= 3600)
{
    this.hours++;
    time -= 3600;
}

while(time >= 60)
{
    this.minutes++;
    time -= 60;
}

this.seconds = time;
}

var timespan = new Timespan(3662);

new Date().toString().split(" ")[4];

result 15:08:03


I ran into the case some have mentioned where the number of seconds is more than a day. Here's an adapted version of @Harish Anchu's top-rated answer that accounts for longer periods of time:

function secondsToTime(seconds) {
  const arr = new Date(seconds * 1000).toISOString().substr(11, 8).split(':');

  const days = Math.floor(seconds / 86400);
  arr[0] = parseInt(arr[0], 10) + days * 24;

  return arr.join(':');
}

Example:

secondsToTime(101596) // outputs '28:13:16' as opposed to '04:13:16'

Maybe something like this:

var Convert = function (time) {
    const HOUR = 60 * 60;
    const MINUTE = 60;

    var minutesInSeconds = time % HOUR;
    var hours = Math.floor(time / HOUR);
    var minutes = Math.floor(minutesInSeconds / MINUTE)
    var seconds = minutesInSeconds % MINUTE;

    return hours.padStart(2, 0) + ':' + minutes.padStart(2, 0) + ':' + seconds.padStart(2, 0);
}

You can also use Sugar.

Date.create().reset().set({seconds: 180}).format('{mm}:{ss}');

This example returns '03:00'.
