Javascript seconds to minutes and seconds

Question

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?

Answer 1

console.log(mmSS(01), mmSS(60), mmSS(61)); // 00:01, 1:00, 1:01
console.log(mmSS(01, true), mmSS(5, true), mmSS(5.5, true)); // mins: 01:00, 5:00, 5:30
console.log(mmSS(119), mmSS(120), mmSS(121)); // 1:59, 2:00, 2:01
console.log(mmSS(599), mmSS(600), mmSS(601)); // 9:59, 10:00, 10:01
console.log(mmSS(3599), mmSS(3600), mmSS(3601)); // 59:59, 1:00:00, 1:00:01
console.log(mmSS(35999), mmSS(36000), mmSS(36001)); // 9:59:59, 10:00:00, 10:00:01


function mmSS(duration, isValueInMinsFormat = false) 
{
  if (isValueInMinsFormat) {
    // Convert minutes to seconds
    duration *= 60;
  }

  // Calculate minutes and seconds
  const minutes = Math.floor(duration / 60);
  const seconds = duration % 60;

  // Format the result as MM:SS
  return `${String(minutes).padStart(2, '0')}:${String(seconds).padStart(2, '0')}`;
}

Answer 2

const totalSeconds = 565;

// 👇️ get the number of full minutes

const minutes = Math.floor(totalSeconds / 60);

// 👇️ get the remainder of the seconds

const seconds = totalSeconds % 60;

function padTo2Digits(num) {
  return num.toString().padStart(2, '0');
}

// ✅ format as MM:SS

const result = `${padTo2Digits(minutes)}:${padTo2Digits(seconds)}`;
console.log(result); // 👉️ "09:25"

Answer 3

If you're after a formatted mm:ss time string, you can use the Date constructor and toLocaleTimeString():

const seconds = 157;

const timeString = new Date(seconds * 1000).toLocaleTimeString([], {
  minute: "numeric",
  second: "2-digit",
})

console.log(timeString);

Note that:

• we create a new Date object using milliseconds, seconds * 1000: the Date constructor accepts a timestamp. Effectively, we're creating a date that is a few minutes after January 1st, 1970, 00:00:00 UTC. (But day doesn't matter, since we only use time)
• the first parameter of toLocaleTimeString receives a string or array of locales. If left undefined, the user agent's default locale will be used
• the second parameter takes a DateTimeFormat options object. In our case, if we want mm:ss (without leading zero for minutes), we pass { minute: "numeric", second: "2-digit" }. (If you're still seeing a leading zero for minutes, refer to this question and this answer.)

Answer 4

2023 update:

To add leading zeros, I would just do:

const secondsToMinSecPadded = time => {
  const minutes = `${Math.floor(time / 60)}`.padStart(2, "0");
  const seconds = `${time - minutes * 60}`.padStart(2, "0");
  return `${minutes}:${seconds}`;
};


console.log(secondsToMinSecPadded(241));

Nice and short

Answer 5

This Workes for Me

 const start_date=moment().subtract(1,"days")
 const end_date=moment()

 const diff = end_date.diff(start_date, "seconds");
 var mind = diff % (60 * 60);

 const hours = Math.floor(diff / (60 * 60));
 const minutes = Math.floor(mind / 60);
 var seconds = Math.ceil(mind % 60);

 console.log("Diff===>", diff, hours, minutes, seconds);

..................Happy Codding...............

Answer 6

Another fancy solution:

function fancyTimeFormat(duration) {
  // Hours, minutes and seconds
  const hrs = ~~(duration / 3600);
  const mins = ~~((duration % 3600) / 60);
  const secs = ~~duration % 60;

  // Output like "1:01" or "4:03:59" or "123:03:59"
  let ret = "";

  if (hrs > 0) {
    ret += "" + hrs + ":" + (mins < 10 ? "0" : "");
  }

  ret += "" + mins + ":" + (secs < 10 ? "0" : "");
  ret += "" + secs;

  return ret;
}

console.log(
  fancyTimeFormat(1),
  fancyTimeFormat(10),
  fancyTimeFormat(100),
  fancyTimeFormat(1000),
  fancyTimeFormat(10000),
);

~~ is a shorthand for Math.floor, see this link for more info

Answer 7

To get the number of full minutes, divide the number of total seconds by 60 (60 seconds/minute):

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

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

const 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:

const 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);
}

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

Answer 8

if you need to work with the result easily later this is what I use:

function seconds2hms(seconds, milliseconds) {
if(milliseconds) {
    seconds = Math.floor(seconds/1000);
}
return {h:~~(seconds / 3600),m:~~((seconds % 3600) / 60),s:~~seconds % 60}

}

(used Vishal's code)

Answer 9

Here's an ES6 version of the seconds to minutes and seconds conversion, with padding (00:00 format). It only accepts integer values for seconds and ~~(x) is the shorthand floor operation.

const padTime = n => ("" + n).padStart(2, 0);
const secondsToMinSec = time =>
  `${padTime(~~(time / 60))}:${padTime(time - ~~(time / 60) * 60)}`
;

for (let i = 0; i < 10; i++) {
  const seconds = ~~(Math.random() * 300);
  console.log(seconds, secondsToMinSec(seconds));
}

Answer 10

I prefer thinking of Millisecond as its own unit, rather than as a subunit of something else. In that sense, it will have values of 0-999, so you're going to want to Pad three instead of two like I have seen with other answers. Here is an implementation:

function format(n) {
   let mil_s = String(n % 1000).padStart(3, '0');
   n = Math.trunc(n / 1000);
   let sec_s = String(n % 60).padStart(2, '0');
   n = Math.trunc(n / 60);
   return String(n) + ' m ' + sec_s + ' s ' + mil_s + ' ms';
}

console.log(format(241));

Answer 11

2020 UPDATE

Using basic math and simple javascript this can be done in just a few lines of code.

EXAMPLE - Convert 7735 seconds to HH:MM:SS.

---

MATH:

Calculations use:

1. Math.floor() - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor

The Math.floor() function returns the largest integer less than or equal to a given number.

2. % arithmetic operator (Remainder) - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Remainder

The remainder operator returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend.

Check out code below. Seconds are divided by 3600 to get number of hours and a remainder, which is used to calculate number of minutes and seconds.

HOURS => 7735 / 3600 = 2 remainder 535

MINUTES => 535 / 60 = 8 remainder 55

SECONDS => 55

---

LEADING ZEROS:

Many answers here use complicated methods to show number of hours, minutes and seconds in a proper way with leading zero - 45, 04 etc. This can be done using padStart(). This works for strings so the number must be converted to string using toString().

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/padStart

The padStart() method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of the current string.

---

CODE:

function secondsToTime(e){
    const h = Math.floor(e / 3600).toString().padStart(2,'0'),
          m = Math.floor(e % 3600 / 60).toString().padStart(2,'0'),
          s = Math.floor(e % 60).toString().padStart(2,'0');
    
    return h + ':' + m + ':' + s;
    //return `${h}:${m}:${s}`;
}

console.log(secondsToTime(7735));  // 02:08:55

/*
secondsToTime(SECONDS) // HH:MM:SS 

secondsToTime(8)       // 00:00:08 
secondsToTime(68)      // 00:01:08
secondsToTime(1768)    // 00:29:28
secondsToTime(3600)    // 01:00:00
secondsToTime(5296)    // 01:28:16
secondsToTime(7735)    // 02:08:55
secondsToTime(45296)   // 12:34:56
secondsToTime(145296)  // 40:21:36
secondsToTime(1145296) // 318:08:16
*/

Answer 12

1 - Get rest of division using %. Now you have the seconds that don't complete a minute 2 - Subtract the seconds obtained in step 1 from the total. Now you have the minutes

For example, let's assume you have 700 seconds:

seconds = 700%60); //40 seconds
minutes = (700 - (700%60))/60; //11
//11:40

Answer 13

Try this:
Converting Second to HOURS, MIN and SEC.

function convertTime(sec) {
    var hours = Math.floor(sec/3600);
    (hours >= 1) ? sec = sec - (hours*3600) : hours = '00';
    var min = Math.floor(sec/60);
    (min >= 1) ? sec = sec - (min*60) : min = '00';
    (sec < 1) ? sec='00' : void 0;

    (min.toString().length == 1) ? min = '0'+min : void 0;    
    (sec.toString().length == 1) ? sec = '0'+sec : void 0;    
    
    return hours+':'+min+':'+sec;
}

Answer 14

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

Answer 15

strftime.js (strftime github) is one of the best time formatting libraries. It's extremely light - 30KB - and effective. Using it you can convert seconds into time easily in one line of code, relying mostly on the native Date class.

When creating a new Date, each optional argument is positional as follows:

new Date(year, month, day, hours, minutes, seconds, milliseconds);

So if you initialize a new Date with all arguments as zero up to the seconds, you'll get:

var seconds = 150;
var date = new Date(0,0,0,0,0,seconds);
=> Sun Dec 31 1899 00:02:30 GMT-0500 (EST)

You can see that 150 seconds is 2-minutes and 30-seconds, as seen in the date created. Then using an strftime format ("%M:%S" for "MM:SS"), it will output your minutes' string.

var mm_ss_str = strftime("%M:%S", date);
=> "02:30"

In one line, it would look like:

var mm_ss_str = strftime('%M:%S', new Date(0,0,0,0,0,seconds));
=> "02:30"

Plus this would allow you to interchangeable support HH:MM:SS and MM:SS based on the number of seconds. For example:

# Less than an Hour (seconds < 3600)
var seconds = 2435;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "40:35"

# More than an Hour (seconds >= 3600)
var seconds = 10050;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "02:47:30"

And of course, you can simply pass whatever format you want to strftime if you want the time string to be more or less semantic.

var format = 'Honey, you said you\'d be read in %S seconds %M minutes ago!';
strftime(format, new Date(0,0,0,0,0,1210));
=> "Honey, you said you'd be read in 10 seconds 20 minutes ago!"

Answer 16

Day.js

If you use day.js, try this.

const dayjs = require('dayjs')
const duration = require('dayjs/plugin/duration') 
dayjs.extend(duration)

const time = dayjs.duration(100, 'seconds')

time.seconds() // 40
time.minutes() // 1
time.format('mm:ss') // 01:40

Answer 17

  function formatSeconds(s: number) {
    let minutes = ~~(s / 60);
    let seconds = ~~(s % 60);
    return minutes + ':' + seconds;
  }

Answer 18

The most concise method I found can be done using in just one line:

let timeString = `${timeInSeconds/60|0}:${timeInSeconds%60}`

---

Explanation

`${...}`
Template literals. Allows for expressions to be converted into a string from within the string itself.
Note: Incompatible with IE.

timeInSeconds/60|0
Takes the seconds and converts in into minutes (/60). This gives a rational number. From here it is truncated using the bitwise OR (|0)

timeInSeconds%60
Remainder (modulo). Gives the remainder of the variable divided by 60.

---

Hours

This method can be expanded to include hours like this:

let timeString = `${timeInSeconds/60/60|0}:${timeInSeconds/60%60|0}:${timeInSeconds%60}`

Repeating this process, you can even include days.

Answer 19

Moment.js

If you are using Moment.js then you can use there built in Duration object

const duration = moment.duration(4825, 'seconds');

const h = duration.hours(); // 1
const m = duration.minutes(); // 20
const s = duration.seconds(); // 25

Answer 20

2019 best variant

Format hh:mm:ss

console.log(display(60 * 60 * 2.5 + 25)) // 2.5 hours + 25 seconds

function display (seconds) {
  const format = val => `0${Math.floor(val)}`.slice(-2)
  const hours = seconds / 3600
  const minutes = (seconds % 3600) / 60

  return [hours, minutes, seconds % 60].map(format).join(':')
}

Answer 21

After all this, yet another simple solution:

const time = new Date(null);
time.setSeconds(7530);
console.log(time.getHours(), time.getMinutes(), time.getSeconds());

Answer 22

Clean one liner using ES6

const secondsToMinutes = seconds => Math.floor(seconds / 60) + ':' + ('0' + Math.floor(seconds % 60)).slice(-2);

Answer 23

The Following function will help you to get Days , Hours , Minutes , seconds

toDDHHMMSS(inputSeconds){
        const Days = Math.floor( inputSeconds / (60 * 60 * 24) );
        const Hour = Math.floor((inputSeconds % (60 * 60 * 24)) / (60 * 60));
        const Minutes = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) / 60 );
        const Seconds = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) % 60 );
        let ddhhmmss  = '';
        if (Days > 0){
            ddhhmmss += Days + ' Day ';
        }
        if (Hour > 0){
            ddhhmmss += Hour + ' Hour ';
        }

        if (Minutes > 0){
            ddhhmmss += Minutes + ' Minutes ';
        }

        if (Seconds > 0){

export function TrainingTime(props) {
    const {train_time } = props;
    const hours = Math.floor(train_time/3600);
    const minutes = Math.floor((train_time-hours * 3600) / 60);
    const seconds = Math.floor((train_time%60));

    return `${hours} hrs  ${minutes} min  ${seconds} sec`;
}

Answer 26

Another but much more elegant solution for this is as follows:

/**
 * Convert number secs to display time
 *
 * 65 input becomes 01:05.
 *
 * @param Number inputSeconds Seconds input.
 */
export const toMMSS = inputSeconds => {
    const secs = parseInt( inputSeconds, 10 );
    let minutes = Math.floor( secs / 60 );
    let seconds = secs - minutes * 60;

    if ( 10 > minutes ) {
        minutes = '0' + minutes;
    }
    if ( 10 > seconds ) {
        seconds = '0' + seconds;
    }

    // Return display.
    return minutes + ':' + seconds;
};

Answer 27

function secondsToMinutes(time){
    return Math.floor(time / 60)+':'+Math.floor(time % 60);
}

Answer 28

Put my two cents in :

function convertSecondsToMinutesAndSeconds(seconds){
            var minutes;
            var seconds;
            minutes = Math.floor(seconds/60);
            seconds = seconds%60;

            return [minutes, seconds];
        }

So this :

var minutesAndSeconds = convertSecondsToMinutesAndSeconds(101);

Will have the following output :

[1,41];

Then you can print it like so :

console.log('TIME : ' +  minutesSeconds[0] + ' minutes, ' + minutesSeconds[1] + ' seconds');

//TIME : 1 minutes, 41 seconds

Answer 29

A one liner (doesnt work with hours):

 function sectostr(time) {
    return ~~(time / 60) + ":" + (time % 60 < 10 ? "0" : "") + time % 60;
 }

Answer 30

For people dropping in hoping for a quick simple and thus short solution to format seconds into M:SS :

function fmtMSS(s){return(s-(s%=60))/60+(9<s?':':':0')+s}

done..
The function accepts either a Number (preferred) or a String (2 conversion 'penalties' which you can halve by prepending + in the function call's argument for s as in: fmtMSS(+strSeconds)), representing positive integer seconds s as argument.

Examples:

fmtMSS(    0 );  //   0:00
fmtMSS(   '8');  //   0:08
fmtMSS(    9 );  //   0:09
fmtMSS(  '10');  //   0:10
fmtMSS(   59 );  //   0:59
fmtMSS( +'60');  //   1:00
fmtMSS(   69 );  //   1:09
fmtMSS( 3599 );  //  59:59
fmtMSS('3600');  //  60:00
fmtMSS('3661');  //  61:01
fmtMSS( 7425 );  // 123:45

Breakdown:

function fmtMSS(s){   // accepts seconds as Number or String. Returns m:ss
  return( s -         // take value s and subtract (will try to convert String to Number)
          ( s %= 60 ) // the new value of s, now holding the remainder of s divided by 60 
                      // (will also try to convert String to Number)
        ) / 60 + (    // and divide the resulting Number by 60 
                      // (can never result in a fractional value = no need for rounding)
                      // to which we concatenate a String (converts the Number to String)
                      // who's reference is chosen by the conditional operator:
          9 < s       // if    seconds is larger than 9
          ? ':'       // then  we don't need to prepend a zero
          : ':0'      // else  we do need to prepend a zero
        ) + s ;       // and we add Number s to the string (converting it to String as well)
}

Note: Negative range could be added by prepending (0>s?(s=-s,'-'):'')+ to the return expression (actually, (0>s?(s=-s,'-'):0)+ would work as well).
