'Javascript seconds to minutes and seconds
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?
Solution 1:[1]
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.
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);
Solution 2:[2]
Another fancy solution:
function fancyTimeFormat(duration)
{
// Hours, minutes and seconds
var hrs = ~~(duration / 3600);
var mins = ~~((duration % 3600) / 60);
var secs = ~~duration % 60;
// Output like "1:01" or "4:03:59" or "123:03:59"
var ret = "";
if (hrs > 0) {
ret += "" + hrs + ":" + (mins < 10 ? "0" : "");
}
ret += "" + mins + ":" + (secs < 10 ? "0" : "");
ret += "" + secs;
return ret;
}
~~ is a shorthand for Math.floor, see this link for more info

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).

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:
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.
%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){
var 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

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(':')
}Solution 6:[6]
You can also use native Date object:
var date = new Date(null);
date.setSeconds(timeInSeconds);
// retrieve time ignoring the browser timezone - returns hh:mm:ss
var utc = date.toUTCString();
// negative start index in substr does not work in IE 8 and earlier
var time = utc.substr(utc.indexOf(':') - 2, 8)
// retrieve each value individually - returns h:m:s
var time = date.getUTCHours() + ':' + date.getUTCMinutes() + ':' + date.getUTCSeconds();
// does not work in IE8 and below - returns hh:mm:ss
var time = date.toISOString().substr(11, 8);
// not recommended - only if seconds number includes timezone difference
var time = date.toTimeString().substr(0, 8);
Of course this solution works only for timeInSeconds less than 24 hours ;)
Solution 7:[7]
function secondsToMinutes(time){
return Math.floor(time / 60)+':'+Math.floor(time % 60);
}
Solution 8:[8]
To add leading zeros, I would just do:
var minutes = "0" + Math.floor(time / 60);
var seconds = "0" + (time - minutes * 60);
return minutes.substr(-2) + ":" + seconds.substr(-2);
Nice and short

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
Solution 10:[10]
Clean one liner using ES6
const secondsToMinutes = seconds => Math.floor(seconds / 60) + ':' + ('0' + Math.floor(seconds % 60)).slice(-2);
Solution 11:[11]
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.
Solution 12:[12]
A one liner (doesnt work with hours):
function sectostr(time) {
return ~~(time / 60) + ":" + (time % 60 < 10 ? "0" : "") + time % 60;
}
Solution 13:[13]
Seconds to h:mm:ss
var hours = Math.floor(time / 3600);
time -= hours * 3600;
var minutes = Math.floor(time / 60);
time -= minutes * 60;
var seconds = parseInt(time % 60, 10);
console.log(hours + ':' + (minutes < 10 ? '0' + minutes : minutes) + ':' + (seconds < 10 ? '0' + seconds : seconds));
Solution 14:[14]
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){
ddhhmmss += Seconds + ' Seconds ';
}
return ddhhmmss;
}

After all this, yet another simple solution:
const time = new Date(null);
time.setSeconds(7530);
console.log(time.getHours(), time.getMinutes(), time.getSeconds());
Solution 16:[16]
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;
};
Solution 17:[17]
function formatSeconds(s: number) {
let minutes = ~~(s / 60);
let seconds = ~~(s % 60);
return minutes + ':' + seconds;
}
Solution 18:[18]
For adding zeros I really don't see the need to have a full other function where you can simply use for example
var mins=Math.floor(StrTime/60);
var secs=StrTime-mins * 60;
var hrs=Math.floor(StrTime / 3600);
RoundTime.innerHTML=(hrs>9?hrs:"0"+hrs) + ":" + (mins>9?mins:"0"+mins) + ":" + (secs>9?secs:"0"+secs);
Its why we have conditional statements in the first place.
(condition?if true:if false) so if example seconds is more than 9 than just show seconds else add a string 0 before it.
Solution 19:[19]
var seconds = 60;
var measuredTime = new Date(null);
measuredTime.setSeconds(seconds); // specify value of SECONDS
var Time = measuredTime.toISOString().substr(11, 8);
document.getElementById("id1").value = Time;<div class="form-group">
<label for="course" class="col-md-4">Time</label>
<div class="col-md-8">
<input type="text" class="form-control" id="id1" name="field">Min

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;
}
Solution 21:[21]
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
Solution 22:[22]
I was thinking of a faster way to get this done and this is what i came up with
var sec = parseInt(time);
var min=0;
while(sec>59){ sec-=60; min++;}
If we want to convert "time" to minutes and seconds, for example:
// time = 75,3 sec
var sec = parseInt(time); //sec = 75
var min=0;
while(sec>59){ sec-=60; min++;} //sec = 15; min = 1
Solution 23:[23]
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

time.seconds() // 40

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';
}

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!"
Solution 28:[28]
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
