JavaScript: Convert milliseconds to object with days, hours, minutes, and seconds

msconvert.js

function convertMS(ms) {
  var d, h, m, s;
  s = Math.floor(ms / 1000);
  m = Math.floor(s / 60);
  s = s % 60;
  h = Math.floor(m / 60);
  m = m % 60;
  d = Math.floor(h / 24);
  h = h % 24;
  return { d: d, h: h, m: m, s: s };
};

var timer;

var compareDate = new Date();
compareDate.setDate(compareDate.getDate() + 7); //just for this demo today + 7 days

timer = setInterval(function() {
timeBetweenDates(compareDate);
}, 1000);

function timeBetweenDates(toDate) {
var dateEntered = toDate;
var now = new Date();
var difference = dateEntered.getTime() - now.getTime();

if (difference <= 0) {

// Timer done
clearInterval(timer);

} else {

var seconds = Math.floor(difference / 1000);
var minutes = Math.floor(seconds / 60);
var hours = Math.floor(minutes / 60);
var days = Math.floor(hours / 24);

hours %= 24;
minutes %= 60;
seconds %= 60;

$("#days").text(days);
$("#hours").text(hours);
$("#minutes").text(minutes);
$("#seconds").text(seconds);

}
}

var timer;

var compareDate = new Date();
compareDate.setDate(compareDate.getDate() + 7); //just for this demo today + 7 days

timer = setInterval(function() {
timeBetweenDates(compareDate);
}, 1000);

var seconds = Math.floor(difference / 1000);
var minutes = Math.floor(seconds / 60);
var hours = Math.floor(minutes / 60);
var days = Math.floor(hours / 24);

hours %= 24;
minutes %= 60;
seconds %= 60;

$("#days").text(days);
$("#hours").text(hours);
$("#minutes").text(minutes);
$("#seconds").text(seconds);

}
}
