</div>

Пишем стиль:

CSS:

@import url('https://fonts.googleapis.com/css?family=Limelight|Mada');
*,
*:before,
*:after {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

body {
  background: #000;
}

.container {
  width: 750px;
  text-align: center;
  position: absolute;
  transform: translate(-50%, -50%);
  top: 50%;
  left: 50%;
  font-family: 'Mada', sans-serif;
}

.intro {
  margin: 5% auto;
  color: #9e8686;
}

.countdown-wrapper {
  display: flex;
  justify-content: space-around;
  margin: 5% auto;
  color: #7e8c6a;
}

label,
output,
.time-el span {
  display: block;
}

.time-el .digit{
  position: relative;
  width: 70px;
  height: 100px;
  display: inline-block;
  font-size: 90px;
  line-height: 100px;
  font-family: 'Limelight', cursive;
  border: 2px solid;
  margin: 4px;
  border-radius: 5px;
}

.inner {
  height: 200%;
  width: 100%;
  position: absolute;
}

.top .inner {
  top: 0;
}

.bottom .inner {
  bottom: 0;
}
.time-el .top, .time-el .bottom {
  position: absolute;
  left: 0;
  height: 50%;
  width: 100%;
  overflow: hidden;
}

.time-el .top {
  top: 0;
  transform-origin: 50% 100%;
}

.time-el .bottom {
  bottom: 0;
  transform-origin: 50% 0%;
}

.time-el label{
  font-size: 10px;
  letter-spacing: 1px;
  color: #9e8686;
}

Пишем jquery:

JavaScript:

var targetTime = new Date("Jan 1, 2019");
var seconds = 1000;
var minutes = seconds * 60;
var hours = minutes * 60;
var days = hours * 24;
var $daysEl = $(".time-el #days");
var $hoursEl = $(".time-el #hours");
var $minutesEl = $(".time-el #minutes");
var $secondsEl = $(".time-el #seconds");

function startCountDown() {
  updateTick();
  var timeInterval = setInterval(updateTick, seconds);

  function updateTick() {
    var timeLeft = Date.parse(targetTime) - Date.parse(new Date());
    var spanContent = '<span class="digit"><span class="top"><span class="inner">$1</span></span><span class="bottom"><span class="inner">$1</span></span></span>';
    $daysEl.html(Math.floor(timeLeft / days)).html(function (i, digit) {return digit.replace(/(\d)/g, spanContent);});
    $hoursEl.html(("0" + Math.floor(timeLeft % days / hours)).slice(-2)).html(function (i, digit) {return digit.replace(/(\d)/g, spanContent);});
    $minutesEl.html(("0" + Math.floor(timeLeft % hours / minutes)).slice(-2)).html(function (i, digit) {return digit.replace(/(\d)/g, spanContent);});
    $secondsEl.html(("0" + Math.floor(timeLeft % minutes / seconds)).slice(-2)).html(function (i, digit) {return digit.replace(/(\d)/g, spanContent);});
    if (timeLeft <= 0) clearInterval(timeInterval);
  }
}

$(function () {
  startCountDown();
});
