This HTML code snippet helps you to create a clock and calendar widget. It comes with a flippable card that consists of two faces. On the “front” face, there is a time widget with a square outer. On the “back” face, there is a calendar with two buttons labeled “Prev” and “Next” to navigate the dates.

How to Create Clock and Calendar Widget in HTML

First of all, load the Google fonts and Font Awesome CSS by adding the following assets into the head tag of your HTML document.

<link rel='stylesheet' href='//fonts.googleapis.com/css?family=Roboto+Slab:100,300,400'>
<link rel='stylesheet' href='//maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css'>

Now, create the HTML structure for the clock and calendar as follows:

<div class="container">
  <div class="flip-container" ontouchstart="this.classList.toggle('hover');">
    <div class="flipper">
      <div class="front">
        <div id="time-widget" class="outer-square setter time">
          <div id="do-time"></div>
        </div>
      </div>
      <div class="back">
        <div class="calendar-wrapper">
          <button id="btnPrev" type="button">Prev</button>
          <button id="btnNext" type="button">Next</button>
          <div id="divCal"></div>
        </div>
      </div>
    </div>
  </div>
</div>

Now, style the clock and calendar widget using the following CSS styles:

html,
body {
  height: 100%;
}
body {
  font-size: 100%;
  line-height: 1.5;

Load the jQuery by adding the following CDN link before closing the body tag:

<script src='//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js'></script>

Finally, add the following JavaScript function to activate the clock:

setInterval(function(){
  getId("do-time").innerHTML = formatTime();
},1000);

function formatTime() {

  var d = new Date(),
      minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(),
      hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(),
      ampm = d.getHours() >= 12 ? 'pm' : 'am',
      months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'],
      days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];

  return '<h2>'+hours+'<span>:'+minutes+'</span></h2><small>'+ampm+'</small><h3>'+days[d.getDay()]+'<span>'+months[d.getMonth()]+' '+d.getDate()+'</span>'+d.getFullYear()+'</h3>';
}

var Cal = function(divId) {

  this.divId = divId;

  this.DaysOfWeek = [ 'Su', 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa' ];

  this.Months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December' ];

  var d = new Date();

  this.currMonth = d.getMonth();
  this.currYear = d.getFullYear();
  this.currDate = d.getDate();
  this.currD = d.getDay();

};

Cal.prototype.nextMonth = function() {
  if ( this.currMonth == 11 ) {
    this.currMonth = 0;
    this.currYear = this.currYear + 1;
  }
  else {
    this.currMonth = this.currMonth + 1;
  }
  this.showcurr();
};

Cal.prototype.previousMonth = function() {
  if ( this.currMonth == 0 ) {
    this.currMonth = 11;
    this.currYear = this.currYear - 1;
  }
  else {
    this.currMonth = this.currMonth - 1;
  }
  this.showcurr();
};

Cal.prototype.showcurr = function() {
  this.showMonth(this.currYear, this.currMonth);
};

Cal.prototype.showMonth = function(y, m) {

  var chk = new Date();
  var chkY = chk.getFullYear();
  var chkM = chk.getMonth();

  var d = new Date()
  , firstDayOfMonth = new Date(y, m, 1).getDay()
  , lastDateOfMonth =  new Date(y, m+1, 0).getDate()
  , lastDayOfLastMonth = m == 0 ? new Date(y-1, 11, 0).getDate() : new Date(y, m, 0).getDate();


  var html = '<table>';

  html += '<thead><tr>';
  html += '<td colspan="7">' + this.Months[m] + ' ' + y + '</td>';
  html += '</tr></thead>';


  html += '<tr class="days">';
  for(var i=0; i < this.DaysOfWeek.length;i++) {
    if ( chkY == this.currYear && chkM == this.currMonth && i == this.currD ) {
      html += '<td class="today">' + this.DaysOfWeek[i] + '</td>';
    } else {
      html += '<td>' + this.DaysOfWeek[i] + '</td>';
    }
  }
  html += '</tr>';

  var i=1;
  do {

    var dow = new Date(y, m, i).getDay();

    if ( dow == 0 ) {
      html += '<tr>';
    }
    else if ( i == 1 ) {
      html += '<tr>';
      var k = lastDayOfLastMonth - firstDayOfMonth+1;
      for(var j=0; j < firstDayOfMonth; j++) {
        html += '<td class="not-current">' + k + '</td>';
        k++;
      }
    }

    if (chkY == this.currYear && chkM == this.currMonth && i == this.currDate) {
      html += '<td class="today">' + i + '</td>';
    } else {
      html += '<td class="normal">' + i + '</td>';
    }
    if ( dow == 6 ) {
      html += '</tr>';
    }
    else if ( i == lastDateOfMonth ) {
      var k=1;
      for(dow; dow < 6; dow++) {
        html += '<td class="not-current">' + k + '</td>';
        k++;
      }
    }

    i++;
  }while(i <= lastDateOfMonth);

  html += '</table>';

  document.getElementById(this.divId).innerHTML = html;
};

window.onload = function() {
