</style>

Step 3 – Add JavaScript

And also copy and paste below JavaScript code between <script></script> tag.

<script>
var Cal = function (divId) {
  //Store div id
  this.divId = divId;

  // Days of week, starting on Sunday
  this.DaysOfWeek = ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"];

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

  // Set the current month, year
  var d = new Date();

  this.currMonth = d.getMonth();
  this.currYear = d.getFullYear();
  this.currDay = d.getDate();
};

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

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

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

// Show month (year, month)
Cal.prototype.showMonth = function (y, m) {
  var d = new Date(),
    // First day of the week in the selected month
    firstDayOfMonth = new Date(y, m, 1).getDay(),
    // Last day of the selected month
    lastDateOfMonth = new Date(y, m + 1, 0).getDate(),
    // Last day of the previous month
    lastDayOfLastMonth =
      m == 0 ? new Date(y - 1, 11, 0).getDate() : new Date(y, m, 0).getDate();

  var html = "<table>";

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

  // Write the header of the days of the week
  html += '<tr class="days">';
  for (var i = 0; i < this.DaysOfWeek.length; i++) {
    html += "<td>" + this.DaysOfWeek[i] + "</td>";
  }
  html += "</tr>";

  // Write the days
  var i = 1;
  do {
    var dow = new Date(y, m, i).getDay();

    // If Sunday, start new row
    if (dow == 0) {
      html += "<tr>";
    }
    // If not Sunday but first day of the month
    // it will write the last days from the previous month
    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++;
      }
    }

    // Write the current day in the loop
    var chk = new Date();
    var chkY = chk.getFullYear();
    var chkM = chk.getMonth();
    if (chkY == this.currYear && chkM == this.currMonth && i == this.currDay) {
      html += '<td class="today">' + i + "</td>";
    } else {
      html += '<td class="normal">' + i + "</td>";
    }
    // If Saturday, closes the row
    if (dow == 6) {
      html += "</tr>";
    }
    // If not Saturday, but last day of the selected month
    // it will write the next few days from the next month
    else if (i == lastDateOfMonth) {
      var k = 1;
      for (dow; dow < 6; dow++) {
        html += '<td class="not-current">' + k + "</td>";
        k++;
      }
    }

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

  // Closes table
  html += "</table>";

  // Write HTML to the div
  document.getElementById(this.divId).innerHTML = html;
};

// On Load of the window
window.onload = function () {
  // Start calendar
  var c = new Cal("divCal");
  c.showcurr();

  // Bind next and previous button clicks
  getId("btnNext").onclick = function () {
    c.nextMonth();
  };
  getId("btnPrev").onclick = function () {
    c.previousMonth();
  };
};

// Get element by id
function getId(id) {
  return document.getElementById(id);
}

</script>

At the end we will have something like this. You can change fonts, colors, backgrounds and all things that you want. Enjoy it.
