Minimal Calendar UI Generator In Vanilla JavaScript

Generate a minimal, clean, easy-to-style calendar using plain JavaScript and HTML.

It uses the built-in Date() function to generate the calendar, which means it will automatically update with the current date and time.

How to use it:

1. Code the HTML for the calendar.

<!-- Calendar -->
<h3 id="monthAndYear"></h3>
<table class="table table-bordered table-responsive-sm" id="calendar">
  <thead>
  <tr>
    <th>Sun</th>
    <th>Mon</th>
    <th>Tue</th>
    <th>Wed</th>
    <th>Thu</th>
    <th>Fri</th>
    <th>Sat</th>
  </tr>
  </thead>
  <tbody id="calendar-body">
  </tbody>
</table>
<!-- Prev/next Navigation -->
<button id="previous" onclick="previous()">Previous</button>
<button id="next" onclick="next()">Next</button>
<!-- Jump to -->
<label for="month">Jump To: </label>
<select name="month" id="month" onchange="jump()">
  <option value=0>Jan</option>
  <option value=1>Feb</option>
  <option value=2>Mar</option>
  <option value=3>Apr</option>
  <option value=4>May</option>
  <option value=5>Jun</option>
  <option value=6>Jul</option>
  <option value=7>Aug</option>
  <option value=8>Sep</option>
  <option value=9>Oct</option>
  <option value=10>Nov</option>
  <option value=11>Dec</option>
</select>

<select name="year" id="year" onchange="jump()">

2. Load the main script at the end of the document. That’s it.

<script src="scripts.js"></script>
