In modern web development, integrating a real-time digital clock using jQuery enhances user experience and interactivity. Whether used in dashboards, admin panels, e-commerce sites, or personal blogs, a jQuery-powered clock provides a live timekeeping feature that updates dynamically without needing a page refresh.
By using jQuery, we can manipulate the DOM efficiently, ensuring smooth updates without excessive resource consumption. The core advantage of using jQuery in such applications is its lightweight syntax, cross-browser compatibility, and powerful selectors. These features make it easier to update HTML elements dynamically with minimal code. Additionally, jQuery simplifies working with event handling, AJAX calls, and animations, making it a preferred choice for dynamic UI components.
In this tutorial, we will create a stylish digital clock using HTML, CSS, and jQuery. The design includes a small left box displaying the current date (format: 1st Jan 2025) and a right box showing the live digital time (format: hr:min:sec AM/PM). We will walk through the entire coding process to ensure you can implement this feature seamlessly into your website.
To begin, we create a simple HTML layout that will serve as the base structure for our clock.
<!DOCTYPE html>
<html lang="en">

<body>
<div class="clock-container">
<div class="date-box" id="date">1st Jan 2025</div>
<div class="time-box" id="time">12:00:00 AM</div>
</div>
</body>
</html>To create an elegant and readable design, we use CSS for styling.
/* styles.css */
body {
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
background: #222;
color: white;
font-family: Arial, sans-serif;
}
.clock-container {
display: flex;
gap: 20px;
background: #333;
padding: 20px;
border-radius: 10px;
box-shadow: 0px 0px 10px rgba(0, 0, 0, 0.5);
}
.date-box, .time-box {
padding: 10px 20px;
background: #444;
border-radius: 5px;
font-size: 20px;
}Now, let's write the jQuery script to update the clock dynamically.
// script.js
$(document).ready(function () {
function updateClock() {
let now = new Date();
// Format Date
let day = now.getDate();
let monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
let month = monthNames[now.getMonth()];
let year = now.getFullYear();
let suffix = (day % 10 === 1 && day !== 11) ? "st" : (day % 10 === 2 && day !== 12) ? "nd" : (day % 10 === 3 && day !== 13) ? "rd" : "th";
let formattedDate = `${day}${suffix} ${month} ${year}`;
$("#date").text(formattedDate);
// Format Time
let hours = now.getHours();
let minutes = now.getMinutes();
let seconds = now.getSeconds();
let ampm = hours >= 12 ? "PM" : "AM";
hours = hours % 12 || 12;
minutes = minutes < 10 ? "0" + minutes : minutes;
seconds = seconds < 10 ? "0" + seconds : seconds;
let formattedTime = `${hours}:${minutes}:${seconds} ${ampm}`;
$("#time").text(formattedTime);
}
setInterval(updateClock, 1000);
updateClock(); // Initial call to display clock immediately
});By using jQuery selectors and functions, we efficiently manipulate the DOM without refreshing the page, ensuring seamless user experience.
By implementing this real-time digital clock, you’ve learned how to:
This interactive feature can be integrated into dashboard panels, booking systems, e-commerce stores, and news portals to enhance real-time user engagement. Experiment with different CSS styles, animations, and formats to match your website’s theme.
With jQuery’s simplicity and efficiency, you can further expand this functionality by adding time zones, event countdowns, or alarm features in future projects.
