Basic JavaScript countdown timer example:
// Set the target date
const targetDate = new Date("Dec 31, 2025 23:59:59").getTime();
// Update every second
const timer = setInterval(function() {
const now = new Date().getTime();
const distance = targetDate - now;
// Calculate time units
const days = Math.floor(distance / (1000 * 60 * 60 * 24));
const hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
const minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
const seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Display result
document.getElementById("timer").innerHTML =
days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
// When countdown ends
if (distance < 0) {
clearInterval(timer);
document.getElementById("timer").innerHTML = "EXPIRED";
}
