Countdown Example Development Tutorials, Guides & Insights

We need a function that takes the end time (the deadline) as input and calculates the difference between the current time and the deadline:

function getTimeRemaining(endtime) {
    const total = Date.parse(endtime) - Date.now();
    const seconds = Math.floor((total / 1000) % 60);
    const minutes = Math.floor((total / 1000 / 60) % 60);
    const hours = Math.floor((total / (1000 * 60 * 60)) % 24);
    const days = Math.floor(total / (1000 * 60 * 60 * 24));

    return {
        total,
        days,
        hours,
        minutes,
        seconds
    };
}
