Reset localstorage variable at specific time

How do I reset a localStorage variable that is a boolean that tracks whether a user has completed an action that day. When the time reaches, for example, 8 am local time, it resets the boolean to false to show that the action hasn’t been completed yet.

If the user has completed the action that day, the localStorage variable gets set to true and we show the countdown to 8 am.

Here are my methods that check for current time and time until 8 am.

const twoDigits = (number) => {
    return (number < 10 ? '0' : '') + number;
}

const countDown = () => {
    var reset = new Date();
    var now = new Date();
    reset.setHours(8, 0, 0);
    if(now > reset){
        reset.setDate(reset.getDate() + 1);
    }

    var timeToReset = ((reset - now) / 1000);

    var hours = ~~(timeToReset / 60 / 60) % 60;
    var minutes = ~~(timeToReset / 60) % 60;
    var seconds = ~~timeToReset % 60;

    return `${twoDigits(hours)}:${twoDigits(minutes)}:${twoDigits(seconds)}`;
}

const intervalId = setInterval(() => {
  console.log(countDown());
}, 1000);

// clear interval after 10 seconds so its not running indefinitely
setTimeout(() => {clearInterval(intervalId)}, 10000);
