Error when I refresh count down it's restart

I have this code for CountDown and When I refresh the page It's count from the beginning.
I want to continue counting from where it arrived even after several times of the update:

Save the countdown in sessionStorage, and start from there when the page is reloaded.

Why don't you set deadline to the actual time instead of always adding 15 days to the current time?

Save the countdown in sessionStorage, and start from there when the page is reloaded.

Why don't you set deadline to the actual time instead of always adding 15 days to the current time?

Save the countdown in sessionStorage, and start from there when the page is reloaded.

Save deadline in sessionStorage.

Replace the two lines:

var deadline = new Date(Date.parse(new Date()) + 15 * 24 * 60 * 60 * 1000);

initializeClock('clockdiv', deadline);

with this:

var deadline;

var savedDeadline = sessionStorage.getItem("deadline");

if (savedDeadline) {

    deadline = parseInt(savedDeadline);

} else {

    deadline = new Date(Date.parse(new Date()) + 15 * 24 * 60 * 60 * 1000);

    sessionStorage.setItem("deadline", deadline);

}

initializeClock('clockdiv', deadline);

I'm not going to rewrite the whole thing when I'm just replacing two lines. I've updated the answer to explain exactly how this fits in.

I included a link to the sessionStorage documentation. If that's not enough, I'm sure you can find tutorials using Google.
