So to calculate the remaining time in hours, we will divide the remainder by 1000 * 60 * 60 (1 hour in milliseconds). Step 7: Next, we will use modulo operator on timeDifference value by 1000 * 60 * 60 * 24 to get the remaining hours time in Milliseconds. Step 6: We will divide the timeDifference value by 1000 * 60 * 60 * 24 (1 day time in milliseconds). timeDifference = countDownDate - currentTime Step 5: We will store the current time in a variable currentTime and then calculate the time difference by using subtraction operation. After that, we call a function that will be executed till 1 second. Step 4: In JavaScript, first we will store the end date in a variable countDownDate. Step 3: Now, we will add some CSS styles on the main div, sub divs and span elements to make it attractive. Step 2: After the main div, we have created one more div that display some content when event ended. The tag display the remaining time, and tag display the days, hours, minutes, and seconds in the respective place. The sub div element contains two elements, and. Step 1: We will create a main div with id countDownTimer that contains four sub div’s that will display the Countdown remaining time in days, hours, minutes, and seconds. After that, we will use JavaScript to add the functionality feature of Countdown timer. First, we will create a basic Skelton to Countdown timer using HTML, and apply CSS styles to make it attractive and user-friendly. We will use HTML, CSS, and JavaScript to create a countdown timer.
