![]() Then use modulus operator (%) and take modulus at 60 to get minutes in range 0-60. Now, this is in minutes but has fractional value. To convert milliseconds to minutes divide it by 1000 * 60. const time = 450524354 // random timeĬonst seconds = Math.floor(time / 1000) % 60 Ĭonsole.log(seconds) Convert milliseconds to minutes Then use modulus operator (%) and take modulus at 60 to get seconds in range 0-60. Use Math.floor to convert it to an integer. Now, this is second but has fractional value. To convert milliseconds to seconds divide it by 1000. The following example takes 450524354 milliseconds and calculates days, hours, minutes and seconds. While creating countdown time you will have to calculate remaining days, hours, minutes and seconds to display it on screen.Īll this information will be deduced from a number of remaining milliseconds to the event. const date1 = new Date('15:23:00') Ĭonst difference = date1.getTime() - date2.getTime() Ĭonsole.log(difference) // 339251555000 Calculate the remaining time Using above method we can find time elapsed for 2 different time and can take difference moment of time. const date = new Date('02:50:25') Ĭonsole.log(milliseconds) // 946675225000 Calculate difference between 2 moment of time Now we know how to get time elapsed since default date (january 1, 1970) but you can also pass a date and time in form of string to get time spend since some exact date and time. We need this because we will use this to find difference between 2 different moments of time to get time remaining to some event (birthday). Now let's see how to get milliseconds elapsed since a date and time. The following code show how to create a new Date object that represents the current date and time: const now = new Date() The Date object is specified as the number of milliseconds that have passed since midnight on January 1, 1970, UTC. ![]() It represents a single moment in the time. To create time you will need to work with Date object. The last element is a paragraph element with class name 'coming-year', which will be used to show coming birthday year in the background.īefore we go through javascript code let us first understand a few javascript logic that will be used further in the section.The listing items contain tag with a different class name which will be used to select the element using javascript and put the timer. The second element is a list element where you list remaining days, remaining hours, remaining minutes and remaining seconds to the timer.The first element in element with class 'countdown-timer' is the heading of the app which greets the user and state purpose.The body tag in the above code contains an element with class 'countdown-timer' which holds all elements of the app. Let's first see the complete HTML code for the countdown timer app. The HTML code contains a element with class name 'countdown', it holds everything about the timer app. In head section it connects to the style.css using tag and in body section it connects to script.js file using tag. The HTML code for the countdown timer is quite simple. You create project folder will look like this: Creating HTML for countdown ![]() Second, download birthday celebration image to this project folder which will be used for the background of the birthday countdown.
