![]() ![]() We may notice the times we have the countdown for new year’s Day so that we will use the upcoming new year as our end-time calculation for the countdown time. We all know to calculate the remaining time with the help of the current actual time and the time that goes to the countdown for it will expire. The timer saves and can serve many purposes because it can communicate to the user how much it would be extended if they have been doing something or how much time they save until some event happens, like the launch of a new website. We can also stop the scripts for executing the functions using the clearInterval method. It measures and clears the values for days, hours, minutes, and seconds and displays the heading when the timer is up. Once we used countdown options in the script, it took appropriate actions for the countdown time will end. Once we can calculate the date differences next step, we can calculate the time as milliseconds format into days, hours, minutes, and seconds. We can calculate the time differences in milliseconds between the current and the end dates. The JavaScript function will be used for utilizing and creating the var datatypes, and it makes it run for every time second using the setInterval() method to set the time intervals. The getTime() method makes the countDownDate variables hold the milliseconds since the date is started, like Jan 1,0000,00:00.000 GMT. Mainly we will focus on creating the Date Object, and then we call the method like getTime() to use on this instance. We have to declare the variables first and that it holds the date and time objects also, we want our countdown timers to run down it. ![]() The javascript countdown timer will create the timer settings for the user’s perspective. We have used the method called Math.floor() method for calculating the above scenarios using the formulas. We must create the date instance and manually set the time interval for hours, minutes, and seconds format for each requirement. we can write the codes like date,time calculation for both hours,minutes and seconds even though we also calculate the milliseconds they have the some default formulas for getting the above requirement. Whenever we need the countdown feature, we will use the date() instance for getting the time intervals in either type.
