Write a JavaScript function to get time differences in hours between two dates. Test Data: dt1 = new Date("October 13, 2014 08:11:00"); dt2 = new Date("October 13, 2014 11:13:00"); console.log(diff_hours(dt1, dt2)); 3
return time1.getTime() - time2.getTime(); } // const timeComparison = (time1, time2) => time1.getTime() - time2.getTime(); /** * calculateNumberOfDaysBetweenTwoDates() * 计算两个日期之间相隔天数 * * @param time1 * @param time2 * @return {number} 时间差(天数) */ f...

Unfortunately, calculating a date interval such as days, weeks, or months between two known dates is not as easy because you can’t just add Date objects together. In order to use a Date object in any sort of calculation, we must first retrieve the Date’s internal millisecond value, whic...
There is a simpler code that we will give, but this one provides access to more information about the dates.For example, the age of the Eiffel Tower is 136 years, a number that is calculated using the following formula: new Number((new Date().getTime() - new Date("31 March 1889")...
计算两个日期之间的差值,可以使用getTime()方法: letdate1=newDate("2023-10-12");letdate2=newDate("2023-10-20");letdifference=date2.getTime()-date1.getTime();letdaysDifference=difference/(1000*3600*24);// 转换为天数console.log(`两个日期之间相差${daysDifference}天`); ...
