如何计算两个日期之间的间隔秒数? [英] How do I calculate how many seconds between two dates?

问题描述

所以我有两个日期 YYYY-MM-DD 和 ZZZZ-NN-EE

我如何找出它们之间有多少秒?

How can I find out how many seconds there are between them?

推荐答案

我正在使用YYYY&ZZZZ表示整数值，表示年份MM&NN表示整数值，表示一年中的月份以及DD&EE为整数值，表示每月的某天.

I'm taking YYYY & ZZZZ to mean integer values which mean the year, MM & NN to mean integer values meaning the month of the year and DD & EE as integer values meaning the day of the month.

var t1 = new Date(YYYY, MM, DD, 0, 0, 0, 0);
var t2 = new Date(ZZZZ, NN, EE, 0, 0, 0, 0);
var dif = t1.getTime() - t2.getTime();

var Seconds_from_T1_to_T2 = dif / 1000;
var Seconds_Between_Dates = Math.abs(Seconds_from_T1_to_T2);

MDN网站是方便参考的资源

或者，如果您的日期采用javascript可以解析的格式

Alternatively, if your dates come in a format javascript can parse

var dif = Date.parse(MM + " " + DD + ", " + YYYY) - Date.parse(NN + " " + EE + ", " + ZZZZ);

然后您可以将该值用作毫秒之间的差异(在我的两个示例中，dif的含义相同)

and then you can use that value as the difference in milliseconds (dif in both my examples has the same meaning)
