How do I calculate how many seconds between two dates?
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);
A handy source for future reference is the MDN site
Alternatively, if your dates come in a format javascript can parse
var dif = Date.parse(MM + " " + DD + ", " + YYYY) - Date.parse(NN + " " + EE + ", " + ZZZZ);
and then you can use that value as the difference in milliseconds (dif in both my examples has the same meaning)
Just subtract:
var a = new Date();alert("Wait a few seconds, then click OK");var b = new Date();var difference = (b - a) / 1000;console.log("You waited: " + difference + " seconds");
You can do it simply.
var secondBetweenTwoDate = Math.abs((new Date().getTime() - oldDate.getTime()) / 1000);
