Question

JavaScript

Hi all! Help me please! I need to calculate the total time and display the result in hours as a number ( Should be 80 hours ). We need endDate to subtract startDate and get the result like this: result = 80;

var startDate = "2020-09-04T11:38:22.283Z";
    var endDate = "2020-09-18T11:38:00.000Z";

Answer 1

(new Date(endDate).getTime() - new Date(startDate).getTime()) / 1000 / 60 / 60
