How to get day difference between two dates in javascript?

Question

Say I have two dates: 1/24/2020 11:55:00 PM and 1/25/2020 01:00:00 AM. Real difference between them is about 2 hours but the day has changed. I want the difference in days which would be 1.

I have tried https://stackoverflow.com/a/52054494/6288172 but it doesn't give me the right answer.

@FábioBCSouza it doesn't work. A difference of 2 hours would give me day difference smaller than 0.5 which would mean same day. But in my example above, even though its only 2 hours but the day has changed so the answer should be 1. — ParmuTownley, Jan 25 '20 at 04:08
Since you're interested in only days, you can set both dates to the same hour, minutes and seconds and use that solution. — Titus, Jan 25 '20 at 04:10

// your code goes here
var time = new Date(2020,0,25,23,23,23,2);
var date = new Date(time.toDateString()); // Sat Jan 25 2020 00:00:00 GMT+0000 (UTC)

var time1 = new Date(2020,0,26,2,2,2,2);
var date1 = new Date(time1.toDateString()); // Sun Jan 26 2020 00:00:00 GMT+0000 (UTC)

var diff = Math.round(Math.abs((date - date1)/(1000 * 60 * 60 * 24)));

console.log(diff); //1
