Luxon/JavaScript get round days difference compare with day strings and today's Date

Question

I'm just getting started with luxon and JavaScript's 'Date'. I use the following date format: Sat Feb 05 2022 00:00:00 GMT+0200 (Eastern European Standard Time) . I want to compare the dates with today's date and get the days difference from this format Sat Feb 05 2022 00:00:00 GMT+0200 (Eastern European Standard Time) . However, I am receiving decimal days '2.5154091898148145' when my expected output is two days. I don't how to fix it.

Also I want to get next dates and previous dates.

Thank you in advanced.

 const { DateTime } = require("luxon"); const today = new Date(); const day = "Sat Feb 05 2022 00:00:00 GMT+0200 (Eastern European Standard Time)"; const date1 = DateTime.fromISO(new Date(day).toISOString()); const diff = date1.diff(DateTime.now(), ["days"]).toObject(); console.log(diff.days); // Output // 2.520294085648148 // Expected output // 1. Compare day should be 2 days // 2. Find next day('2022-02-06') and previous day(('2022-02-04')) from `day` variable // 3. Return date format like this: 5.2.2022 from `day` variable

You can just use Math.round() or Math.floor() on the result as needed:

const { DateTime } = require("luxon");

const today = new Date();
const day =
  "Sat Feb 05 2022 00:00:00 GMT+0200 (Eastern European Standard Time)";

const date = DateTime.fromISO(new Date(day).toISOString());
const diff = date.diff(DateTime.now(), ["days"]).toObject();
const days = Math.floor(diff.days)

console.log(days); //2
