date format from the backend. My goal is to determine how many days ago it was.
For example, today is the 20th, so if the date is today's date, it should show as 0 days ago.

Feel free to test out this snippet of code.
let startDate = new Date("01/01/2022");
let endDate = new Date("01/10/2022");
let daysDifference = parseInt((endDate - startDate) / (1000 * 60 * 60 * 24), 10);
console.log(daysDifference)If you want to compare two dates, you can subtract them to find the difference in milliseconds, which can then be converted into days.
const currentDate = new Date();
// Simulating a past date
const daysAgoDate = new Date();
daysAgoDate.setDate(daysAgoDate.getDate() - 10);
// Calculate the difference between the two dates in milliseconds
const timeDifferenceMs = currentDate - daysAgoDate;
// Convert the milliseconds to days
const daysDifference = Math.round(timeDifferenceMs / (1000 * 60 * 60 * 24));
console.log(daysDifference)Calculate the number of days since December 10, 2019 at 14:07:21 by subtracting the current date from that date and converting the result to days.
When you're attempting to find the difference in days between two dates, it's referred to as "date diff". To achieve this, you must first create a new Date object from the string representing the dates. One way to do this is by utilizing the Moment.js library, which can parse the date string and return a Date object.
var date1 = moment("10 Dec, 2019T14:07:21", "DD MMM, YYYY");
var date2 = new Date() //today date
A handy JavaScript function for calculating the date difference is provided below:
function dateDiff(date1, date2) {
var datediff = date1.getTime() - date2.getTime();
return (datediff / (24*60*60*1000));
}
The dateDiff function will give you the difference between the dates; if date1 is in the past, it will return a negative number of days. To display the result in the format like "x days ago," simply multiply the result by -1.
