Suppose to have a future timestamp date.
var timestamp="1511858535000" //Future timestamp
var date=new Date(timestamp);
console.log(JSON.stringify(date));// this line give me Invalid Data
Anyone can help me to understand why?

The timestamp you mentioned in the comments works fine, but you have to pass it into the Date constructor as a number, not a string:
var timestamp = "1511858535000";
var date = new Date(Number(timestamp));
console.log(JSON.stringify(date));

Add A Year To Today's Date

I want to get the timestamp of one-year from now:
var oneYr = new Date();
oneYr.setYear((new Date()).getYear() + 1);
When I try to get the timestamp:
oneYr.getTime() /1000
I get -58351759111000 (not correct)
It's only working for date in the past.
Any idea how to get timestamp for future date?
Use getFullYear instead of getYear.
var oneYr = new Date();
oneYr.setYear((new Date()).getFullYear() + 1);

How can i get first and last day of current week in ISO Date format in javascript? [duplicate]

$gte: ISODate("2010-04-29T00:00:00.000Z"),$lt: ISODate("2010-05-01T00:00:00.000Z")
You may get the day of the week by calling .getDay() on the date object. Once you have the day of the week, rest are arithmetic operations.
To convert Date to ISODateFormat you can use toISOString
var dateForCalculation = new Date();
var prevSunday = new Date(dateForCalculation.setDate(dateForCalculation.getDate()-dateForCalculation.getDay())).toISOString();
var nextSunday = new Date(dateForCalculation.setDate(dateForCalculation.getDate()+7)).toISOString();
console.log(prevSunday);
console.log(nextSunday);

JSFiddle: https://jsfiddle.net/u8w3v9fd/1/
I am trying to get the day, month and year from a date that is passed form the database in the format: DD/MM/YYYY. However I can't even seem to get the correct date to show.
Here is my code:
var time = "1522843537";
var regDateOriginal = new Date(time);
var regDate = new Date();
regDate.getMonth(regDateOriginal);
regDate.getHours(regDateOriginal);
regDate.getDate(regDateOriginal);
document.write("<p style='color: #fff'>" + regDate.getDate(regDateOriginal) + "</p>");
As you can see, this is returning:
21
Which is todays date. It should be 4
I have googled it and hacked around with various versions for the past 45 mins. I am a junior and would really appreciated a nicely commented piece of code so I can learn instead of just copying and pasting.
Thank you for your help.
From here
var time = 1522843537;
var d = new Date(0); // The 0 there is the key, which sets the date to the epoch
d.setUTCSeconds(time);
console.log(d.getDate());
Of course, you can still do all the other Date functions as needed.

There is something like that, called setDate().

date.setDate(date.getDate() + 1);
console.log(date);

getDate(); // 0-31, 1-based day of month,
