JSON.stringify returns wrong value for the Date Object

Question

the below code returns one day earlier,

var myJSON = JSON.stringify(new Date("02/02/1997"));
alert(myJSON);

myJSON variables returns "1997-02-01T18:30:00.000Z"

Why its returning wrong value.

Here, what does the meaning of "T18:30:00.000Z"

Is there any other way of converts the Date object to the String.

what you're trying to achieve, your original data seems to be a string "02/02/1997"? — cur4so, Feb 13 '17 at 04:54
It's not the wrong date. If your timezone offset is +05:30 it's the correct date and transferable to any other system.

Try this..

    var myJSON = JSON.stringify(new Date("02/02/1997").toLocaleString());
    alert(myJSON);

Even if parsing the string produces the correct date (which is problematic), the result of *toLocaleString* is entirely implementation dependent and the string produced by one host may not be parsed correctly by another. – RobG Feb 13 '17 at 09:37

It is converting your Date object to UTC date.

You should convert Date object to String value using predefined methods of Date Object. Like:

JSON.stringify(new Date("02/02/1997").toLocaleString());

JSON.stringify(new Date("02/02/1997").toDateString()); // to get date portion

No, don't do that. Parsing a string like "02/02/1997" is not a good idea. Also, the result of *toLocaleString* is entirely implementation dependent and the string created by one host may not be parseable by another. – RobG Feb 13 '17 at 09:36

Recommend you take a look at moment.js. The framework provides a very nice API for:

Parse, validate, manipulate, and display dates in JavaScript.

Convert your date into the desired string format and then JSON.stringify.

I don't think suggesting a library is appropriate for answering a question about JavaScript's standard library – PaulBGD Feb 13 '17 at 05:00

Given the endless fun of JavaScript date handling thought I'd drop it in to the conversation. Sorry for the static. – Ben Crowhurst Feb 13 '17 at 05:01
I totally agree that moment.js is great, it's just not something that's relevant as to how JavaScript's standard library works. – PaulBGD Feb 13 '17 at 05:02
