Question: Facing a problem with `JavaScript Date` function, `returns "Date {Invalid Date}"` in Firefox browser but works fine in Google chrome.

```
// My Input is
new Date("Sat Jan 01 00:00:00 EST 1");

// Works fine in google chrome 
// Result: Mon Jan 01 2001 10:30:00 GMT+0530 (India Standard Time)

// Not working in Firefox (Version: 15.0.1)
// Result: Date {Invalid Date}

```

Answer: 
[Date](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date) does not take a timezone parameter in that way. My thought is that Chrome is just ignoring it. 

```
new Date(year, month, day [, hour, minute, second, millisecond])

```

Please see @Brett's comment below for more information.
Make sure the parameter is RFC1123 compliant: <https://www.rfc-editor.org/rfc/rfc1123>
