Javascript Invalid Date Error in Internet Explorer

Question

Relatively simple javascript here, not sure why IE hates me (treat others how you want to be treated I suppose).

var newDate = new Date("2012, 11, 2 19:30:00:000");
alert(newDate);

This works in Chrome and FF, but IE outputs "Invalid Date"

Fiddle me this: http://jsfiddle.net/k6yD6/

I actually get invalid date in Firefox as well (latest version, 16.0.1). – Campanula

Just make sure you're using a properly supported format. This question has been asked plenty of times before, #3021008 – Hula

for IE its dateObj = new Date(year, month, date[, hours[, minutes[, seconds[,ms]]]]) – Alveta

Don't worry. IE hates everyone – Cilla

Or Microsoft could just BE NICE like other browsers! .. Terrible browser – Pup

Answer 1

The string given to the date constructor should be an RFC2822 or ISO 8601 formatted date. In your example it isn't. Try the following:

new Date("2012-11-02T19:30:00.000Z");

or using an alternate constructor:

new Date(2012, 11, 2, 19, 30, 0)

thanks, the alternate constructor works however the first one you listed doesn't seem to in any browser – Repro

@DougieBear Answer updated - I had missed a required zero before the day – Pacific

new Date("2012-11-02T19:30:00.000Z"); The milliseconds can be ommitted, but if included must be preceded by a dot, not a colon. – Soliloquy

I had to split my date string and add a T & Z !! – Slacken

Answer 2

IE does not seem to support millisecond and months in Numerical String. Try this:

new Date("November 2, 2012 19:30:00");

or

new Date(year, month, day, hours, minutes, seconds, milliseconds)

new Date("November 2, 2012 19:30:00"); - This saved me a lot of pain. – Ladd

Answer 3

I was having the same issue with Internet Explorer. This is how I was formatting the date and time initially,

function formatDateTime(date, formatString = 'MM/DD/YYYY hh:mm A') {
  return moment(new Date(date)).format(formatString);
}

The problem was with new Date(). I just removed it as it was already a UTC date. So it is just,

return moment(date).format(formatString);

This worked for me in all browsers including IE.

OP does not mention using moment.js library. – Mode

Other people besides OP view this page looking for answers, and some of them are using moment.js – Vasily

Answer 4

Use

var newDate = moment("2012, 11, 2 19:30:00:000").toDate();
alert(newDate);

This will work in IE too.

Answer 5

To work in IE, date should be in proper format. I fixed this same issue by using below format:

var tDate = new Date('2011'+"-"+'01'+"-"+'01'); //Year-Month-day

When I passed this year-month-day format into my code, it fixed the problem... gotta give you a 1 up. However, I didn't need the new Date, just change the format as a string and the date appeared correctly on the server side via IE 11. – Spreadeagle

Answer 6

var time = new Date("2021-12-01 17:02:12");
if(isNaN(time))
{
    time= new Date(date.replace(/ /g,'T')+'.000Z');
}
