Invalid date in safari
JavascriptDateSafariJavascript Problem Overview
alert(new Date('2010-11-29'));
chrome, ff doesn't have problems with this, but safari cries "invalid date". Why ?
edit : ok, as per the comments below, I used string parsing and tried this :
alert(new Date('11-29-2010')); //doesn't work in safari
alert(new Date('29-11-2010')); //doesn't work in safari
alert(new Date('2010-29-11')); //doesn't work in safari
edit Mar 22 2018 : Seems like people are still landing here - Today, I would use moment
or date-fns
and be done with it. Date-fns is very much pain free and light as well.
Javascript Solutions
Solution 1 - Javascript
For me implementing a new library just because Safari cannot do it correctly is too much and a regex is overkill. Here is the oneliner:
console.log (new Date('2011-04-12'.replace(/-/g, "/")));
Solution 2 - Javascript
The pattern yyyy-MM-dd
isn't an officially supported format for Date
constructor. Firefox seems to support it, but don't count on other browsers doing the same.
Here are some supported strings:
- MM-dd-yyyy
- yyyy/MM/dd
- MM/dd/yyyy
- MMMM dd, yyyy
- MMM dd, yyyy
DateJS seems like a good library for parsing non standard date formats.
Edit: just checked ECMA-262 standard. Quoting from section 15.9.1.15:
Date Time String Format
> ECMAScript defines a string > interchange format for date-times > based upon a simplification of the ISO > 8601 Extended Format. The format is > as follows: YYYY-MM-DDTHH:mm:ss.sssZ > Where the fields are as follows: > > - YYYY is the decimal digits of the year in the Gregorian calendar. > - "-" (hyphon) appears literally twice in the string. > - MM is the month of the year from 01 (January) to 12 (December). > - DD is the day of the month from 01 to 31. > - "T" appears literally in the string, to indicate the beginning of > the time element. > - HH is the number of complete hours that have passed since midnight as two > decimal digits. > - ":" (colon) appears literally twice in the string. > - mm is the number of complete minutes since the start of the hour as > two decimal digits. > - ss is the number of complete seconds since the start of the minute > as two decimal digits. > - "." (dot) appears literally in the string. > - sss is the number of complete milliseconds since the start of the > second as three decimal digits. Both > the "." and the milliseconds field may > be omitted. > - Z is the time zone offset specified as "Z" (for UTC) or either "+" or "-" > followed by a time expression hh:mm > > This format includes date-only forms: > > - YYYY > - YYYY-MM > - YYYY-MM-DD

So, it seems that YYYY-MM-DD is included in the standard, but for some reason, Safari doesn't support it.
Update: after looking at datejs documentation, using it, your problem should be solved using code like this:
var myDate1 = Date.parseExact("29-11-2010", "dd-MM-yyyy");
var myDate2 = Date.parseExact("11-29-2010", "MM-dd-yyyy");
var myDate3 = Date.parseExact("2010-11-29", "yyyy-MM-dd");
var myDate4 = Date.parseExact("2010-29-11", "yyyy-dd-MM");
Solution 3 - Javascript
I was facing a similar issue. Date.Parse("DATESTRING")
was working on Chrome (Version 59.0.3071.115 ) but not of Safari (Version 10.1.1 (11603.2.5) )
Safari:
Date.parse("2017-01-22 11:57:00")
NaN
Chrome:
Date.parse("2017-01-22 11:57:00")
1485115020000
The solution that worked for me was replacing the space in the dateString with "T"
. ( example : dateString.replace(/ /g,"T")
)
Safari:
Date.parse("2017-01-22T11:57:00")
1485086220000
Chrome:
Date.parse("2017-01-22T11:57:00")
1485115020000
Note that the response from Safari browser is 8hrs (28800000ms) less than the response seen in Chrome browser because Safari returned the response in local TZ (which is 8hrs behind UTC)
To get both the times in same TZ
Safari:
Date.parse("2017-01-22T11:57:00Z")
1485086220000
Chrome:
Date.parse("2017-01-22T11:57:00Z")
1485086220000
Solution 4 - Javascript
I use moment to solve the problem. For example
var startDate = moment('2015-07-06 08:00', 'YYYY-MM-DD HH:mm').toDate();
Solution 5 - Javascript
To have a solution working on most browsers, you should create your date-object with this format
(year, month, date, hours, minutes, seconds, ms)
e.g.:
dateObj = new Date(2014, 6, 25); //UTC time / Months are mapped from 0 to 11
alert(dateObj.getTime()); //gives back timestamp in ms
works fine with IE, FF, Chrome and Safari. Even older versions.
Solution 6 - Javascript
convert string to Date fromat (you have to know server timezone)
new Date('2015-06-16 11:00:00'.replace(/\s+/g, 'T').concat('.000+08:00')).getTime()
where +08:00 = timeZone from server
Solution 7 - Javascript
I had the same issue.Then I used moment.Js.Problem has vanished.
> When creating a moment from a string, we first check if the string > matches known ISO 8601 formats, then fall back to new Date(string) if > a known format is not found. > > Warning: Browser support for parsing strings is inconsistent. Because > there is no specification on which formats should be supported, what > works in some browsers will not work in other browsers. > > For consistent results parsing anything other than ISO 8601 strings, > you should use String + Format.
e.g.
var date= moment(String);
Solution 8 - Javascript
Though you might hope that browsers would support ISO 8601 (or date-only subsets thereof), this is not the case. All browsers that I know of (at least in the US/English locales I use) are able to parse the horrible US MM/DD/YYYY
format.
If you already have the parts of the date, you might instead want to try using Date.UTC(). If you don't, but you must use the YYYY-MM-DD
format, I suggest using a regular expression to parse the pieces you know and then pass them to Date.UTC()
.
Solution 9 - Javascript
How about hijack Date
with fix-date? No dependencies, min + gzip = 280 B
Solution 10 - Javascript
I am also facing the same problem in Safari Browser
var date = new Date("2011-02-07");
console.log(date) // IE you get ‘NaN’ returned and in Safari you get ‘Invalid Date’
Here the solution:
var d = new Date(2011, 01, 07); // yyyy, mm-1, dd
var d = new Date(2011, 01, 07, 11, 05, 00); // yyyy, mm-1, dd, hh, mm, ss
var d = new Date("02/07/2011"); // "mm/dd/yyyy"
var d = new Date("02/07/2011 11:05:00"); // "mm/dd/yyyy hh:mm:ss"
var d = new Date(1297076700000); // milliseconds
var d = new Date("Mon Feb 07 2011 11:05:00 GMT"); // ""Day Mon dd yyyy hh:mm:ss GMT/UTC
Solution 11 - Javascript
For people using date-fns
we can parseISO
date and use it to format
Invalid
import _format from 'date-fns/format';
export function formatDate(date: string, format: string): string {
return _format(new Date(date), format);
}
This function on safari throw error with Invalid date
.
Solution
To fix it we should use:
import _format from 'date-fns/format';
import _parseISO from 'date-fns/parseISO';
export function formatDate(date: string, format: string): string {
return _format(_parseISO(date), format);
}
Solution 12 - Javascript
Use the below format, it would work on all the browsers
var year = 2016;
var month = 02; // month varies from 0-11 (Jan-Dec)
var day = 23;
month = month<10?"0"+month:month; // to ensure YYYY-MM-DD format
day = day<10?"0"+day:day;
dateObj = new Date(year+"-"+month+"-"+day);
alert(dateObj);
//Your output would look like this "Wed Mar 23 2016 00:00:00 GMT+0530 (IST)"
//Note this would be in the current timezone in this case denoted by IST, to convert to UTC timezone you can include
alert(dateObj.toUTCSting);
//Your output now would like this "Tue, 22 Mar 2016 18:30:00 GMT"
Note that now the dateObj shows the time in GMT format, also note that the date and time have been changed correspondingly.
The "toUTCSting" function retrieves the corresponding time at the Greenwich meridian. This it accomplishes by establishing the time difference between your current timezone to the Greenwich Meridian timezone.
In the above case the time before conversion was 00:00 hours and minutes on the 23rd of March in the year 2016. And after conversion from GMT+0530 (IST) hours to GMT (it basically subtracts 5.30 hours from the given timestamp in this case) the time reflects 18.30 hours on the 22nd of March in the year 2016 (exactly 5.30 hours behind the first time).
Further to convert any date object to timestamp you can use
alert(dateObj.getTime());
//output would look something similar to this "1458671400000"
This would give you the unique timestamp of the time
Solution 13 - Javascript
Best way to do it is by using the following format:
new Date(year, month, day, hours, minutes, seconds, milliseconds)
var d = new Date(2018, 11, 24, 10, 33, 30, 0);
This is supported in all browsers and will not give you any issues. Please note that the months are written from 0 to 11.
Solution 14 - Javascript
For me the issue was I forgot to add 0
before the single digit month or day in YYYY-MM-DD
format.
What I was parsing: 2021-11-5
What it should be: 2021-11-05
So, I wrote a little utility which converts YYYY-M-D
to YYYY-MM-DD
i.e. 2021-1-1
to 2021-01-01
:
const date = "2021-1-1"
const YYYY = date.split("-")[0];
//convert M->MM i.e. 2->02
const MM =
date.split("-")[1].length == 1
? "0" + date.split("-")[1]
: date.split("-")[1];
//convert D->DD i.e. 2->02
const DD =
date.split("-")[2].length == 1
? "0" + date.split("-")[2]
: date.split("-")[2];
// YYYY-MM-DD
const properDateString = `${YYYY + "-" + MM + "-" + DD}`;
const dateObj = new Date(properDateString);

As @nizantz previously mentioned, using Date.parse() wasn't working for me in Safari. After a bit of research, I learned that the lastDateModified property for the File object has been deprecated, and is no longer supported by Safari. Using the lastModified property of the File object resolved my issues. Sure dislike it when bad info is found online.
Thanks to all who contributed to this post that assisted me in going down the path I needed to learn about my issue. Had it not been for this info, I never would have probably figured out my root issue. Maybe this will help someone else in my similar situation.
Solution 16 - Javascript
Arriving late to the party but in our case we were getting this issue in Safari & iOS when using ES6 back tick instead of String() to type cast
This was giving 'invalid date' error
const dateString = '2011-11-18';
const dateObj = new Date(`${dateString}`);
But this works
const dateObj = new Date(String(dateString));
Solution 17 - Javascript
The same problem facing in Safari and it was solved by inserting this in web page
<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=Intl.~locale.en"></script>
Hope it will work also your case too
Thanks
Solution 18 - Javascript
This will not work alert(new Date('2010-11-29'));
safari have some weird/strict way of processing date format alert(new Date(String('2010-11-29')));
try like this.
(Or)
Using Moment js will solve the issue though, After ios 14 the safari gets even weird
Try this alert(moment(String("2015-12-31 00:00:00")));
Moment JS
Solution 19 - Javascript
use the format 'mm/dd/yyyy'. For example :- new Date('02/28/2015'). It works well in all browsers.
Solution 20 - Javascript
This is not the best solution, although I simply catch the error and send back current date. I personally feel like not solving Safari issues, if users want to use a sh*t non-standards compliant browser - they have to live with quirks.
function safeDate(dateString = "") {
let date = new Date();
try {
if (Date.parse(dateString)) {
date = new Date(Date.parse(dateString))
}
} catch (error) {
// do nothing.
}
return date;
}
I'd suggest having your backend send ISO dates.
