I have the following code in a template:
<?= $this->Form->date('selected_date', ['required' => true]) ?>
This displays a lovely new dynamic date picker, but with the US format "mm/dd/yyyy". What I want is "dd/mm/YYYY"
In app.php I've set the APP_DEFAULT_LOCALE to en-GB.
In AppController.php I've set the following:
I18n::setLocale('en-GB');
Time::setDefaultLocale('en-GB'); // For any mutable DateTime
FrozenTime::setDefaultLocale('en-GB'); // For any immutable DateTime
Date::setDefaultLocale('en-GB'); // For any mutable Date
FrozenDate::setDefaultLocale('en-GB'); // For any immutable Date
How do I change the format? I can't find anything in the docs or online.
You can't change it, at least there's no reliable, cross browser/device compatible way, the control is rendered by the browser, and the current state of things is that browsers use the locale the browser currently runs in to format the control.
If you want something solid, then you'll have to use a custom JavaScript datepicker. If you want to walk on the edge, look into web components.

I've added the
showLastUpdateTime: true,
line to my docusaurus.config.js, and the date is showing at the bottom of documents, but the format is US (which doesn't work for the majority of the world). I need it to be unambiguous, or not 'wrong' :D
Does anyone know how I can change this?
I don't believe you can explicitly set the format manually - it uses the default Intl.DateTimeFormat constructor under the hood - however you can manipulate it by setting the base locale of your site to something other than the default.
To do this, you need to leverage the i18n configuration - add this to your docusaurus.config.js:
i18n: {
defaultLocale: 'en-GB',
locales: ['en-GB']
}
Substitute en-GB for whatever your desired locale is, and you'll see the date show in that locale's format, so in the UK it's dd/MM/yyyy.
When I create a post, in the front matter I have to insert layout, title, date etc. My concern is regarding date front matter. It is very inconvenient to insert date time and time offset in date field manually.
I'm not able to figure out how to do this automatically. I want the front matter date to update automatically with system time.
The date variable in front matter is an optional variable that you can set to be able to override the date that you set when you title your post according what Jekyll is looking for (i.e. 2019-12-14-post-title.md). It should only refer to the date the post was originally made, and not the current system date. Except for certain edge cases, you really shouldn't have to define date in the front matter.
You can use Liquid templating to post the current time to a page by passing the "now" keyword to date in your liquid template as follows:
This page was last updated at {{ "now" | date: "%Y-%m-%d %H:%M" }}.
to get the the output:
This page was last updated at 2019-12-14 17:48.
However this method has a big drawback for Jekyll usage, because it will refer to the current date when the page was last generated from the template and not when the page is being visited by the user.
The best way to access the current system time is likely to use javascript instead. This is fairly easy depending on your familiarity with the language, but essentially you can make a Date object and then output the info you are looking to display. Here is a quick snippet I made that shows a couple methods that act on the Date object to output different values such as the date, time, and year:
<!DOCTYPE html>
<html>
<body>
<h3>The toDateString() method converts a date to a date string:</h3>
<p id="demo1"></p>
<h3>The toLocaleTimeString() method outputs formatted time:</h3>
<p id="demo2"></p>
<h3>The getFullYear() method outputs the year:</h3>
<p id="demo3"></p>
<script>
// create date object
var d = new Date();
// use toDateString() to output formatted date
document.getElementById("demo1").innerHTML = d.toDateString();
// use toLocaleTimeString() to output formatted time
document.getElementById("demo2").innerHTML = d.toLocaleTimeString();
// use getFullYear() to output year
document.getElementById("demo3").innerHTML = d.getFullYear();
</script>
</body>
</html>
W3schools has a good rundown of the Date object and how to format output if you need more examples and reference on usage.
If you need to know how to use Javascript with Jekyll there is a helpful post on Jekyll Talk that will help.
First of all, you do not HAVE to insert 'layout, title, date etc'. You can use Front Matter defaults for them. This only makes sense for the layout as the title can or should be default, nor the date.
The date MUST be set in your filename and can be overridden in the Front Matter. Please note that this is ONLY true for the built-in collection posts. If you use a custom collection you do not need a date at all.
However, if you choose to use posts nevertheless and you want to add the date automatically, there is only one real option: Use a CMS that automates this input, like Forestry.io or CloudCannon.
I'm building a cakephp 3 app (cakephp v3.3.2 that is) and I have a problem getting dates displayed in the chosen locale (de_DE).
The database field in my example is invoice_date, which is of type DATE (stored in a mysql DB).
I want to use a date picker in the web page ("zebra_datepicker"), so in the view I use a single text entry field for the date instead of the three drop-downs that are displayed by default:
echo $this->Form->input('invoice_date', [ 'type' => 'text' ]);
To get the date displayed in the German format dd.mm.YY I changed the global locale setting to
ini_set('intl.default_locale', 'de_DE');
in config/bootstrap.php.
For testing, I created a new record in the database and set the invoice_date to 2016-09-02 (Y-M-D).
If I call the edit action of my controller now, I get a default value of 02.09.16 in the form, which is correct. But if I submit the form back, the database value of the field is changed into 2002-09-16!
Do I need some extra code in the controller to change the date format back into its original form? Is this a bug in the localization code of cakephp or did I miss something? Note, that my controller just uses patchEntity to process the posted data.
I already tried adding date('invoice_date', 'dmy') in the validationDefault method of the table object, but this didn't change anything:
$validator
->date('invoice_date', 'dmy')
->requirePresence('invoice_date', 'create')
->notEmpty('invoice_date');
Thanks for your help!
I just found the solution to my problem: in bootstrap.php, I had to add:
Type::build('date')->useLocaleParser();
Type::build('datetime')->useLocaleParser();
With that, I can enter dates like 31.12.16 (d.m.y) and the date gets correctly saved in the database. This works with the simple validator:
$validator
->date('invoice_date')
->notEmpty('invoice_date');
To also support dates like 31.12.2016 (d.m.Y), I had to add an extra parameter to the date validator, like this:
$validator
->date('invoice_date', 'dmy')
->notEmpty('invoice_date');
Is there a way to display a date in an input different from the format I want to submit.
For example I have to submit a date in "yyyy-mm-dd" format but I want to display the date in another format : "dd/mm/yyyy" (french display).
Is there a good tip to do that with Datebox for jQuery Mobile (an option I didn't see ?)
I think I have to cheat in creating an input hidden with the good form format and another one with the format to display (and not submitted), but maybe a better solution exists.
Any ideas ?
Your best bet is to indeed use 2 inputs - but, it's pretty easy to do, and using a callback on the set event, you can even make datebox do the second format for you.

(Note: I just added the demo, so you didn't miss it earlier)
Just a small addition
It should be "overrideDateFormat":"%d/%m/%Y" in the HTML inline options.
In http://dev.jtsage.com/jQM-DateBox2/demos/script/split.html it states "dateFormatOverride":"%d/%m/%Y"} however this is incorrect and doesn't work. Just a heads up for anyone else with this issue.
Yes you need to use this method.
<!-- fix american date formatting -->
<script type="text/javascript">
jQuery.extend(jQuery.mobile.datebox.prototype.options, {
'overrideDateFormat': '%d/%m/%Y',
'overrideHeaderFormat': '%d/%m/%Y'
});
</script>
I'm trying to set the format for a jquery datepicker element with the date format returned by Zend_Locale::getTranslationList('date', $locale);
My problem is zend returns the string 'dd/MM/yyyy' for the date format but jquery expects only 2 characters for the year ie 'dd/mm/yy', so it enters the year twice 20112011
Is there some option that can be passed to either zend or jquery to make them work in the same manner? I've read through the docs and can't seem to find anything
Many thanks for your help in advance!
I have used jquery date picker in python-django framework when I give date format as dd/mm/yyyy format it returns 20112011 then i have corrected it to dd/mm/yy and it returned 2011 only. you can specify in your datepicker css class to specify the date format as dd/mm/yy.
Iam not sure if this is what you're looking for but:
// use german local, change it to our needs :-)
$locale = new Zend_Locale('de_DE');
$result = Zend_Locale::getTranslationList('date', $locale);
// returns dd.MM.yy (german!)
echo $result['short'];
