php \> $dtZone = new DateTimeZone(‘UTC’);
php \> $dtString = ‘2019-02-31’;
php \> $dt = new DateTime($dtString, $dtZone);
php \> echo $dt-\>format(‘Y-m-d’);

Unfortunately I don’t know what your goal is.
The form element `Laminas\Form\Element\DateSelect` uses the [`Date` validator](https://docs.laminas.dev/laminas-validator/validators/date/) from laminas-validator. There will you find all supported constants:

Maybe you can describe exactly what you have in mind then we can better help.

Hello. 🙂
My english is terrible! Sorry about.
I builded a Form\Form and use inside Form\Element\DateSelect.
I see (in html ) Day-Select(01-31), Month-Select(01-12) and Year-Select(configure with max\_year and min\_year),
It works.
Unfortunately you can select 31.02.2019 and I see in database 2019-03-03.
I wanto to use in InputFilter:
‘options’ =\> [
‘messages’ =\> [
Validator\Date::ANY\_CONST =\> ‘message’
]
}
Greetings

Please check which date value the form returns after validation:
```php
if ($form->isValid()) {
var_dump($form->getData());
}
```

[email] =\> [test@example.de](mailto:test@example.de)
[confirm\_email] =\> [test@example.de](mailto:test@example.de)

Here a short example to demonstrate different values for validation:
```php
class ExampleForm extends Laminas\Form\Form
implements Laminas\InputFilter\InputFilterProviderInterface
{
public function init() : void
{
$this->add(
[
'name' => 'birthday',
'type' => Laminas\Form\Element\DateSelect::class,
]
);
}
public function getInputFilterSpecification() : array
{
return [
[
'name' => 'birthday',
'required' => true,
],
];
}
}
```
Validation with invalid value:
```php
$form = new ExampleForm();
$form->init();
$form->setData(
[
'birthday' => '',
]
);
var_dump($form->isValid()); // false
var_dump($form->getMessages()['birthday']['isEmpty']); // "Value is required and can't be empty"
```
With valid values:
```php
$form = new ExampleForm();
$form->init();
$form->setData(
[
'birthday' => '2020-07-01',
]
);
var_dump($form->isValid()); // true
```
```php
$form = new ExampleForm();
$form->init();
$form->setData(
[
'birthday' => [
'year' => '2020',
'month' => '07',
'day' => '01',
],
]
);
var_dump($form->isValid()); // true
```
Maybe it will help to find your problem.
