How to use the “pattern” attribute In HTML

Using the “placeholder” attribute:

The “pattern” attribute allows you to specify a regular expression that the date input value must match. By using the “pattern” attribute, you can specify a custom date format that the user must enter. However, this approach does not change the format of the date displayed in the input field.

Syntax:

<label for="date">Enter a date (YYYY-MM-DD):</label>
<input type="date" name="date" id="date" pattern="\d{4}-\d{2}-\d{2}">

How to Change input type=”date” Format in HTML ?

The <input> element with type=”date” is used to allow the user to choose a date. By default, the date format displayed in the input field is determined by the user’s browser and operating system settings. However, it is possible to change the format of the date displayed in the input field using HTML.

JavaScript can be employed to enforce a specific format as browsers may not directly support changing the format.
Include a placeholder attribute with the desired date format, like “dd-mm-yyyy.”

Syntax:

<input type="date" name="date" id="date">
