Datepicker is a date input method through a dialog that is specially designed to input the date. By using the datepicker, the user does not need to input date manually.

Many ways you can create a datepicker function on the input element. one of them by using jQuery UI. jQuery UI has provided a special function to display datepicker.For more details, let's look at the following steps.

$Creating Input Element using HTML

Open your Text editor and create new file.
Save as date.html. recomended to save and run it on Webserver such as XAMPP, Apache etc. Because this function sometime can't run except in webserver.
Add the HTML element as usual.

<head>
<title>DatePicker</title>
</head>
<body>
</body>
</html>

Create an input text for inputing date.

Date: <input type="text" id="date">

$Starting to code jQury UI script.

To write the jQuery UI Script we should open <script> tag. You can put it in element or in <body> or in <head> element.

$("#date").datepicker();

$Adding Animations.

There are many kind animation that was provided by jQuery UI for Datepicker such as show, slideDown, fadeIn, blind, bounce , clip, drop, fold, and slide. To add the animations on datepicker, select the input on more time and add the datepicker() function. then add the following parameter to datepicker().

$("#date").datepicker( "option", "showAnim", "animationname");

So, the script become like this.

$("#date").datepicker();
        $("#date").datepicker( "option", "showAnim", "slideDown");

Save the file and try to run. See the animation effect on your datepicker.
Change the animations as you want to make you more unserstand about this

To display the date of other month just add showOtherMonths: true and selectOtherMonths: true to datepicker() parameter mehtod.

$("#date").datepicker({
        showOtherMonths: true,
        selectOtherMonths: true
        });

To display mont and year select, add changeMonth: true, changeYear: true to datepicker parameter function.

$("#date").datepicker({
