Add Date Picker in Magento 2 Configuration Section Using system.xml

We’ll explore how to add a date picker in the Magento 2 configuration section using system.xml, showing step-by-step code and setup for admin panel integration.

Step1# open your module system.xml from app/code/NameSpace/ModuleName/etc/adminhtml

and following code in it

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../Config/etc/system_file.xsd">
    <system>
        <section id="yoursectionid" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
            <label>Custom Label</label>
            <tab>tabname</tab>
            <resource>NameSpace_ModuleNmae::config_modulename</resource>
            <group id="general" translate="label" type="text" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
                <label>General Settings</label>
                <!-- date picker field code start-->
                <field id="start_date" translate="label comment" sortOrder="4" type="date" showInDefault="1" showInStore="1" >
                    <label>Start Date</label>
                    <!-- here we pass class where we create date picker-->
                    <frontend_model>NameSpace\ModuleName\Block\DatePicker</frontend_model>
                </field>
                <!-- date picker field code end-->
            </group>
        </section>
    </system>
</config>

step #2 : Now we create DatePicker class in file DatePicker.php  at app/code/NameSpace/ModuleName/Block/ folder where we create date picker element

<?php
namespace NameSpace\ModuleName\Block;

use Magento\Framework\Registry;
use Magento\Backend\Block\Template\Context;

class DatePicker extends \Magento\Config\Block\System\Config\Form\Field
{
    /**
     * @var  Registry
     */
    protected $_coreRegistry;

    /**
     * @param Context $context
     * @param Registry $coreRegistry
     * @param array $data
     */
    public function __construct(
        Context  $context,
        Registry $coreRegistry,
        array    $data = []
    )
    {
        $this->_coreRegistry = $coreRegistry;
        parent::__construct($context, $data);
    }

    public function render(\Magento\Framework\Data\Form\Element\AbstractElement $element)
    {
        $element->setDateFormat("dd/mm/yy"); //set date as per requirment
        return parent::render($element);
    }
}

step 3# Now in your admin section you get this datepicker element as following
