How to select today from html date picker instead of just putting the date there using selenuim and testng for a maven project

I can not click the today button in calender. here is an example in this website <https://www.wufoo.com/html5/date-type/>. <input type="date"> this is the html for date i am talking about. how to select and click today button in this.

.

I could send the date value in the date input field. But I am expecting to click the today button instead of sending the date as input

Here is the pom.xml file

This is the test file

package org.example;
import io.github.bonigarcia.wdm.WebDriverManager;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.Test;
import java.time.LocalDate;
public class AppTest
{
public static WebDriver driver;
public LocalDate today = LocalDate.now();
@Test
public void wow() throws InterruptedException {
WebDriverManager.chromedriver().setup();
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("https://www.wufoo.com/html5/date-type/");
Thread.sleep(0500);
driver.findElement(By.xpath("//*[@id=\"main\"]/section[1]/div/p[3]/input")).click(); // want to click the calender button. but it is clicking the text input field
}
}

Refer the below working code with explanation:

public static void main(String[] args) {
// TODO Auto-generated method stub
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("https://www.wufoo.com/html5/date-type/");
WebDriverWait wait = new WebDriverWait(driver,Duration.ofSeconds(30));
// below line will accept cookies
wait.until(ExpectedConditions.elementToBeClickable(By.id("onetrust-accept-btn-handler"))).click();
// below 2 lines will get the next Monday in dd/MM/yyyy format
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("dd/MM/yyyy");  
LocalDateTime now = LocalDateTime.now();
String nextMonday = Objects.toString(dtf.format(now.with(TemporalAdjusters.nextOrSame(DayOfWeek.MONDAY))));
// below line will send next Monday's date to date picker input text box
wait.until(ExpectedConditions.elementToBeClickable(By.name("date"))).sendKeys(nextMonday);
}

Required imports:

import java.time.DayOfWeek;
import java.time.Duration;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.time.temporal.TemporalAdjusters;
import java.util.Objects;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

Result:

It's not easy to do, as far as opened calendar is actually not DOM element.
So 'user behaviour' as native click you can only simulate as clicking by coordinates (which I suggest you not to do).

However. you can pass date in input itself via sendKeys, that would be easiest solution in your case.

WebElement dateElement = wdwait.until(ExpectedConditions.visibilityOfElementLocated(new By.ByCssSelector("[type=date]")));
LocalDate currentDate = LocalDate.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("ddMMyyyy");
dateElement.sendKeys(currentDate.format(formatter));
