JS Date - just take the date, without the time

Question

I'm doing a countdown on a cms. I have to modularize this. Modularizing is creating fields to enter information without messing with the code. Being able to change any information available without changing the text or values ​​in the code.

Building this structure or form, it provides an input to put the date. But if I put "2021/07/14", it shows me as "2021/07/13, 21:00". I only need the date as this time will be defined in another field.

The problem is that it already takes that date and turns it into milliseconds.

How can I work this date and change this time??

For your interest, the CMS is Liferay

function orangeWeeek() {
    let dataliferay = new Date($main.contagemregressiva.contagemregressiva_data.getData() $main.contagemregressiva.contagemregressiva_hora.getData())
    console.log(dataliferay)
    

    // Countdown
    function countdown() {
        let tagDay = document.getElementById("orangeWeek_countdown_time_days");
        let tagHours = document.getElementById("orangeWeek_countdown_time_hours");
        let tagMinutes = document.getElementById("orangeWeek_countdown_time_minutes");

        let futureDate = $main.contagemregressiva.contagemregressiva_data.getData()
        
        // Update countdown
        function updateCountdown() {
            const currentDate = new Date();
            const difference =  futureDate - currentDate;
            
            // Calculate the values
            const days = Math.floor(difference / 1000 / 60 / 60 / 24);
            const hours = Math.floor(difference / 1000 / 60 / 60) % 24;
            const minutes = Math.floor(difference / 1000 / 60) % 60;

            insertValuesHtml(days, hours, minutes)
        }
        
        // Insert values into html
        function insertValuesHtml(days, hours, minutes){
            tagDay.textContent = check_lessThanTen(days);
            tagHours.textContent = check_lessThanTen(hours);
            tagMinutes.textContent = check_lessThanTen(minutes);
        }
        
        // Check if the value is less than ten
        let check_lessThanTen = variable => variable < 10 ? '0' + variable : variable;

        updateCountdown()
        setInterval(() => {
            updateCountdown()
        }, 1000);
    }countdown()

}orangeWeeek()

$main.contagemregressiva.contagemregressiva_data.getData() this here is a template language called velocity. It's the language I use in liferay to call form/structure fields
