Countdown for goods?

Question

JavaScript

var dateTimeForProd = [];
    $('.project-manager p.time').each(function(e) {

        var time = new Date($(this).attr('data-time')).getTime();
        dateTimeForProd.push(time);
    });


    const timer = (date) => {
      let now = Date.now();

      let distance = date - now;

      let days = Math.floor(distance / (1000 * 60 * 60 * 24));
      let hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
      let minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
      let seconds = Math.floor((distance % (1000 * 60)) / 1000);

      if (distance < 0) {
        clearInterval(x);
      }
    }

    let x = setInterval(function () {
      for(var i = 0; i < dateTimeForProd.lenght; i++) {
          
      }
    }, 1000);

Hello, the problem is this, I can’t figure out how to correctly link each count to my product, so far there is such a code
