¿Hay alguna manera más fácil de hacer esta parte anterior? Intenté restar dos fechas pero me da un año incorrecto. He intentado esto

 new Date(date1 - date2);

Pero me da 2024, sé que no es posible tener una fecha anterior a 1970, pero ¿hay alguna otra forma de hacerlo?

 secondsTxt.innerText = seconds; minutesTxt.innerText = minutes; hoursTxt.innerText = hours; daysTxt.innerText = days; monthTxt.innerText = months; yearTxt.innerText = years; // const days = Math.floor(seconds / 3600 / 60) // const hours = Math.floor(seconds/3600) }; setInterval( countDown, 1000 );
