FotGOD,
сделайте минимальный макет

чтото типа такого я пробовал:

function timer() {
   let day = document.getElementById('day_id').value;
   let hour = document.getElementById('hour_id').value;
   let minute = document.getElementById('minute_id').value;
   let second = 59;
   const now = new Date(),
     newTime = new Date(now.getFullYear() + 1, 0, 1),
     diff = newTime.getTime() - now.getTime(),
     days = day,
     hours = hour,
     minutes = minute,
     seconds = 59 - now.getSeconds();
 
   let st = '';
   if(seconds==0){
       minutes--;
   }
   if(minutes==0&&seconds==0)
   {
       hours--;
   }
   if (diff <= 0) {
    st  = window.open("http://google.com");

   } else {
     st = `${days} days, ${hours} hours,${minutes}minutes,${seconds}seconds`;
   }
   document.getElementById("showtime").innerHTML = st;
 }
 
 document.getElementById('start').addEventListener('click', () => setInterval(timer, 1000));
 timer();
