Problem with countdown

I'm trying to make a countdown. I thought the logic was fine, but it seems that it does not work. It consists of a countdown that, when the desired date arrives, is automatically added 1 day and the counter starts again ... but apparently it does not start again. Some help? Thank you very much in advance.

        var futuro = new Date (2018,9,22,20,02); //año, mes-1, dia, hora, minutos  
        var actualiza = 1000; 
        function faltan()
        { 
            var ahora = new Date(); 
            var faltan = futuro - ahora; 
            if (faltan > 0){ 
            var segundos = Math.round(faltan/1000); 
            var minutos = Math.floor(segundos/60); 
            var segundos_s = segundos%60;

You have a couple of errors in your code, you are declaring twice the function faltan , one within the other. Another small detail is that when you calculate the days you do it using the variable horas when you should do it with horas_s . The solution I propose is to restructure this function in the following way:

var futuro = (new Date (2017, 10, 25, 15, 48, 10)).getTime();
var actualiza = 1000;

function faltan() {
  var ahora = (new Date()).getTime();
  var faltan = futuro - ahora;

  if (faltan > 0){
    var segundos = ~~( faltan / 1000 );
    var minutos = ~~( segundos / 60 );
    var horas = ~~( minutos / 60 );
    var dias = ~~( horas / 24 );

    var segundos_s = segundos % 60;
    var minutos_s = minutos % 60;
    var horas_s = horas % 24;
    var dias_s = ~~( horas_s / 24 );

    document.formulario.reloj.value = [
	  dias_s,
	  "dias :",
	  horas_s,
	  "horas :",
	  minutos_s,
	  "minutos :",
	  segundos_s,
	  "segundos"
	].join(' ');
	
	setTimeout("faltan()",actualiza);
	
  } else {
    futuro = new Date();
    futuro.setHours(futuro.getHours()+24);
    document.formulario.reloj.value = "0 dias : 0 horas : 0 minutos : 0 segundos";
  }
}
