How can I change the language of hour & minute captions in forms?

Site URL: https://www.dlopezlaw.com/es/comunicacion

I am creating a multilingual site and have managed to do everything I need it to do except changing the time caption (Hour and Minute to Hora and Minuto) on the contact form on the Spanish version. I was able to follow a previous question to change the first name and last name caption but can't figure out how to do the same for the Hour and Minute (I am hiding the second option). 

Add to Page Settings > Advanced > Header

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
jQuery(function($){
    $(".field.hour.two-digits input").html(function() { 
          return $(this).html().replace("Hour", "new hour text");  
    });
      $(".field.minute.two-digits input").html(function() { 
          return $(this).html().replace("Minute", "minute new text");  
    });
});
</script>

Thank you! I tried to add it to the code I already had in there for the first name and last name translation and it is not working. Any thoughts? Here is what I currently have:

<script>
function addLoadEvent(func) {
 var oldonload = window.onload;
 if (typeof window.onload != 'function') {
   window.onload = func;
 } else {
   window.onload = function() {
     if (oldonload) {
       oldonload();
     }
     func();
   }
 }
} 
addLoadEvent(function() {  
 sqsFirstName = document.getElementsByClassName("caption")[0].innerHTML;
 myFirstName = sqsFirstName.replace("First Name", "Primer nombre");
 document.getElementsByClassName("caption")[0].innerHTML = myFirstName;

 sqsLastName = document.getElementsByClassName("caption")[1].innerHTML;
 myLastName = sqsLastName.replace("Last Name", "Apellido");
 document.getElementsByClassName("caption")[1].innerHTML = myLastName;
  
});

</script>

Keep my code & let me know. I will check again

Added it back and I still don't see a change. Thanks in advance for your help.

Remove code I sent and use this

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
jQuery(function($){
    $(".field.hour.two-digits .caption").html(function() { 
          return $(this).html().replace("Hour", "new hour text");  
    });
      $(".field.minute.two-digits .caption").html(function() { 
          return $(this).html().replace("Minute", "minute new text");  
    });
});
</script>

It's still not updating the caption.
