because the value you get from the input is a string and you compare it to a number in your switch so you either convert the value to a number with Number() or parseInt() method or change number to strings in your switch

https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/valueAsNumber <-- just use this https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/number <-- with this instead of this:

button.onclick = function(){
  ...
};

button.onclick = function(){
  ...
};

and this:

<div class="container">
  ...
</div>

<div class="container">
  ...
</div>

use this:

<form id="form" class="container">
  ...
</form>

<form id="form" class="container">
  ...
</form>

and this:

const form = document.getElementById('form');

form.addEventListener(function(event) {
  event.preventDefault();
  ...
});

const form = document.getElementById('form');

form.addEventListener(function(event) {
  event.preventDefault();
  ...
});

by the way, you have a global variable don't use those that let day; should be inside the event handler you can even go deeper and use an array for the day names
