How to unblock weekend delivery date picker?

[Az94]

Hi all,

Currently I am creating a delivery picker in the cart page. It is working. However, the calendar blocked all my weekends. 

My Questions: 

1. In which line of the existing code I can disable and enable the delivery date?

2. Can I make it mandatory where customer cannot check out if they didn't select the delivery date?

3. Can I have a buffer of 2 days from the "on date"? Example: today is 9/11/2024, customer can only select 2 days after the current date. 

Let me share the code. 

theme.liquid

{{ '//ajax.googleapis.com/ajax/libs/jquery/2.2.3/jquery.min.js' | script_tag }}

create a delivery date snippet

  {{ '//code.jquery.com/ui/1.9.2/themes/base/jquery-ui.css' | stylesheet_tag }}
  <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js" defer="defer"></script>

  <div style="width:300px; clear:both;">
    <p>
      <label for="date">Pick a delivery date:</label>
      <input id="date" type="text" name="attributes[date]" value="{{ cart.attributes.date }}" />
      <span style="display:block" class="instructions"> We do not deliver during the week-end.</span>
    </p>
  </div>

  <script>
    window.onload = function() {
      if (window.jQuery) {
        let $ = window.jQuery;

        $(function() {
          $("#date").datepicker({
            minDate: +1,
            maxDate: '+2M',
            beforeShowDay: $.datepicker.noWeekends
          });
        });
      }
    }
  </script>

snippet in cart page - cart.liquid

{% render 'delivery-date' %}
