title: Limit Pickup Dates in Date Picker
body: <p>I am building an online store using Shopify. My business is a food production business. My access to a commercial kitchen is limited to one day a week (Sunday) so I intend to collect orders Monday-Saturday, cook on Sunday, and have the orders available for pickup thereafter. I already have much of the code that I need loaded into my Shopify theme. To start off, I used the custom code at this LINK <a href="https://shopify.dev/tutorials/customize-theme-add-date-picker-for-delivery-dates" rel="nofollow noreferrer">https://shopify.dev/tutorials/customize-theme-add-date-picker-for-delivery-dates</a></p>
  <p>However I need further customization...</p>
  <p>I need help customizing the Date Picker available dates based on the day of the week that the order is placed.</p>
  <p>Rules below:</p>
  <ul>
  <li>An order placed Monday-Saturday, could be picked up as early as Monday next week and any day after that, but not sooner;</li>
  <li>An order placed on Sunday cannot be picked up until the following Monday (not the next day), but could be picked up on any day after that;</li>
  <li>No pickups on Sundays at all</li>
  </ul>
  <p>EXAMPLE:</p>
  <ul>
  <li>Monday 5/10 - earliest pickup Monday 5/17</li>
  <li>Tuesday 5/11 - earliest pickup Monday 5/17</li>
  <li>Wednesday 5/12 -  earliest pickup Monday 5/17</li>
  <li>Thursday 5/13 -  earliest pickup Monday 5/17</li>
  <li>Friday 5/14 -  earliest pickup Monday 5/17</li>
  <li>Saturday 5/15 -  earliest pickup Monday 5/17</li>
  <li>Sunday 5/16 -  earliest pickup Monday 5/24</li>
  <li>No pickups on Sundays</li>
  </ul>
