Can you turn off a survey during different times?

I think @curiousinengland refers to having the form only active during opening hours not when a business is close. The link you mentioned only allows to close it, but won’t reopen the next day.

There is no native option to do that, but you can embed the Typeform in Javascript, only if the page is loaded while the current time being in the active hours.

Something like this:

<div id="tf"></div>
<link rel="stylesheet" href="//embed.typeform.com/next/css/widget.css" />
<script src="//embed.typeform.com/next/embed.js"></script>
<script>
  function isBusinessHours() {
    var now = new Date();
    var hour = now.getHours();
    return hour >= 9 && hour < 18; // 9 AM to 6 PM
  }

  if (isBusinessHours()) {
    window.tf.createWidget('<form-id>', {
      container: document.getElementById('tf'),
      hidden: { url_form: window.location.href }
    });
  }
</script>
