javascript - Program made to join you into ZOOM classes automatically doesn't work for first class?

Question

I have a program made to automatically join you into your ZOOM classes that works by checking the time, and if the time is equal to one of the join times inputted by the user (stored in localStorage) than it will use window.open to open the launch meeting page, and therefore join you into the ZOOM meeting using the inputted link (also in localStorage) Our school has A days and B days, half of your classes are on an A day, half on a B day except for advisory, The problem is, whether it is an A day or a B day, the program doesn't join you into your first class. My code is here.

var tst = localStorage.getItem("a1");
if (tst == null) {
  alert(
    "Hello, it appears that there was a problem retreiving your stored data, meaning either that you have cleared your browsing data or started using a new device or browser to access our service, or this is your first time. Either way, please enter your ZOOM links into their respective boxes below."
  );
}

function timeNow() {
  var d = new Date(),
    h = (d.getHours() < 10 ? "0" : "") + d.getHours(),
    m = (d.getMinutes() < 10 ? "0" : "") + d.getMinutes();

  return h + ":" + m;
}
function Aday() {
  tst = localStorage.getItem("a1");
  if (tst == null) {
    alert(
      "Hello, it appears that there was a problem retreiving your stored data, meaning either that you have cleared your browsing data or started using a new device or browser to access our service, or this is your first time. Either way, please enter your ZOOM links into their respective boxes below."
    );
  } else {
    if (counter === true) {
      alert("You will be joined into your A day classes");
      counter = false;
    }
  }

  if (timeNow() === localStorage.getItem("a1t")) {
    window.open(localStorage.getItem("a1"));
    setTimeout(Aday, 60000);
    return;
  }
  if (timeNow() === localStorage.getItem("a2t")) {
    window.open(localStorage.getItem("a2"));
    setTimeout(Aday, 60000);
    return;
  }
  if (timeNow() === localStorage.getItem("adt")) {
    window.open(localStorage.getItem("ad"));
    setTimeout(Aday, 60000);
    return;
  }
  if (timeNow() === localStorage.getItem("a3t")) {
    window.open(localStorage.getItem("a3"));
    setTimeout(Aday, 60000);
    return;
  }
  if (timeNow() === localStorage.getItem("a4t")) {
    window.open(localStorage.getItem("a4"));
    setTimeout(Aday, 60000);
    return;
  }
  setTimeout(Aday, 500);
}
var counter = true;

Either way, please enter your ZOOM links into their respective boxes below."

<h5>HOW TO USE</h5>
<p>
  This program works by constantly checking if you have a class, then if so,
  opening the launch meeting page for the correct class. You do not need to
  enter your ZOOM links every time, but you do need to keep this tab open.
  <br />
  <br />
  Please select whether today is an A day or a B day.
</p>
<script src="script.js"></script>
<button onclick="Aday()">A day</button>
<button onclick="Bday()">B day</button>
<p>
  If this is your first time using this service or you have recently cleared
  your browsing data, copy and paste the ZOOM links for your classes into their
  respective input boxes.
