    ul = document.getElementById("list"),
    temp,
    li,
    i;

for ( i = 0; i < 12; i += 1) {
    temp = getTuesdays(i, 2023);
    meetingTuesdays.push(temp[1]);
    li = document.createElement("li");
    li.textContent = temp[1];
    ul.appendChild(li);

    meetingTuesdays.push(temp[3]);
    li = document.createElement("li");
    li.textContent = temp[3];
