Displaying today's omer count

hebcal-omer.html

<div id="hebcal-omer"></div>
<script defer>
function pad2(number) {
  if (number < 10) {
    return '0' + number;
  }
  return '' + number;
}
let dt = new Date();
if (dt.getHours() > 19) {
  dt.setDate(dt.getDate() + 1);
}
const isoDate = [dt.getFullYear(), pad2(dt.getMonth() + 1), pad2(dt.getDate())].join('-');
const url = `https://www.hebcal.com/hebcal?v=1&cfg=json&o=on&lg=s&start=${isoDate}&end=${isoDate}`;
fetch(url, {method: 'GET', credentials: 'omit'})
  .then(response => response.json())
  .then(data => {
    if (data.items && data.items.length) {
      for (const item of data.items) {
        if (item.category === 'omer') {
          console.log(item);
          // You might also choose to display item.omer.count.en or item.omer.sefira.he
          document.getElementById('hebcal-omer').innerText = item.title;
        }
      }      
    }
  });
</script>

Thanks for the feedback. We've updated the gist to use the local date/time object instead of the toISOString() function
