const date1 = new Date(Date.UTC(1906, 0, 10, 10, 0, 0)); // Wed, 10 Jan 1906 10:00:00 GMT
const date2 = new Date(Date.UTC(1906, 0, 10, 11, 0, 0)); // Wed, 10 Jan 1906 11:00:00 GMT
const date3 = new Date(Date.UTC(1906, 0, 20, 10, 0, 0)); // Sat, 20 Jan 1906 10:00:00 GMT

  day: "numeric",
  hour: "numeric",
  minute: "numeric",
});
console.log(fmt1.format(date1)); // '1/10/06, 10:00 AM'
console.log(fmt1.formatRange(date1, date2)); // '1/10/06, 10:00 – 11:00 AM'
