Min and max date

Set mininum and/or maximum dates to limit users to choose from a specific period in time

Use from... and to... props to control time frames


function MinMaxExample() {
  const today = new Date();
  const [selectedDay, setSelectedDay] = useState(today);
  const max = today.getFullYear() + 5;

  return (
    <Calendar
      mode="single"

      toYear={max}
      selected={selectedDay}
      onSelect={setSelectedDay}
    />
  );
}function MinMaxExample() {
  const today = new Date();
  const [selectedDay, setSelectedDay] = useState(today);
  const max = today.getFullYear() + 5;

  return (
    <Calendar
      mode="single"
