function DateRangePicker() {
  const [dateRange, setDateRange] = useState<DateRange>({
    startDate: null,
    endDate: null,
    selecting: false,
    hoverDate: null,
    anchorDate: null
  });

  const handleDateSelect = (date: Date) => {
    setDateRange(prev => {
      if (!prev.selecting) {
        return {
          startDate: date,
          endDate: date,
          selecting: true,
          hoverDate: date,
          anchorDate: date
        };
      }
      // Complete the selection
      return {
        startDate: prev.anchorDate,
        endDate: date,
        selecting: false,
        hoverDate: null,
        anchorDate: null
      };
    });
  };

  return (
    <Year 
      year={2024}
      dayHeaderStyle="tiny"
      monthCutoff="truncate"
      weekendDays={[6, 0]}
      dateRange={dateRange}
      onDateSelect={handleDateSelect}
      onDateHover={(date) => setDateRange(prev => ({ ...prev, hoverDate: date }))}
      size="l"
      fontProportion={100}
      magnify={true}

  );
}
```
