function App() {
  const today = new Date();
  const tomorrow = dayjs(today).add(1, 'day').toDate();
  return (
    <div>
      <FullCalendar plugins={[dayGridPlugin]} locales={[jaLocale]} locale='ja'
       events={[
        {title:'event1', start: '2023-02-03', end: '2023-02-03'},

function App() {
  const today = new Date();

    setEvents([...events, event])
  }


  return (
    <div>
