Usage

import {
  TimezoneRangePicker,
  type OnApplyParams,
  type TimezoneData,
} from "react-timezone-range-picker";
// Should import the css to make sure the application works
import "react-timezone-range-picker/style.css";

const DEFAULT_TIMEZONE = {
  name: "Asia/Tokyo",
  longName: "Japan Standard Time",
  utcOffset: "+09:00",
};

const DEFAULT_RANGE = {
  startDate: "2025-06-10",
  startTime: "09:00:00",
  endDate: "2025-06-11",
  endTime: "18:00:00",
  timezone: DEFAULT_TIMEZONE,
};

type TzRange = {
  startDate: string | null;
  startTime: string | null;

  endDate: string | null;
  endTime: string | null;

  timezone: TimezoneData;
};

function App() {
  const [range, setRange] = useState<TzRange>(DEFAULT_RANGE);

  const handleTimeRangeApply = ({
    startDate,
    startTime,
    endDate,
    endTime,
    timezone,
  }: OnApplyParams) => {
    setRange({ startDate, startTime, endDate, endTime, timezone });
  };

  return (
    <TimezoneRangePicker
      {...range}
      onApply={handleTimeRangeApply}
      buttonStyle={{ height: "50px", fontSize: "13px", fontWeight: 300 }}
