How to change datetime to local timezone in Reactjs?

I am currently using data from Jikan Api. The datetime data is like this "broadcast": { "day": "Saturdays", "time": "01:53", "timezone": "Asia/Tokyo", "string": "Saturdays at 01:53 (JST)" }, is there anyway to change it into local time?

I searched across the web and found nothing like this. Mostly they are about formatting full datetime.

You can use a javaScript library called luxon. I made an example please check my stackblitz.

import React, { useState, useEffect } from 'react';
import { DateTime } from 'luxon';


//you can replace this data to the one from API
const jikanapiData = {
  data: {
    broadcast: {
      day: 'Saturdays',
      time: '01:53',
      timezone: 'Asia/Tokyo',
      string: 'Saturdays at 01:53 (JST)',
    },
  },
};

const dayMap = {
  Mondays: 1,
  Tuesdays: 2,
  Wednesdays: 3,
  Thursdays: 4,
  Fridays: 5,
  Saturdays: 6,
  Sundays: 7,
};

function App() {
  const getLocalBroadcastTime = () => {
    //convert day to weekday number in dayMap
    const broadcastWeekday = dayMap[jikanapiData.data.broadcast.day];
    if (!broadcastWeekday) return null;

    //get the current time from jikanapiData
    let now = DateTime.now().setZone(jikanapiData.data.broadcast.timezone);
    //reset time to midnight
    let broadcastDate = now.startOf('day');

    //match current weekdday number and broadcast weekday
    while (broadcastDate.weekday !== broadcastWeekday) {
      broadcastDate = broadcastDate.plus({ days: 1 });
      console.log(broadcastDate);
    }

    //set hour and minute from jikanapiData
    const [hour, minute] = jikanapiData.data.broadcast.time
      .split(':')
      .map(Number);
    //combine date and time for convering to local time
    const broadcastDateTime = broadcastDate.set({ hour, minute });

    //convert the result to the local timezone on your pc system
    return broadcastDateTime.setZone(
      Intl.DateTimeFormat().resolvedOptions().timeZone
    );
  };

  const localTime = getLocalBroadcastTime();

  return (
    <div className="App">
      <div>
        <strong>Local Broadcast Time: </strong>
        {localTime ? localTime.toFormat('cccc, hh:mm a') : 'Unknown'}
      </div>
    </div>
  );
}
export default App;
