{
  "events": {
    "-MkYg...": {
      "name": "Event 1",
      "date": "2022-01-01"
    },

      "name": "Event 2",
      "date": "2022-01-02"
    },
    ...
  }
}

const firebase = require('firebase/app');
require('firebase/database');

const firebaseConfig = {
  // Your Firebase config here
};

firebase.initializeApp(firebaseConfig);
const database = firebase.database();

const startDate = '2022-01-01';
const endDate = '2022-01-31';

database.ref('events')
  .orderByChild('date')
  .startAt(startDate)
  .endAt(endDate)
  .once('value', (snapshot) => {
    const events = snapshot.val();
    console.log(events);
  });

{
  "events": [
