Something like this should do the trick:

cons ref = firebase.database.ref("calendar/events");
ref.once("value").then((snapshot) => {
  let result = {};
  snapshot.forEach((daySnapshot) => {
    result[daySnapshot.key] = [];
    daySnapshot.forEach((eventSnapshot) => {
      result[daySnapshot.key].push(eventSnapshot.val());
    })
  })
  console.log(result);
});

So we load all data from the database and then use two nested forEach loops to handle the dynamic levels underneath, and result[daySnapshot.key] to get the date key.
