A scheduled Cloud Function deployed with the Firebase CLI will be the proper way to update your data in firebase. Your can run a scheduled function which can be triggered at a specific time (everyday or week however you want) and you can update your variable in the database inside the function. Here is a sample from firebase official documentation : 

exports.scheduledFunctionCrontab = functions.pubsub.schedule('5 11 * * *')
  .timeZone('America/New_York') // Users can choose timezone - default is America/Los_Angeles
  .onRun((context) => {
  console.log('This will be run every day at 11:05 AM Eastern!');
  return null;
});

Read documentation here : https://firebase.google.com/docs/functions/schedule-functions#write_a_scheduled_function
