Scheduling recurring queries is available now in BigQuery since September 2018

You can use 3rd party solution or develop your own using client of your choice
https://cloud.google.com/bigquery/docs/reference/libraries
For example,
You can use App Engine Cron Service to automate BigQuery query execution https://cloud.google.com/appengine/docs/java/config/cron https://cloud.google.com/appengine/features/#cron https://cloud.google.com/bigquery/bigquery-api-quickstart
Or, you can use Google Apps Script to script BigQuery query with a Time based trigger to execute that script
