# Date ranges tab

The Google Analytics Data API allows up to [four date ranges](https://developers.google.com/analytics/devguides/reporting/data/v1/rest/v1beta/DateRange) to be specified per report request. A minimum of one date range is always required. If more than one date range is used, a special dimension called `DateRange` must be added as an output field in order to separate stacked output rows.
