What feature would be used to compare two date ranges in a report?

The "Date range comparison" feature in Google Analytics allows you to select two distinct periods and view their data side-by-side within a report. This is essential for analyzing trends, identifying performance changes, and understanding the impact of marketing efforts or website updates over time. "Hourly, Day, Week, Month views in the time graph" change the granularity of the data displayed within a single date range, but do not compare two separate ranges. "Real-time reports" show current user activity and are not designed for historical date range comparisons. The "Account selector" is used to switch between different Google Analytics accounts, not to compare date ranges within a report.
