When creating a calculated metric, how far back does the preview show data for?

When creating a calculated metric, the preview date range can be selected by using the “Preview Date” drop-down in the Calculated Metric Builder. This will allow you to see how your calculated metric performs for different periods of time, such as last week, last month, last quarter, etc.
