In the context of a worksheet bucketed by date, you can map date columns to which of the following?

Mapping date columns to two workbook variables for start and end date is particularly effective because it allows for a clear delineation of a time range within the worksheet. By utilizing both a start date and an end date variable, users can easily filter and analyze data within the specified timeframe. This approach provides flexibility in reporting and enhances the ability to track changes or trends over time.

Using two distinct variables also allows for more sophisticated analysis, as it accommodates varying time periods and can support comparisons or aggregations over that duration. In scenarios where data is bucketed by date, having defined start and end points is critical for precise insights and decision-making.

The other options do not align with the typical use cases encountered in mapping dates within worksheets. For instance, mapping to just one workbook variable would limit the analysis to a single date point, which is often not sufficient for comprehensive evaluations. Additionally, while mapping to two variables representing different time zones could be useful in certain contexts, it's not the standard practice for analyzing data bucketed by dates within a single worksheet. Lastly, stating that no mapping is necessary undermines the importance of structuring data effectively for analysis.
