I want to change the range of the week attribute from Monday - Sunday to Saturday - Friday instead. Is it possible to allow a custom range for the week attribute?
No, it is not possible to edit date ranges for calculated attributes. You can create a standard calculated attribute but that only applies to COUNT and D_COUNT metric aggregators. For more information see the article: Explore recipe: Using a Sunday to Saturday week attribute.
For the original conversation, see Allow custom range for Week attributes Answered.
