Getting Serious About Date Intelligence
Date intelligence refers to a wide array of semantic modeling patterns and functions that enable analysis across time periods. In this chapter and throughout this book, we use date intelligence to refer to this broad set of semantic modeling patterns and to distinguish the concept from DAX time intelligence functions. This is done for two reasons. First, to be more technically precise, date intelligence deals with dates (days, months, years), not time (hours, minutes, seconds). Second, DAX time intelligence functions are generally only useful if dealing with a standard (Gregorian) calendar, but many businesses use a financial calendar that is different than a standard calendar year. The broad concept of date intelligence is applicable to both the standard (Gregorian) calendar as well as custom financial calendars.
