Conditional logic is an important concept for programming in general, and DAX is no different. There are many circumstances where we want to present different values for a measure or column based upon a series of conditions or circumstances; for example, if a particular day is a workday or weekend, or if a value is even or odd. In this recipe, we will learn how to use conditional logic in DAX to create a custom column that calculates the quarter for a nonstandard fiscal year that runs from June to May instead of from January to December using two different conditional logic DAX functions, IF and SWITCH.
