This video shows you how to use time intelligence functions in DAX to return values from the start and end of a period. You'll learn how to use the FirstDate and LastDate functions as filter arguments for the Calculate function. You'll also see a range of functions used to return the start and end dates of yearly, quarterly and monthly intervals. The video also explains the ClosingBalance and OpeningBalance functions and explains how OpeningBalance is different to using the StartOf interval functions. You'll also learn how to work with incomplete date ranges and how to use the FirstNonBlank and LastNonBlank functions to return values even when your data model doesn't contain values for the start or end of standard intervals.
