Date and Time Functions (DAX)
Many of the date and time functions in DAX are very similar to the Excel date and time functions. However, DAX functions use a datetime data type, and can take values from a column as an argument. DAX also includes a set of time intelligence functions that enable you to manipulate data using time periods, including days, months, quarters, and years, and then build and compare calculations over those periods.
