Not always in all businesses the week starts from Sunday. The result of this measure would be the day number of week starting from Sunday as 1, ending Saturday as 7. here is the DAX statement: Day Number of Week = WEEKDAY(LASTDATE(DimDate)) Using LastDate function we get the date value of the current filter context, and wrap it inside a WeekDay function to fetch the day number of week. However, we calculate it again, just in case you use the built-in date table. We already have the day number of week in the DimDate provided by AdventureWorks. To start the solution letвЂ™s first find out what is the day number of week for any given date. Select FullDateAlternateKey as the date column.Д¬reate a table visual with CalendarYear, EnglishMonthName, DayNumberOfMonth, and EnglishDayNameOfWeek, and SalesAmount at the end of your date field to get it working.Д«ecause in this example we are going to use DimDate as our date table, select this table in the list of fields (in report tab, or data tab), and mark it as date table. all below calculations would work even if you use the built-in date table, you just need to add. * for week to date calculation to work it is not mandatory to have a date table, you can even use the built-in date table of Power BI. Create a connection between these two tables based on DateKey (from DimDate), and OrderDateKey (from FactInternetSales). If you want to use this example create a Power BI file connected to AdventureWorks data source and load FactInternetSales, and DimDate into the model. One of the methods is using functions such as DatesBetween and WeekDay to calculate the period between first day of the week and the date of the filter context.

There are many ways to calculate week to date. However, for calculating Week to Date there is no built-in function. There is a set of functions for calculating Year to Date (TotalYTD), Quarter to Date (TotalQTD), and Month to Date (TotalMTD). If you want to learn more about Power BI, read Power BI book from Rookie to Rock Star. So here in this post, I will explain a method to do week to date calculation with DAX. I have found it quite a demand for some of businesses, as many of businesses work on a weekly periods rather than monthly. However, there is no calculation for Week to Date built-in. There are a number of pre defined DAX time intelligence calculations that help you to get analytics over time, such as year to date, same period last year, and etc.
