Creating a Calendar in ExcelĪnother way to create a calendar is using an Excel spreadsheet. This works in exactly the same way (and suffers from the same drawbacks), but it does at least give you more control over which dates are generated. This was all very quick, but also not that useful, as you’re now going to have to add columns giving the year, month, quarter and so on for each date AND then do the same thing for each model that you create.Ī variation of the above is the CALENDAR function, which lets you specify a start and end date: Because the financial year ends in December, the function will generate a table containing all the dates for the months January through to December for the years 2018, 20: In this example the first date is 10 th February 2018 and the last date is 8 th January 2020. When you confirm, you’ll see that this formula Power BI will create a set of dates going from the first date it finds in your data model to the last. You could leave out the argument 12, since December – month 12 – is the default anyway: In this case, just assume that the fiscal year ends in December. Then use the CALENDARAUTO function to say what it will contain: To use this, click on the following tool found on the Modeling tab to create a new table: One of these is the CALENDARAUTO function. Creating a Calendar in DAXĭAX contains a couple of functions which will auto-generate a calendar table for you (this sounds like a good idea, but probably isn’t – read on). However, since dates are stored internally as numbers, I can’t see any reason not to use a date column as your primary key, as above. This doesn’t have to be a date you could use a separate numeric field instead. In addition, each date row should have a primary key (a unique field which tells you the date you’re looking at). In the example above, the table consists of all the dates in 2018, 20, since this is the lifespan of the transactions in the Sales worksheet. Thus, a calendar table should include one row for each date in your model in which you might be interested. What should a calendar table in Power BI look like? Here’s an example: Given that most people’s main interest in creating measures in DAX is to compare numbers across time periods, the second point is a bit of a clincher! The Requirements for a Calendar Without a calendar table these won’t work.
