Hey guys!
All right with you?
In this post I would like to bring my opinion on the best way to create a calendar table. This table, often used for BI/Analytics scenarios, serves to aggregate data by different time/date dimensions and is present in almost 100% of reports and BI projects, making it a good practice to use it.
It is worth remembering that it is a bad practice to use the default Power BI date hierarchy (See more about this by clicking in this link here), and should only be used in very small, occasional projects or by novice users.
Any scenario other than this should require the use of Calendar tables instead of using Power BI's default hierarchy, which creates a very basic internal calendar table for each date-type column that exists in the model, thus impairing performance. of model.
Many argue that it is better to create using SQL, others in M, others in DAX and the discussion goes on longer than it should.
How best to create a calendar table
There are several very interesting articles about this discussion and I would highlight the article Power BI Date or Calendar Table Best Method: DAX or Power Query? as one of the best I've read on the subject.
And I'll give my opinion on this:
| DAX | M / PowerQuery | SQL | |
|---|---|---|---|
| I can create a calendar table | Yes | Yes | Yes |
| It's easy to create the calendar table | Yes | Yes | Yes |
| My calendar table respects the range of my data | Yes | Yes, using parameters | Yes, filtering in the query |
| I can calculate national, mobile and state holidays | No | Yes, but it takes a lot of work | Yes |
| Can I reuse it in other reports (without duplicating code) | No | Yes, but only using Dataflow | Yes |
| Can I reuse using other Dataviz tools | No | No (unless using PowerQuery online or ADF/Synapse/Fabric) | Yes |
Now that I have expressed my opinion, in which I believe that the calendar table would be better used if created in a DW base using SQL, for better reuse of data in any scenario, project, report or tool, I will show you how to create your table calendar using SQL.
How to Create a Calendar Table Using SQL (Including Holidays)
Back on July 29, 2015, just 5 days after the official launch of Power BI (and which would only be available in Brazil several months later), I had already posted the article How to calculate working days in SQL Server (Table dCalendar), where I show how to create a calendar table using SQL.
In this post, I would like to update this solution and present you with some calendar table models, so that you can use the model that best suits your needs.
Model 1 - Simplified table
If you need something simple, fast and objective, without worrying about holidays and working days, this is a good option for you.

Model 2 - Simplified Table IN ENGLISH
If you need something simple, fast and objective, in the ENGLISH language, without worrying about holidays and working days, this is a good option for you.
The last parameter of the function is the number of months of the FiscalYear, which add N months in the fiscal columns.
