How to Calcuate MTD, QTD and YTD in Power BI

Calculating the month to date, year to date, or quarter to date is not as daunting as you think in DAX. However, there are few stepst that are needed before you can get these function to provide the information that you are looking for.  These are all a part of Time Intelligence Function in DAX. 

What do you need?

  1. Calendar Table
  2.  Time Series Data

You might be wondering on why you need a Calendar Table. The reason that this is so important is that Time Intelligence function work off a continuous date field. So if your data has whole in it, the funcitons will not work. To give you an indication of this, I you didnt have a sale on 1/1/2020 and there is no date. This would create a whole in your data. 

If you dont have a Calendar Table you can easily create one with the following Table function. You are going to go to New Table in the Modeling heading at top ribbon. 

The CALENDAR function works like this CALENDAR(Start Date,End Date)

Date = CALENDAR(DATE(2020,1,1),DATE(,2020,12,31)

Now we can connect our date table to our fact table. Simplly click the relation icon and the far right and setup a 1 to many relation from the Date Tabel to the Fact Table.
