## Help with Measure - Daily Average excluding weekends

Hello,

Hoping this is a simple solve, I just don't have the experience to figure it out yet.

My dataset has a 'Measure X' that represents a count of events. I'd like to create a measure that can calculate the daily average events for the previous 14 days, excluding any weekend days. Bonus points if there's a way to specifically make it also exclude US holidays (but I'm fine if that's not possible). We only get events on working days, so when I try to do just a simple relative date filter, the average gets diluted by the weekends/holidays.

Could someone help me with the DAX on this?

Thank you.

It is recommended to prepare a calendar table with a WorkingDay column which has 1 for working days and 0 for weekends/holidays. Create a relationship between the original table and the calendar table on Date column. Then you can try the following measure

``````Avg of Measure X =
VAR _lastDate =
TODAY ()
RETURN
DIVIDE (
CALCULATE (
[Measure X],
DATESINPERIOD ( 'Calendar'[Date], _lastDate, -14, DAY )
),
CALCULATE (
COUNT ( 'Calendar'[Date] ),
DATESINPERIOD ( 'Calendar'[Date], _lastDate, -14, DAY ),
'Calendar'[Working Day] = 1
)
)
``````

I have created a sample attached at bottom. Hope it helps.

DAX has a WEEKDAY function

https://docs.microsoft.com/en-us/dax/weekday-function-dax

If you are using a Date Table, you can create a Calculated Column and determine Weekday.

If not, simply create a new column in your data table.

Then add a FILTER to your Measure and exclude Days 6 and 7 (depending on which return_type you decide to use).

Hope this helps.
