Display Data by Week day - ie Mon, Tue etc

Hi 

 

I need to sum multple event hours which happen on a given day of the week during a set time period.

For instance, I want to see the sum of events hours over a month in columns Monday, Tuesday, through to Sunday. This is to see the supply or demand on a given day of the week.

 

How can I sum a these hours by week days?

 

Any ideas?

Matt

Just add a column to your data table, or to your Date table along these lines

 

Weekday = FORMAT(Dates[Date],"DDDD")

And then just drag that column to the axis of your visual.

Doesn't seem to work for DAX.  "Function 'FORMAT' is not allowed as part of calculated DAX expressions on DirectQuery models."


 

Expression.Error: The name 'FORMAT' wasn't recognized. Make sure it's spelled correctly.

Nope. Does not work. I just get this error over and over "Cannot find table 'Dates'."

In my case this did not work. To correct I removed the table reference:

Day of Week Short Name = FORMAT([Date],"DDD")
Output= Mon, Tue, Wed, etc. 

Brilliant! Yet simple

this does not work,  I copied and pasted get too many arguments

Or in Power Query:

 

#"Day of Week" = Table.AddColumn(#"__prior command name__", "__desired new column name__", each Date.DayOfWeekName([__column referencing__], "en-US"), type text)
in
#"Day of Week"

Hi

Is it possible to return short names of weekdays in Power Query?

(In DAX it is possible with FORMAT function)

This also works as part of the addcolumn query when building the Date Table.

For Example: 
Date =
ADDCOLUMNS (
CALENDAR (DATE(2000,1,1), DATE(2025,12,31)),
"Weekday", FORMAT([Date], "DDDD")
)

Excellent, thanks Phil
