## How to get a distinct count for each week and a weekly average of a distinct count

Hello!

I am having trouble figuring out how to sort my data by week. I have the received date and the project ID, but I am unsure how to calculate the week number.  My data consists of individual activities for the projects so I need to use a count of distinct project IDs.

I am trying to do 2 things:

• Create a visual of # projects received each week (line graph, bar graph, etc. with the disctinct count on the y axis and week on the x axis)
• Calculate the average number of projects received weekly (ex: what is the average number of projects received per week)

My data looks like this

 Activity ID Project ID Project Received Date a 1 2/1/2020 b 1 2/1/2020 c 1 2/1/2020 a 2 3/5/2021 a 3 4/1/2021 b 3 4/1/2021

The distinct count of projects is pretty straight forward:

``Projects =DISTINCTCOUNTT ( ProjectsTable[Project ID] )``

The AVG per week will require a calendar table with the year-week in it then you can use a measure like this.

``````Avg Weekly Projects = AVERAGEX(
VALUES(Dates[Year Week]),
[Projects]
)``````

I have attached my sample file for you to look at.  It also contains theDAXX code to make the calendar table.

Hi,

You should create a Calendar Table and in that write a calculated column formula using the WEEKNUM feature to extract the week number from the Date.
