Calculate Number of days cell is Blank

[GMadd]

I need to calculate the number of days a cell has been blank (OTM #) based on the (Delivery Created On) date in my table and todays date. I am wanting to measure how long it takes a delivery to be assigned an OTM #. Once the OTM # is assigned I do not need a calculation. I just want to show "this delivery has been created on 3/25/2024 and it has been 2 days and still does not have an OTM#". 

Delivery	Delivery Created On	OTM #	Days Blank
11266	3/25/2024		2
11267	3/26/2024		1
11268	3/25/2024	125	0

Hi, @GMadd 

May I ask if you have solved this problem? Many thanks to @lbendlin for providing the correct way to calculate the date interval, but if you don not know what to do next, you can try the MEASURE below.

Measure:

Days Blank1 = 
VAR _day_diff =
    INT ( TODAY () - 1 / 6 - SELECTEDVALUE ( 'Table'[Delivery Created On] ) )
RETURN
    IF ( ISBLANK ( SELECTEDVALUE ( 'Table'[OTM #] ) ), _day_diff, 0 )
// Today is 4/1/2024

Thank you Yang

This worked the way I wanted it to.

INT(TODAY()-1/6-[Delivery Created On])

Please provide sample data that fully covers your issue.  Indicate the "current"  date for each row. Is it TODAY() ?
Please show the expected outcome based on the sample data you provided.

The current date for each row is the present day. Below is how I want it to work. In the Days Blank column I want a formula to calculate the number of days the OTM # cell has been blank based on the Delivery Created on column. The data below is assuming the current date is 3/27/2024. The first delivery was created on 3/25/2024 and I want the formula to count the number of days the delivery has been created for without an OTM number. This value should be 2 since there are two days from 3/25/2024 and the current date (3/27/2024).

Delivery	Delivery Created On	OTM #	Days Blank
11266	3/25/2024		2
11267	3/26/2024		1
11268	3/25/2024	125	0
11269	3/27/2024	126	0

which timezone?  Remember that the Power BI Service runs on UTC.

Eastern time zone

You would have to use TODAY() - 1/6  for that.

So what is the entire DAX formula to calculate the number of days the cell has been blank?
