Check if a date column is between 2 hard coded dates

[Jkrupski]

Hello,

I am very new to power bi and dax, learning as I go.

I am trying to use an if statement that checks a date added column and compares it to 2 hard coded dates, if it is between the dates I want to display "P3" and if not then display "NA" in a new column. I have this code:

columnTest =

VAR dateAdded = FORMAT(table[column], "m/d/yyyy")

VAR P3Start = FORMAT(DATE(2025,3,29), "m/d/yyyy")

VAR P3End = FORMAT(DATE(2025,3,29), "m/d/yyyy")

RETURN

If(dateAdded <= P3End && dateAdded >= P3Start, "P3",

 "NA")

One date that is checking is 3/4/25, but it is constantly giving me the NA result where I want it to give the P3 result.

Any help would be greatly appreciated!

Thank you!

Hi @Jkrupski ,

Thanks for the reply from Greg_Deckler .

There is something wrong with your start date and end date, they are both March 29, 2025, and P3 is returned only when the date is equal to March 29, 2025, and NA is returned for other dates.

Modify your syntax, something like the code below:

columnTest = 
VAR dateAdd = 'Table'[column]
VAR P3Start = DATE(2025, 3, 4)
VAR P3End   = DATE(2025, 3, 29)
RETURN
    IF(
         dateAdd>= P3Start && dateAdd <= P3End,
        "P3",
        "NA"
    )

The final visual effect is shown below:

@Jkrupski Try:

columnTest =
VAR dateAdded = [column]
VAR P3Start = DATE(2025,3,29)
VAR P3End = DATE(2025,3,29)
RETURN
If(dateAdded <= P3End && dateAdded >= P3Start, "P3",
 "NA")

FORMAT turns dates into text and that is not a good way to compare dates.
