I have a Date table and I want to create a calculated column that gives me the date of the previous year. For example, if the date is 2018 then Previous_Year column should be 2017.
Current Column is [_Year]
New Calculated Column is [Previous_Year]
In Dax this is what I have [Previous_Year]= DATE(YEAR([_Year]-1,YEAR))
thanks
Try something like this:
Previous_Year = YEAR('Datetable'[_Year])-1)
I am presuming that [_Year] holds a datevalue and that you want the year of that date minus 1.

I have a fact table which has 'Last Data Update' column that shows current month date(mm/dd/yyyy), 06/13/2022.
I am trying to add column called 'report month' that returns a value that shows previous month/year 05/2022 to create relationship with calendar table.
=Date.Month([Last Data Update])-1
I have used this code, but this only returns 5 and it is in number format.
is there a way to return 05/2022 in DAX ?
Thanks in advance.
This is M, not DAX. Replace your custom column with the following code:
Text.PadStart( Text.From(Date.Month([Last Data Update])-1),2,"0") &"/"& Text.From(Date.Year([Last Data Update]))
It worked for we with this 3 simple steps:
Step 1: Create a column with current year (True/False statement) by using:
CurrentYear = IF(YEAR([Last Data Update])=YEAR(NOW()),1,0)
Step 2: Create a column that will indicate if the current date (based on column "Last Data Update") belongs to previous month or not (True/False statement).
PreviousMonth = IF([CurrentYear]=1 && (MONTH(TODAY())-1)=MONTH([Last Data Update]),1,0)
Step 3: Create a filter on your visual where you select filter "PreviousMonth" with value "1" to show dates only from previous month).
If you like it. Don't forget to rate it.
Success,

This month-year
FORMAT( [Last Data Update], "mm/yyyy")
previous month
FORMAT( DATEADD([Last Data Update],-1,Month), "mm/yyyy")
My fiscal year start is in the past. I have a date column and I have the code below in a separate calculated column.
Year Start = DATE(YEAR(sales[close_date].[Year])-1,MONTH(12),DAY(22))
On the first row as an example, I have 31/07/2016 but in this column I am getting 21/01/1904
Could someone explain why?
You can check this below code-
Year Start = DATE(sales[close_date].[Year] -1, 12,22)
I have a column (monthyear) in the image below. I want to extract the Month and year from the column to put it in the new column. Note: In my dataset this information goes for every day of the year
So the new column would look like:
01/2020
01/2020
01/2020
etc.
In Power Query, use some of the date functions.
To get the year it will be
Date.Year([monthyear])
For the month, it will depend on how you want to format it. Using the month of June as an example:
To get 'Jun'
Date.ToText([monthyear],"MMM")
To get the month number in the format 06
Number.ToText(Date.Month([monthyear]), "00")
Just to get the number 6 it will be:
Date.Month([monthyear])
In DAX use the date functions
For year the calculated column will be:
YEAR([monthyear])
For the month:
MONTH([monthyear])
I would always do a much data transformation in Power Query when you can before it gets to the data model.
I have created two slicers in Power BI for Month and Year. These take the month and year value and in return generate a date.
Eg. Month - May & Year- 2019 generates 01/05/2019 with the help of the a measure formula :
MyFilterDate = DATE(SELECTEDVALUE(ListoY[Year]),SELECTEDVALUE(ListoM[Month],0),"01")
I want to subtract this date with one that is already in a column in the table.
I'm facing an issue when I try to subtract the measure from the existing column by writing DAX.
SUBVALNEW = DATEDIFF([MyFilterDate],Table[Date],DAY)
But when I try to do so, the result is not right. In fact when I try to check the value of [MyFilterDate] in the Data Model, it is not the same value as one calculated in the measure. (It instead looks like it displays the date in Table[Date])
Is there any way to subtract a Dynamically chosen date from a date in a column?
Any help would be appreciated.
I understand what your thinking patern is but power bi works a bit different. Dynamic measures cannot be used with calculated columns. When doing so the value of the measure is not set.
The way to go about this is by creating a Date table:
Date = CALENDAR(MIN(CalendarWeek[Date]);MAX(CalendarWeek[Date]))
Do NOT connect it to the model. From here you can make 2 slicers (based on the Date table). One your set to the month and the other to the year.
Next step is to adjust the MyFilterDate
MyFilterDate = DATE(SELECTEDVALUE('Date'[Date].[Year]);SELECTEDVALUE('Date'[Date].[MonthNo]);"01")
Make SUBVALNEW a measure (cannot be a column because it is dynamic!)
SUBVALNEW = DATEDIFF([MyFilterDate];SELECTEDVALUE(CalendarWeek[Date]) ;DAY)
Ass the Measuer to your visual, see end result below)
I have a date for when someone last bought something (lastbuy) and have an end date (lastday) column and I want to create a new column with this new value which will be a whole number. FYI, lastday and lastbuy are both Date/Time data types. I tried the following:
Column_name = DATEDIFF(lastday, lastbuy, day)
_______________________________________________
Column_name = COUNTX('Table_name', [lastday] - [lastbuy])
