Create column with true/false for previous month

Hello,

I have a column with dates in the following format:

 

d/m/yyyy

 

How can I create a calculated column that has as values true for every entry that is on the previous month and false for the rest?

 

I tried the following but it didn't work.

 

 

=IF([Date]=EDATE(DATE(YEAR(NOW());MONTH(NOW()));-1);TRUE();FALSE())

 

I know I must be close but how can I implement the day to my formula?

@mork This should work...

 

Column =
IF ( YEAR ( Calendar[Date] ) = YEAR ( NOW () )
        && MONTH ( Calendar[Date] ) = MONTH ( NOW () ) - 1,
    TRUE (),
    FALSE ()
)

Hi Mork,

 

This should do the trick:

 

=IF(STARTOFMONTH(YourTable[YourDateField]) = date(year(TODAY()); MONTH(today())-1; 1) ;TRUE();FALSE())

 

HTH,

@mork This should work for you however in your dateColumn you will only need date that is not greater than today. 

 

NewColumn = IF( DATEDIFF('YOURTABLE'[dateColumn],TODAY(),DAY) <= 30, "Yes", "No")

@ankitpatira

Unfortunately that's is not what I want. Your formula is about the previous 30 days and not about the previous month. So for example today is the 13th of May. The data that I will see won't be the data of the previous month but will be the data of the last 30 days. Meaning half of April and half of May.
