Adding column when Date is more than 21 days old

[Anonymous]

Hello.    I have a table names Contacts, and I would like to add a new column based upon the values of two other columns.   

If the column "Created Date" is older than 21 days from Today,  the new column should populate with "Expired".  If the column "Created Date" is not older than 21 days,  it should return the current value in the Status column.      

I have tried  IF ([CreatedDate] < TODAY() -21 Then "Expired" ELSE [Status])  and IF ([CreatedDate] < TODAY() -21, "Expired", [Status])

Any ideas?  

Thanks in advance.

@Anonymous , what was wrong with your second try?

cln =
IF ( [CreatedDate] < TODAY () - 21, "Expired", [Status] )

@Anonymous , oh, you need it in PQ. I've provided the DAX. PQ:

if [CreatedDate] < Date.AddDays(DateTime.Date( DateTime.LocalNow()), -21) then "Expired" else [Status]

I'd personally make a datediff calculated column with your data table, then use a Switch with case when datediff < 21 then 'Current Table'[status] else 'Expired'.

You'll need to work out the proper syntax, but you get the idea
