  select cust_id, cust_fname, cust_lname, cust_dob from birthdays
where cust_active = 1 and cust_dob > '1900-01-01 00:00:00.000'

  Looking to write a simple query that will return the Birthday's, by month if I choose a Date Range in the month spcified
  So this code (below) because I chose January, will ignore the year and day.
  select cust_id, cust_fname, cust_lname, cust_dob from birthdays
where cust_active = 1 and cust_dob between '1995-01-26 00:00:00.000' and '1995-01-27 00:00:00.000'

  So that query (should) will return all birthdays in the month of Jan, no matter the year or date.
  The obvious is the @MonthStart code above, I just dont know how to lay it out correctly.

  If finding rows by birth month without regard to year or day is something important, it's probably worthwhile to materialize the birth month in the table using a persisted computed column.  Like this....

  
 CREATE TABLE dbo.birthdays
        (
         cust_id    INTEGER         NOT NULL PRIMARY KEY
        ,cust_fname NVARCHAR(50)    NOT NULL
        ,cust_lname NVARCHAR(50)    NOT NULL
        ,cust_dob   DATETIME        NOT NULL
        ,cust_dobmo AS DATEPART(mm,cust_dob) PERSISTED --<----<<< Added this column    
        )
;


  Then the code become trivial for such things.  For example...

  
DECLARE @pSomeDate DATETIME = GETDATE(); --Could be a parameter for a Stored Procedure or iTVF

   SELECT *
     FROM dbo.birthdays
    WHERE cust_dobmo = DATEPART(mm,@pSomeDate)
  ;

  One way or another, that's going to guarantee at least one index scan and possibly 2 on the second bit of code even after you add "where conditions as per your requirement".

  Or take a step back and consider whether "dob" shouldn't be stored as separate columns to begin with, in accordance with standard data normalization (if you need to constantly look only at the month of a date, that might make it an atomic value, even though that's not normally true for most date columns). 

  Don't fall into the trap of trying to store data a certain way just because it's displayed a certain way.  Remember, you can always combine/reformat columns to display data as needed.

  The easiest way is probably to "fudge" a bit and store dob as a date but with a default year of 1900, and store the actual birth year in a separate column.  This makes checking the birth month (and day, if needed) very easy and standard, viz:
  cust_dob >= '19000101' AND cust_dob < '19000201'
  It also makes checking min age rather easy:
  --check if cust is at least 18 yo
  cust_yob <= '1998' OR (cust_yob = 1997 AND ...)

  Or you could store y&m&d separately, with of course a check constraint to verify that the values yielded a valid date.

  I'd rather store the date as a date and use computed columns if I need the month, day, or year separately on a regular basis.

  I don't know if computed columns still prevent parallel execution plans and/or still have other execution quirks. 

  But it doesn't really matter.  Either way, I'd still prefer to properly normalize data whenever possible, and for the standard reason: it prevents issues and more work later.  You can bet that sometime after you compute and store the month, they'll be a requirement to notify based on birthdays in the upcoming week, and you're back to adjusting the table yet again to add yet another computed column, day.

  I'd rather store the date as a date and use computed columns if I need the month, day, or year separately on a regular basis.

  I don't know if computed columns still prevent parallel execution plans and/or still have other execution quirks. 

  But it doesn't really matter.  Either way, I'd still prefer to properly normalize data whenever possible, and for the standard reason: it prevents issues and more work later.  You can bet that sometime after you compute and store the month, they'll be a requirement to notify based on birthdays in the upcoming week, and you're back to adjusting the table yet again to add yet another computed column, day.

  I think I covered that in my post, or am I imagining that I wrote month, day, or year?

  If you're going to store them all separately, then it's redundant to store them combined, and again violates normal form (redundant data).

  I'm not against computed columns per se, but I don't believe they are the proper solution for this problem.

  A date is a date and should be stored as a date. Just saying.
