---Here is a version that gets the month end dates typically used for accounting purposes

DECLARE @StartDate datetime;
 DECLARE @EndDate datetime; 
 SET @StartDate = '2010-1-1'; 
 SET @EndDate = '2020-12-31';  
 --Procedure here:   





 WITH RecursiveRowGenerator (Row#, Iteration)                             
 AS (        SELECT 1, 1         
 UNION ALL        
 SELECT Row# + Iteration, Iteration * 2         
  FROM RecursiveRowGenerator         
  WHERE Iteration * 2 < CEILING(SQRT(DATEDIFF(MONTH, @StartDate, @EndDate)+1)) 
  UNION ALL        SELECT Row# + (Iteration * 2), Iteration * 2 
           FROM RecursiveRowGenerator         
           WHERE Iteration * 2 < CEILING(SQRT(DATEDIFF(MONTH, @StartDate, @EndDate)+1))      )  
               , SqrtNRows AS (        SELECT *          FROM RecursiveRowGenerator         
 UNION ALL        SELECT 0, 0      ) 
 SELECT TOP(DATEDIFF(MONTH, @StartDate, @EndDate)+1)         
           DateAdd(d,-1,DateAdd(m,1, DATEADD(month, DATEDIFF(month, 0, @StartDate) + A.Row# * POWER(2,CEILING(LOG(SQRT(DATEDIFF(MONTH, @StartDate, @EndDate)+1))/LOG(2))) + B.Row#, 0)  ))
Row#   FROM SqrtNRows A, SqrtNRows B  ORDER BY A.Row#, B.Row#;
