This expression  SELECT    DATEPART DW   my date var  - 1       DATEFIRST     7    will always return a number between 0 and 6 where  0 - gt  Sunday 1 - gt  Monday 2 - gt  Tuesday 3 - gt  Wednesday 4 - gt  Thursday 5 - gt  Friday 6 - gt  Saturday   Independently from   DATEFIRST  So a weekend day is tested like this  SELECT  CASE            WHEN    DATEPART DW   my date var  - 1       DATEFIRST     7  IN  0 6             THEN 1            ELSE 0        END  AS is weekend day

This will get you the name of the day   SELECT DATENAME weekday  GETDATE

DECLARE  dayNumber INT  SET  dayNumber   DATEPART DW  GETDATE      --Sunday   1  Saturday   7  IF  dayNumber   1 OR  dayNumber   7       PRINT  Weekend   ELSE     PRINT  NOT Weekend     This may generate wrong results  because the number produced by the weekday datepart depends on the value set by SET DATEFIRST  This sets the first day of the week   So another way is   DECLARE  dayName VARCHAR 9   SET  dayName   DATEName DW  GETDATE      IF  dayName    Saturday  OR  dayName    Sunday        PRINT  Weekend   ELSE     PRINT  NOT Weekend

Attention  The other answers only work on SQL Servers with English configuration  Use SET DATEFIRST 7 to ensure DATEPART DW       returns 1 for Sunday and 7 for Saturday   Here s a version that is independent of the local setting and does not require to use    CREATE FUNCTION  dbo   fct IsDateWeekend     date DATETIME   RETURNS BIT AS BEGIN     RETURN CASE WHEN DATEPART DW   date     DATEFIRST - 1   gt  5  THEN 1 ELSE 0 END  END    If you don t want to use the function  simply use this in your SELECT statement   CASE WHEN DATEPART DW  YourDateTime     DATEFIRST - 1   gt  5  THEN  Weekend  ELSE  Weekday  END

Many ways to do this  you can use DATENAME and check for the actual strings  Saturday  or  Sunday   SELECT DATENAME DW  GETDATE      Or use the day of the week and check for 1  Sunday  or 7  Saturday   SELECT DATEPART DW  GETDATE
