Obtaining Various Date Information from Date Information in SQL Server

Hello everyone,

In this article, I will try to give information about how to obtain various date information from date information in SQL Server.

You may want to see or use different variations of the date information you have in SQL Server.

You can use some of this information by using the code below.

DECLARE @Date DATE;
SET @Date = GETDATE()
SELECT @Date AS [Date],
       YEAR(@Date) * 10000 + MONTH(@Date) * 100 + DAY(@Date) AS [DateKey],
       DAY(@Date) AS [Day Number],
       DATENAME(DAY, @Date) AS [Day],
       CAST(DATEPART(dy, @Date) AS NVARCHAR(5)) AS [Day of Year],
       DATEPART(DAY, @Date) AS [Day of Year Number],
       DATENAME(WEEKDAY, @Date) AS [Day of Week],
       DATEPART(WEEKDAY, @Date) AS [Day of Week Number],
       DATENAME(WEEK, @Date) AS [Week of Year],
       DATENAME(MONTH, @Date) AS [Month],
       SUBSTRING(DATENAME(MONTH, @Date), 1, 3) AS [Short Month],
       N'Q' + DATENAME(QUARTER, @Date) AS [Quarter],
       N'H' + CASE
                  WHEN DATEPART(MONTH, @Date) < 7 THEN
                      N'1'
                  ELSE
                      N'2'
              END AS [Half of Year],
       CAST(DATENAME(YEAR, @Date) + N'-' + DATENAME(MONTH, @Date) + N'-01' AS DATE) AS [Beginning of Month],
       CASE
           WHEN MONTH(@Date)
                BETWEEN 1 AND 3 THEN
