Date and Time Conversions Using SQL Server

By:   |   Updated: 2022-12-08   |   Comments (61)   |   Related: 1 | 2 | 3 | 4 | 5 | 6 | More > Dates


There are many instances when dates and times don't show up at your doorstep in the format you'd like it to be, nor does the output of a query fit the needs of the people viewing it. One option is to format the data in the application itself. Another option is to use the built-in functions SQL Server provides to format the date string for you.


SQL Server provides a number of options you can use for formatting a date/time string in SQL queries and stored procedures either from an input file (Excel, CSV, etc.) or a date column (datetime, datetime2, smalldatetime, etc.) from a table. One of the first considerations is the actual date/time value needed. The most common is the current date/time using getdate(). This provides the current date and time according to the server providing the date and time. If a universal date/time (UTC) is needed, then getutcdate() should be used. To change the format of the date, you convert the requested date to a string and specify the format number corresponding to the format needed.

How to get different date formats in SQL Server

  1. Use the SELECT statement with CONVERT function and date format option for the date values needed
  2. To get YYYY-MM-DD use this T-SQL syntax SELECT CONVERT(varchar, getdate(), 23)
  3. To get MM/DD/YY use this T-SQL syntax SELECT CONVERT(varchar, getdate(), 1)
  4. Check out the chart to get a list of all format options

Below is a list of SQL date formats and an example of the output.  The date used for all of these examples is "2022-12-30 00:38:54.840".

Format # Query Format Sample
1 select convert(varchar, getdate(), 1) mm/dd/yy 12/30/22

131 select convert(nvarchar, getdate(), 131) dd mmm yyyy hh:mi:ss:nnn AM/PM 10/12/1444 12:38:54:840AM

You can also format the date or time without dividing characters, as well as concatenate the date and time string:

Sample statement Format Output
select replace(convert(varchar, getdate(),101),'/','') mmddyyyy 12302022
select replace(convert(varchar, getdate(),101),'/','') + replace(convert(varchar, getdate(),108),':','') mmddyyyyhhmmss 12302022004426

If you want to get a list of all valid date and time formats, you could use the code below and change the @date to GETDATE() or any other date you want to use.  This will output just the valid formats.

DECLARE @counter INT = 0
DECLARE @date DATETIME = '2006-12-30 00:38:54.840'

CREATE TABLE #dateFormats (dateFormatOption int, dateOutput nvarchar(40))

WHILE (@counter <= 150 )
      INSERT INTO #dateFormats
      SELECT CONVERT(nvarchar, @counter), CONVERT(nvarchar,@date, @counter) 
      SET @counter = @counter + 1
      SET @counter = @counter + 1
      IF @counter >= 150

SELECT * FROM #dateFormats

Hi Osman,

You could just do UPDATE statements to convert your text values to the standard time values you mentioned. Another option is to use a CASE statement to make the change if you don't want to change the actual data.


Monday, September 12, 2022 - 6:29:56 PM - Osman Back To Top (90467)

Please help me with this..

I got a really messy data that I am trying to clean. There is a column there that has time. Most of the time values are entered in this format 18h00, which is fine. But there are rows that have “morning” or “afternoon” or “after dark” instead of actual time.

My question is: how do I convert these strings like “afternoon” which I know could be like “13h00” or something to a time value instead of having it as a string.

Hi Krishna,

try this.

select CONVERT(varchar(25),cast(@d as datetime),105)

I want to convert a Text Field which is saving the Data in String into a Date field. The value stored is in the below format.

Value Stored = 66028
Actual Value (or) Desired Output = 10-11-2021 (dd-mm-yyyy)

Hi Amol,

you could create another table with the mapping and then join to that table based on the day of the month to return your A, B, C, etc. values.


Saturday, September 18, 2021 - 1:32:31 PM - Amol Back To Top (89240)
i am beginner in sql
i have one task of conversion of date like.
if day of month is 01 then conversion would like A, like for 02 it would be B( 01= A,02=B,.......27=AA,28=AB...)

could we do like code this sql please suggest solution if it could be done.

Example #3 st the top of the article is wrong. You indicate that YYYY will be returned by format value 1. But this format only returns YY, as you indicate in the chart immediately below. 101 returns the year with century.

Friday, April 3, 2020 - 9:43:20 AM - Jeff Moden Back To Top (85264)

Be advised that the FORMAT function is horrible for performance.  It takes a very typical 43 times longer than even some of the more complex things you can do with CONVERT.  I STRONGLY RECOMMEND AVOIDING THE USE OF THE FORMAT FUNCTION FOR THAT REASON.  It's the "death of a thousand small cuts".

Tuesday, March 17, 2020 - 3:42:44 PM - Greg Robidoux Back To Top (85131)

Hi George, you can do this with the format function as well.  Here is a tip about that:

Also, I have heard that the format function is a lot slower than the convert function.


Tuesday, March 17, 2020 - 3:13:22 PM - George Back To Top (85130)

Wouldn't most of this be moot with the FORMAT function?  That will automatically turn it into an NVARCHAR(4000) field, and you have a lot of flexibility to define it how you want.

    format(getdate(), 'yyyy-MM-dd hh:mm:ss') AS [today],
    format(getdate(), 'yyyy-MM-dd')          AS [today2]

Monday, December 16, 2019 - 9:54:34 AM - Greg Robidoux Back To Top (83436)

Thanks Gregg for the feedback.  We will see if we can update all of the examples.

The reader could also run the T-SQL script and enter other dates.  This will produce all valid results, so they can see how the date would be formatted.


Saturday, December 14, 2019 - 11:27:03 AM - Gregg Tracton Back To Top (83426)

revise your example date, please.  use a example date (ex, 1/2/1994) that has a month AND day less than 10 so readers can see if the leading zero is prefixed or not.

Monday, June 3, 2019 - 11:55:28 AM - Anne Cao Back To Top (81310)

Thank you for the good tip.

I also see sometimes the column could store seconds only. The seconds is the seconds since 0 hours of the day.

Any conversion formula?


Thursday, May 16, 2019 - 11:00:26 AM - Greg Robidoux Back To Top (80105)

Thanks Stewart for the input.

As you mentioned this tip uses VARCHAR and that could be changed to NVARCHAR which will return the same results for most of the items and take care of format 130.


Thursday, May 16, 2019 - 10:49:18 AM - Stewart Back To Top (80104)

Formats 130 and 131 are the Islamic calendar date.  But 130 contains Arabic characters, and therefore you would need to convert to nvarchar, not varchar.  Still, the order of the parts comes out in a bit of a muddle, unless I tell my software to render it right-to-left.

Thursday, April 18, 2019 - 4:57:37 PM - Greg Robidoux Back To Top (79597)

Hi Ben,

you can do this: 

SELECT CONVERT(datetime,'1/1/2018 12:00:00 AM')



Thursday, April 18, 2019 - 3:19:51 PM - Ben LaRoche Back To Top (79596)

Does anyone know how to convert this format "1/1/2018 12:00:00 AM" (currently in text) to a date time type?

 any suggestion please ?

Thank you

Thursday, March 22, 2018 - 2:14:35 PM - Aubrey Back To Top (75502)


 A simpler way to format the date is:  



This will produce a date in this format: 2018-03-22

You can replace the “GETDATE()” with the name of date column you want to modify.


As for the Time, use:

SELECT FORMAT(GETDATE(), ‘hh:mm’) AS ‘ColumnName’

This will produce the time in this format: 01:07

Or, if you want the time returned in Military format, change the ‘hh’ to upper case ‘HH’


This will produce the time in this format: 13:09

Hope this helps someone.

 I would add that cast(date_expression as date) is sometimes a useful solution. It keeps the date characteristics for sorting, comparing, etc. but drops the time portion. This is great for items going to excel.

Hi there,

I am retrieving data with SQL from a Oracle database where I encounter different date formats in the same data group.

I run the SQL query in VBA and the query results are pasted in an excel tab. So in the same data column I have data with multiple date formats in excel.

Only one date format recognized as date, according to pc's regional settings. I need to convert all data into same format before I retrieve them to excel.

right now I use this: TO_CHAR(v.BASLANGICTARIHI, 'DD/MM/YYYY') but it does not help.

Can someone help me here?

Hi San,

use this select replace(convert(varchar, getdate(),103),'/','')  to get the output you need and then use one of these functions to add the space between each number

Would this work for you?

convert(varchar,getdate(),105) + ' ' + convert(varchar,getdate(),108)

Is there any reason you would not use this format:

9 or 109 select convert(varchar, getdate(), 9) Dec 30 2006 12:38:54:840AM

Actually, I was simply complimenting the "tip" as it provided exactly what I needed for ANY date:

 select replace(convert(varchar, getdate(),101),'/','') + replace(convert(varchar, getdate(),108),':','')

This converts any MSSQL datetime to MMDDYYYYHHMMSS - exactly what the Oracle folks wanted!


Thanks anyway :-)
