How do I get current date/time on the Windows command line in a suitable format for usage in a file/folder name?

See Windows Batch File (.bat) to get current date in MMDDYYYY format:

@echo off
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%c-%%a-%%b)
For /f "tokens=1-2 delims=/:" %%a in ('time /t') do (set mytime=%%a%%b)
echo %mydate%_%mytime%

If you prefer the time in 24 hour/military format, you can replace the second FOR line with this:

For /f "tokens=1-2 delims=/:" %%a in ("%TIME%") do (set mytime=%%a%%b)

C:> .\date.bat 2008-10-14_0642

If you want the date independently of the region day/month order, you can use "WMIC os GET LocalDateTime" as a source, since it's in ISO order:

@echo off
for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^>NUL`) do if '.%%i.'=='.LocalDateTime.' set ldt=%%j
set ldt=%ldt:~0,4%-%ldt:~4,2%-%ldt:~6,2% %ldt:~8,2%:%ldt:~10,2%:%ldt:~12,6%
echo Local date is [%ldt%]

C:>test.cmd Local date is [2012-06-19 10:23:47.048]

Two more ways that do not depend on the time settings (both taken from :How get data/time independent from localization:). And both also get the day of the week and none of them requires admin permissions!:

MAKECAB - will work on EVERY Windows system (fast, but creates a small temp file) (the foxidrive script): @echo off pushd "%temp%" makecab /D RptFileName=~.rpt /D InfFileName=~.inf /f nul >nul for /f "tokens=3-7" %%a in ('find /i "makecab"^<~.rpt') do ( set "current-date=%%e-%%b-%%c" set "current-time=%%d" set "weekday=%%a" ) del ~.* popd echo %weekday% %current-date% %current-time% pause More information about get-date function. ROBOCOPY - it's not native command for Windows XP and Windows Server 2003, but it can be downloaded from microsoft site. But is built-in in everything from Windows Vista and above: @echo off setlocal for /f "skip=8 tokens=2,3,4,5,6,7,8 delims=: " %%D in ('robocopy /l * \ \ /ns /nc /ndl /nfl /np /njh /XF * /XD *') do ( set "dow=%%D" set "month=%%E" set "day=%%F" set "HH=%%G" set "MM=%%H" set "SS=%%I" set "year=%%J" ) echo Day of the week: %dow% echo Day of the month : %day% echo Month : %month% echo hour : %HH% echo minutes : %MM% echo seconds : %SS% echo year : %year% endlocal And three more ways that uses other Windows script languages. They will give you more flexibility e.g. you can get week of the year, time in milliseconds and so on. JScript/batch hybrid (need to be saved as .bat). JScript is available on every system form NT and above, as a part of Windows Script Host (though can be disabled through the registry it's a rare case): @if (@X)==(@Y) @end /* ---Harmless hybrid line that begins a JScript comment @echo off cscript //E:JScript //nologo "%~f0" exit /b 0 *------------------------------------------------------------------------------*/ function GetCurrentDate() { // Today date time which will used to set as default date. var todayDate = new Date(); todayDate = todayDate.getFullYear() + "-" + ("0" + (todayDate.getMonth() + 1)).slice(-2) + "-" + ("0" + todayDate.getDate()).slice(-2) + " " + ("0" + todayDate.getHours()).slice(-2) + ":" + ("0" + todayDate.getMinutes()).slice(-2); return todayDate; } WScript.Echo(GetCurrentDate()); VSCRIPT/BATCH hybrid (Is it possible to embed and execute VBScript within a batch file without using a temporary file?) same case as JScript, but hybridization is not so perfect: :sub echo(str) :end sub echo off '>nul 2>&1|| copy /Y %windir%\System32\doskey.exe %windir%\System32\'.exe >nul '& echo current date: '& cscript /nologo /E:vbscript "%~f0" '& exit /b '0 = vbGeneralDate - Default.

It is installed by default on everything from Windows 7/Windows Server 2008 and above: C:\> powershell get-date -format "{dd-MMM-yyyy HH:mm}" To use it from a batch file: for /f "delims=" %%# in ('powershell get-date -format "{dd-MMM-yyyy HH:mm}"') do @set _date=%%# Self-compiled jscript.net/batch (never seen a Windows machine without .NET, so I think this is a pretty portable): @if (@X)==(@Y) @end /****** silent line that start JScript comment ****** @echo off :::::::::::::::::::::::::::::::::::: ::: Compile the script :::: :::::::::::::::::::::::::::::::::::: setlocal if exist "%~n0.exe" goto :skip_compilation set "frm=%SystemRoot%\Microsoft.NET\Framework\" :: Searching the latest installed .NET framework for /f "tokens=* delims=" %%v in ('dir /b /s /a:d /o:-n "%SystemRoot%\Microsoft.NET\Framework\v*"') do ( if exist "%%v\jsc.exe" ( rem :: the javascript.net compiler set "jsc=%%~dpsnfxv\jsc.exe" goto :break_loop ) ) echo jsc.exe not found && exit /b 0 :break_loop call %jsc% /nologo /out:"%~n0.exe" "%~dpsfnx0" :::::::::::::::::::::::::::::::::::: ::: End of compilation :::: :::::::::::::::::::::::::::::::::::: :skip_compilation "%~n0.exe" exit /b 0 ****** End of JScript comment ******/ import System; import System.IO; var dt=DateTime.Now; Console.WriteLine(dt.ToString("yyyy-MM-dd hh:mm:ss")); Logman This cannot get the year and day of the week. It's comparatively slow and also creates a temporary file and is based on the time stamps that logman puts on its log files. It will work on everything from Windows XP and above. It probably will be never used by anybody - including me - but is one more way... @echo off setlocal del /q /f %temp%\timestampfile_* Logman.exe stop ts-CPU 1>nul 2>&1 Logman.exe delete ts-CPU 1>nul 2>&1 Logman.exe create counter ts-CPU -sc 2 -v mmddhhmm -max 250 -c "\Processor(_Total)\%% Processor Time" -o %temp%\timestampfile_ >nul Logman.exe start ts-CPU 1>nul 2>&1 Logman.exe stop ts-CPU >nul 2>&1 Logman.exe delete ts-CPU >nul 2>&1 for /f "tokens=2 delims=_." %%t in ('dir /b %temp%\timestampfile_*^&del /q/f %temp%\timestampfile_*') do set timestamp=%%t echo %timestamp% echo MM: %timestamp:~0,2% echo dd: %timestamp:~2,2% echo hh: %timestamp:~4,2% echo mm: %timestamp:~6,2% endlocal exit /b 0 One more way with WMIC which also gives week of the year and the day of the week, but not the milliseconds (for milliseconds check foxidrive's answer): for /f %%# in ('wMIC Path Win32_LocalTime Get /Format:value') do @for /f %%@ in ("%%#") do @set %%@ echo %day% echo %DayOfWeek% echo %hour% echo %minute% echo %month% echo %quarter% echo %second% echo %weekinmonth% echo %year% Using TYPEPERF with some efforts to be fast and compatible with different language settings and as fast as possible: @echo off setlocal :: Check if Windows is Windows XP and use Windows XP valid counter for UDP performance ::if defined USERDOMAIN_roamingprofile (set "v=v4") else (set "v=") for /f "tokens=4 delims=.

Bear in mind that JavaScript's Date object properties involving month values are numbered from 0 to 11, not 1 to 12. So a value of 9 means October.

Regionally independent date time parsing

The output format of %DATE% and of the dir command is regionally dependent and thus neither robust nor smart. date.exe (part of UnxUtils) delivers any date and time information in any thinkable format. You may also extract the date/time information from any file with date.exe.

Examples: (in a cmd-script use %% instead of %)

date.exe +"%Y-%m-%d"
2009-12-22

date.exe +"%T"
18:55:03

date.exe +"%Y%m%d %H%M%S: Any text"
20091222 185503: Any text

date.exe +"Text: %y/%m/%d-any text-%H.%M"
Text: 09/12/22-any text-18.55

Command: date.exe +"%m-%d """%H %M %S """"
07-22 "18:55:03"`

The date/time information from a reference file:
date.exe -r c:\file.txt +"The timestamp of file.txt is: %Y-%m-%d %H:%M:%S"

Using it in a CMD script to get year, month, day, time information:

for /f "tokens=1,2,3,4,5,6* delims=," %%i in ('C:\Tools\etc\date.exe +"%%y,%%m,%%d,%%H,%%M,%%S"') do set yy=%%i& set mo=%%j& set dd=%%k& set hh=%%l& set mm=%%m& set ss=%%n

Using it in a CMD script to get a timestamp in any required format:

for /f "tokens=*" %%i in ('C:\Tools\etc\date.exe +"%%y-%%m-%%d %%H:%%M:%%S"') do set timestamp=%%i

Extracting the date/time information from any reference file.

for /f "tokens=1,2,3,4,5,6* delims=," %%i in ('C:\Tools\etc\date.exe -r file.txt +"%%y,%%m,%%d,%%H,%%M,%%S"') do set yy=%%i& set mo=%%j& set dd=%%k& set hh=%%l& set mm=%%m& set ss=%%n

Adding to a file its date/time information:

for /f "tokens=*" %%i in ('C:\Tools\etc\date.exe -r file.txt +"%%y-%%m-%%d.%%H%%M%%S"') do ren file.txt file.%%i.txt

date.exe is part of the free GNU tools which need no installation.

NOTE: Copying date.exe into any directory which is in the search path may cause other scripts to fail that use the Windows built-in date command.

Here's a variant from alt.msdos.batch.nt that works local-independently.

Put this in a text file, e.g. getDate.cmd

-----------8<------8<------------ snip -- snip ----------8<-------------
    :: Works on any NT/2k machine independent of regional date settings
    @ECHO off
    SETLOCAL ENABLEEXTENSIONS

    for /f "tokens=2-4 delims=(-)" %%a in ('echo:^|date') do (
      for /f "tokens=%toks% delims=.-/ " %%i in ('date/t') do (
        set '%%a'=%%i
        set '%%b'=%%j
        set '%%c'=%%k))
    if %'yy'% LSS 100 set 'yy'=20%'yy'%
    set Today=%'yy'%-%'mm'%-%'dd'% 
    ENDLOCAL & SET v_year=%'yy'%& SET v_month=%'mm'%& SET v_day=%'dd'%

    ECHO Today is Year: [%V_Year%] Month: [%V_Month%] Day: [%V_Day%]

    :EOF
-----------8<------8<------------ snip -- snip ----------8<-------------

To get the code to work sans error msg's to stderr, I had to add the single quotes arount the variable assignments for %%a, %%b and %%c. My locale (PT) was causing errors at one stage in the looping/parsing where stuff like "set =20" was getting executed. The quotes yield a token (albeit empty) for the left-hand side of the assignment statement.

The downside is the messy locale variable names: 'yy', 'mm' and 'dd'. But hey, who cares!

---

I use this (again not region independent (UK))

set bklog=%date:~6,4%-%date:~3,2%-%date:~0,2%_%time:~0,2%%time:~3,2%

---

The first four lines of this code will give you reliable YY DD MM YYYY HH Min Sec variables in Windows XP Professional and higher.

@echo off
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"

set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%" & set "fullstamp=%YYYY%-%MM%-%DD%_%HH%%Min%-%Sec%"
echo datestamp: "%datestamp%"
echo timestamp: "%timestamp%"
echo fullstamp: "%fullstamp%"
pause

---

Unfortunately this is not immune to regional settings, but it does what you want.

set hour=%time:~0,2%
if "%time:~0,1%"==" " set hour=0%time:~1,1%
set _my_datetime=%date:~10,4%-%date:~4,2%-%date:~7,2%_%hour%%time:~3,2%

Amazing the stuff you can find on Wikipedia.

---

Please use the following script to get the current day in the command line:

echo %Date:~0,3%day

---

"d:\Program Files\7-Zip\7z.exe" a -r code_%date:~10,4%-%date:~4,2%-%date:~7,2%.zip

---

Another way (credit):

@For /F "tokens=2,3,4 delims=/ " %%A in ('Date /t') do @( 
    Set Month=%%A
    Set Day=%%B
    Set Year=%%C
)

@echo DAY = %Day%
@echo Month = %Month%
@echo Year = %Year%

Note that both my answers here are still reliant on the order of the day and month as determined by regional settings - not sure how to work around that.

---

This isn't really briefer but might be a more flexible way (credit):

FOR /F "TOKENS=1* DELIMS= " %%A IN ('DATE/T') DO SET CDATE=%%B
FOR /F "TOKENS=1,2 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET mm=%%B
FOR /F "TOKENS=1,2 DELIMS=/ eol=/" %%A IN ('echo %CDATE%') DO SET dd=%%B
FOR /F "TOKENS=2,3 DELIMS=/ " %%A IN ('echo %CDATE%') DO SET yyyy=%%B
SET date=%mm%%dd%%yyyy%

Here's a way to get date time in a single line:

for /f "tokens=2,3,4,5,6 usebackq delims=:/ " %a in ('%date% %time%') do echo %c-%a-%b %d%e

In the US this will output "yyyy-mm-dd hhmm". Different regional settings will result in different %date% outputs, but you can modify the token order.

If you want a different format, modify the echo statement by rearranging the tokens or using different (or no) separators.

---

Just use this line:

PowerShell -Command "get-date"

Matthew Johnson's one-liner solution to get the one-liner date and time is eloquent and useful.

It does however need a simple modification to work from within a batch file:

for /f "tokens=2,3,4,5,6 usebackq delims=:/ " %%a in ('%date% %time%') do echo %%c-%%a-%%b %%d%%e

---

And here is a similar batch-file for the time portion.

I changed the answer with the batch file from vMax so it works with the Dutch language too.
The Dutch - persistent as we are - have a few changes in the %date%, date/t, and date that break the original batch-file.

It would be nice if some people can check this against other Windows locales as well, and report back the results.
If the batch-file fails at your location, then please include the output of these two statements on the command prompt:
echo:^|date
date/t

This is a sample of the output you should get from the batch-file:

C:\temp>set-date-cmd.bat
Today is Year: [2011] Month: [01] Day: [03]
20110103

Here is the revised code with comments on why:

:: https://stackoverflow.com/questions/203090/how-to-get-current-datetime-on-windows-command-line-in-a-suitable-format-for-usi
:: Works on any NT/2k machine independent of regional date settings
::
:: 20110103 - adapted by jeroen@pluimers.com for Dutch locale
:: Dutch will get jj as year from echo:^|date, so the '%%c' trick does not work as it will fill 'jj', but we want 'yy'
:: luckily, all countries seem to have year at the end: http://en.wikipedia.org/wiki/Calendar_date
::            set '%%c'=%%k
::            set 'yy'=%%k
::
:: In addition, date will display the current date before the input prompt using dashes
:: in Dutch, but using slashes in English, so there will be two occurances of the outer loop in Dutch
:: and one occurence in English.
:: This skips the first iteration:
::        if "%%a" GEQ "A"
::
:: echo:^|date
:: Huidige datum: ma 03-01-2011
:: Voer de nieuwe datum in: (dd-mm-jj)
:: The current date is: Mon 01/03/2011
:: Enter the new date: (mm-dd-yy)
::
:: date/t
:: ma 03-01-2011
:: Mon 01/03/2011
::
:: The assumption in this batch-file is that echo:^|date will return the date format
:: using either mm and dd or dd and mm in the first two valid tokens on the second line, and the year as the last token.
::
:: The outer loop will get the right tokens, the inner loop assigns the variables depending on the tokens.

A function that is based on wmic:

:Now  -- Gets the current date and time into separate variables
::    %~1: [out] Year
::    %~2: [out] Month
::    %~3: [out] Day
::    %~4: [out] Hour
::    %~5: [out] Minute
::    %~6: [out] Second
  setlocal
  for /f %%t in ('wmic os get LocalDateTime ^| findstr /b [0-9]') do set T=%%t
  endlocal & (
    if "%~1" neq "" set %~1=%T:~0,4%
    if "%~2" neq "" set %~2=%T:~4,2%
    if "%~3" neq "" set %~3=%T:~6,2%
    if "%~4" neq "" set %~4=%T:~8,2%
    if "%~5" neq "" set %~5=%T:~10,2%
    if "%~6" neq "" set %~6=%T:~12,2%
  )
goto:eof

Upside: Region independent. Downside: Only system administrators can run wmic.exe.

Usage:

call:Now Y M D H N S
echo %Y%-%M%-%D% %H%:%N%:%S%

This echos a string like this:

2014-01-22 12:51:53

Note that function parameters are out-Parameters - that is, you must supply variable names instead of values.

All parameters are optional, so call:Now Y M is a valid call if you only want to get year and month.

I had a similar problem. I have an automatic daily download from an FTP server of an encrypted file. I wanted to decrypt the file using gpg, rename the file to the current date (YYYYMMDD format) and drop the decrypted file into a folder for the correct department.

I went through several suggestions for renaming the file according to date and was having no luck until I stumbled upon this simple solution.

for /f "tokens=1-5 delims=/ " %%d in ("%date%") do rename "decrypted.txt" %%g-%%e-%%f.txt

It worked perfectly (i.e., the filename comes out as "2011-06-14.txt").

http://sourceforge.net/projects/unxutils/files/

Look inside the ZIP file for something called "Date.exe" and rename it "DateFormat.exe" (to avoid conflicts).

Put it in your Windows system32 folder.

It has a lot of "date output" options.

For help, use DateFormat.exe --h

I'm not sure how you would put its output into an environment variable... using SET.

Regional independent solution generating the ISO date format:

rem save the existing format definition
for /f "skip=2 tokens=3" %%a in ('reg query "HKCU\Control Panel\International" /v sShortDate') do set FORMAT=%%a
rem set ISO specific format definition
reg add "HKCU\Control Panel\International" /v sShortDate /t REG_SZ /f /d yyyy-MM-dd 1>nul:
rem query the date in the ISO specific format 
set ISODATE=%DATE%
rem restore previous format definition
reg add "HKCU\Control Panel\International" /v sShortDate /t REG_SZ /f /d %FORMAT% 1>nul:

What could still be optimized: Other processes might get confused if using the date format in the short period while it is modified. So parsing the output according to the existing format string could be 'safer' - but will be more complicated

---

Combine Powershell into a batch file and use the meta variables to assign each:

@echo off
for /f "tokens=1-6 delims=-" %%a in ('PowerShell -Command "& {Get-Date -format "yyyy-MM-dd-HH-mm-ss"}"') do (
    echo year: %%a
    echo month: %%b
    echo day: %%c
    echo hour: %%d
    echo minute: %%e
    echo second: %%f
)

You can also change the the format if you prefer name of the month MMM or MMMM and 12 hour to 24 hour formats hh or HH

I used date.exe, and renamed it to date_unxutils.exe to avoid conflicts.

Put it inside bin folder next to the batch script.

Code

:: Add binaries to temp path
IF EXIST bin SET PATH=%PATH%;bin

:: Create UTC Timestamp string in a custom format
:: Example: 20210128172058
set timestamp_command='date_unxutils.exe -u +"%%Y%%m%%d%%H%%M%%S"'
FOR /F %%i IN (%timestamp_command%) DO set timestamp=%%i
echo %timestamp%

PowerShell Try the code below. It will create the file or folder varible with the date as ddmmyyhhmm in 24hour time

[int] $day = Get-Date -UFormat %d
[int] $month = Get-Date -UFormat %m
[int] $year = Get-Date -UFormat %y
[String] $date = "$($day)$($month)$($year)"
$time = Get-Date -UFormat %R
$time -replace ‘[:]’,”"
$fileFolderName = $date + time

Given a known locality, for reference in functional form. The ECHOTIMESTAMP call shows how to get the timestamp into a variable (DTS in this example.)

@ECHO off

CALL :ECHOTIMESTAMP
GOTO END

:TIMESTAMP
SETLOCAL  EnableDelayedExpansion
    SET DATESTAMP=!DATE:~10,4!-!DATE:~4,2!-!DATE:~7,2!
    SET TIMESTAMP=!TIME:~0,2!-!TIME:~3,2!-!TIME:~6,2!
    SET DTS=!DATESTAMP: =0!-!TIMESTAMP: =0!
ENDLOCAL & SET "%~1=%DTS%"
GOTO :EOF

:ECHOTIMESTAMP
SETLOCAL
    CALL :TIMESTAMP DTS
    ECHO %DTS%
ENDLOCAL
GOTO :EOF

:END

EXIT /b 0

And saved to file, timestamp.bat, here's the output:

With Windows 7, this code works for me:

SET DATE=%date%
SET YEAR=%DATE:~0,4%
SET MONTH=%DATE:~5,2%
SET DAY=%DATE:~8,2%
ECHO %YEAR%
ECHO %MONTH%
ECHO %DAY%

SET DATE_FRM=%YEAR%-%MONTH%-%DAY% 
ECHO %DATE_FRM%

I know that there are numerous ways mentioned already. But here is my way to break it down to understand how it is done. Hopefully, it is helpful for someone who like step by step method.

:: Check your local date format
echo %date%

    :: Output is Mon 08/15/2016

:: get day (start index, number of characters)
::         (index starts with zero)
set myday=%DATE:~0,4%
echo %myday%
    :: output is Mon 

:: get month
set mymonth=%DATE:~4,2%
echo %mymonth%
    :: output is 08

:: get date 
set mydate=%DATE:~7,2% 
echo %mydate%
    :: output is 15

:: get year
set myyear=%DATE:~10,4%
echo %myyear%
    :: output is 2016

I note that the o/p did not ask for a region-independent solution. My solution is for the UK though.

This is the simplest possible solution, a 1-line solution, for use in a Batch file:

FOR /F "tokens=1-3 delims=/" %%A IN ("%date%") DO (SET today=%%C-%%B-%%A)
echo %today%
