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

Question

Update: Now that it's 2016 I'd use PowerShell for this unless there's a really compelling backwards-compatible reason for it, particularly because of the regional settings issue with using date. See @npocmaka's https://stackoverflow.com/a/19799236/8479

What's a Windows command line statement(s) I can use to get the current datetime in a format that I can put into a filename?

I want to have a .bat file that zips up a directory into an archive with the current date and time as part of the name, for example, Code_2008-10-14_2257.zip. Is there any easy way I can do this, independent of the regional settings of the machine?

I don't really mind about the date format, ideally it'd be yyyy-mm-dd, but anything simple is fine.

So far I've got this, which on my machine gives me Tue_10_14_2008_230050_91:

rem Get the datetime in a format that can go in a filename. set _my_datetime=%date%_%time% set _my_datetime=%_my_datetime: =_% set _my_datetime=%_my_datetime::=% set _my_datetime=%_my_datetime:/=_% set _my_datetime=%_my_datetime:.=_%  rem Now use the timestamp by in a new ZIP file name. "d:\Program Files\7-Zip\7z.exe" a -r Code_%_my_datetime%.zip Code 

I can live with this, but it seems a bit clunky. Ideally it'd be briefer and have the format mentioned earlier.

I'm using Windows Server 2003 and Windows XP Professional. I don't want to install additional utilities to achieve this (although I realise there are some that will do nice date formatting).

Answer 1

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]

Answer 2

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!:

1. 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.

2. 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.

3. 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()); 

4. 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. Returns date: mm/dd/yy and time if specified: hh:mm:ss PM/AM. '1 = vbLongDate - Returns date: weekday, monthname, year '2 = vbShortDate - Returns date: mm/dd/yy '3 = vbLongTime - Returns time: hh:mm:ss PM/AM '4 = vbShortTime - Return time: hh:mm  WScript.echo  Replace(FormatDateTime(Date,1),", ","-") 

5. PowerShell - can be installed on every machine that has .NET - download from Microsoft (v1, v2, v3 (only for Windows 7 and above)). 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=%%# 

6. 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")); 

7. 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 

8. 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% 

9. 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=. " %%# in ('ver') do if %%# GTR 5 (set "v=v4") else ("v=") set "mon=" for /f "skip=2 delims=," %%# in ('typeperf "\UDP%v%\*" -si 0 -sc 1') do (    if not defined mon (       for /f "tokens=1-7 delims=.:/ " %%a in (%%#) do (         set mon=%%a         set date=%%b         set year=%%c         set hour=%%d         set minute=%%e         set sec=%%f         set ms=%%g       )    ) ) echo %year%.%mon%.%date% echo %hour%:%minute%:%sec%.%ms% endlocal 

10. MSHTA allows calling JavaScript methods similar to the JScript method demonstrated in #3 above. 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.

    <!-- : Batch portion  @echo off setlocal  for /f "delims=" %%I in ('mshta "%~f0"') do set "now.%%~I"  rem Display all variables beginning with "now." set now.  goto :EOF  end batch / begin HTA -->  <script>     resizeTo(0,0)     var fso = new ActiveXObject('Scripting.FileSystemObject').GetStandardStream(1),         now = new Date(),         props=['getDate','getDay','getFullYear','getHours','getMilliseconds','getMinutes',             'getMonth','getSeconds','getTime','getTimezoneOffset','getUTCDate','getUTCDay',             'getUTCFullYear','getUTCHours','getUTCMilliseconds','getUTCMinutes','getUTCMonth',             'getUTCSeconds','getYear','toDateString','toGMTString','toLocaleDateString',             'toLocaleTimeString','toString','toTimeString','toUTCString','valueOf'],         output = [];      for (var i in props) {output.push(props[i] + '()=' + now[props[i]]())}     close(fso.Write(output.join('\n'))); </script>
