Batch rename # of week

I want to rename a few files using batch.
I need it to look like DD.MM.YY - # week randomname,
so let's say 2.7.2013-27.week abcdefg.xls

So far I'm using

for /f "tokens=1-5 delims=/ " %%d in ("%date%") do (
  rename "C:\TEST\123.xlsx" %%e%%f%%g.xlsx
)

which comes up with DD.MM.YYYY and is perfect for the first part.
Can you help with the rest?

@echo off
for /F "tokens=1-5 delims=/" %%d in ("%date%") do (
   set ddmmyy=%%e.%%f.%%g
   set /A dd=1%%e-100, mm=1%%f-100, yy=%%g, yyM1=yy-1
)
rem Get Julian Day Number of today's date
if %mm% lss 3 set /A mm+=12, yy-=1
set /A a=yy/100, b=a/4, c=2-a+b, e=36525*(yy+4716)/100, f=306*(mm+1)/10, jdn=c+dd+e+f-1524
rem Subtract Julian Day Number of January/1st (get number of days in year)
set /A a=yyM1/100, b=a/4, c=2-a+b, e=36525*(yyM1+4716)/100, f=306*14/10, days=jdn-(c+1+e+f-1524)+1
rem Get number of week
set /A week=(days+3)/7+1
ECHO rename "C:\TEST\123.xlsx" "%ddmmyy% - %week%.week !random!!random!.xlsx"

Windows code for GNU awk:

awk "BEGIN {print strftime(\"%U\",mktime(\"YYYY MM DD hh mm ss\"))}"

Example:

>for /f %i in ('awk "BEGIN {print strftime(\"%U\",mktime(\"2013 07 03 12 00 00\"))}"') do @echo %i
26

This will give you dates, week of year, and you can use !random!!random! with delayed expansion to give you a random filename.

Here's an example script - year month day sorts properly in a folder if that matters to you.

@echo off
call datetime.bat /quiet
setlocal enabledelayedexpansion
for %%a in (*.xlsx) do (
  rename "%%a" "%year%.%month%.%day% - %woy%.week !random!!random!%%~xa"
)

Here is datetime.bat
