Help with script involving dates and days of week

[Salmon Trout]

usual rubbish

Why is he still here?

[Fields]

I think we  got it!

C:test>Display  mc.bat

@echo off
SET dwMONTH=%DATE:~4,2%
echo dwMONTH=%dwMONTH%
SET /A dwDAY=%DATE:~7,2%-16
echo dwDAY=%dwDAY%
SET dwYEAR=%DATE:~10,4%
echo dwYEAR=%dwYEAR%
if %dwday% LEQ 9 set dwday=0%dwday%
SET  Datenow=%dwyear%%dwmonth%%dwday%

QED

Post your complete code.

Im not sure about your other two questions?

When I back up against another month it fails also?

Can this be fixed?  Also can the day of the week that corresponds to the date be returned as a variable?

Day of week as a variable is already furnished:

Datenow is a variable.

Many suggestions from the Ghost and Helpless about what does not work.

But no suggestions or examples from the Ghost and Helpless of what can be done.

The Cat Bell?

better than giving wrong examples that cannot work, as you always did.
My help is always the same regarding dates. Either use vbscript or totally forget about batch. Use a real programming language.

 When I back up against another month it fails also.

The VBS/batch  works best for me.  Im still learning VBS.


C:test>display  backday.bat

@echo off
CScript //nologo  backday.vbs  > back.txt

set /p back=<back.txt
set back=%back:~0,9%


echo Back Date=%back%

echo From Now -35 days

Output:

C:test> backday.bat
Back Date=7/21/2010
From Now -35 days

C:test>Display   backday.vbs
Wscript.Echo Now -35

_________________________
The Date Now is:
 Wed 08/25/2010

 Also can the day of the week that corresponds to the date be returned as a variable?

The following will find the day of the week for Now -35 days. The -35 should be a command line argument. But Im new to VBS and do not know how to pass an argument from the command line to the vbs script. I shall find the answer.

C:test>display  day.bat

@echo off
rem Wscript.Echo WeekdayName(Weekday(Now -35))

cscript //nologo  day.vbs  > weekday.txt

set /p weekday=<weekday.txt

set weekday=%weekday:~0,3%

echo weekday=%weekday%

echo when Now -35 days

Output:

C:test>day.bat
weekday=Wed
when Now -35 days

C:test>

Perhaps this will help

Study the numerous scripts you steal from other posters (mainly me).

The ST examples are the worst of all.  The attempt by ST  is to make VBS more complicated than it is.  The VBS functions do all the work, we simply supply needed arguments. There are many good examples on the internet.

Find date last month and the weekday name with one script.


C:test>display  dayback.bat

@echo off
rem backday.vbs
rem Wscript.Echo Now -35
CScript //nologo  backday.vbs  > back.txt
set /p back=<back.txt
set back=%back:~0,9%

echo Back Date=%back%
echo From Now -35 days

rem Wscript.Echo WeekdayName(Weekday(Now -35))

cscript //nologo  day.vbs  > weekday.txt

set /p weekday=<weekday.txt

set weekday=%weekday:~0,3%

echo weekday=%weekday%

echo when Now -35 days

Output:

C:test>dayback.bat
Back Date=7/22/2010
From Now -35 days
weekday=Thu
when Now -35 days

I don't think anyone is reading this thread now, except for the masochists, and all your different login "names", Bill.

I dont think anyone is reading this thread now, except for the masochists, and all their different login names.

This is excellent thread with excellent solutions.

And all ST can say are his usual negative comments.

The batch/vbs will accept any date (forward or back ) as a command line argument for the batch.
Echo and redirect (>) modifies the vbs files.  The command line argument must include + or -


C:test>Display  forbac.bat

@echo off

echo Wscript.Echo Now %1  > backday.vbs
CScript //nologo  backday.vbs  > back.txt
set /p back=<back.txt
set back=%back:~0,9%

echo Now%1=%back%
echo From Now %1 days

echo Wscript.Echo WeekdayName(Weekday(Now %1)) > day.vbs

cscript //nologo  day.vbs  > weekday.txt

set /p weekday=<weekday.txt

set weekday=%weekday:~0,3%

echo weekday%1=%weekday%

echo From Now %1 days

Output:

C:test> forbac.bat  +130
Now+130=1/3/2011
From Now +130 days
weekday+130=Mon
From Now +130 days

Output:

C:test> forbac.bat  -130
Now-130=4/18/2010
From Now -130 days
weekday-130=Sun
From Now -130 days
