Trying to advance time two weeks at a time

[Rain]

hello so i am new here and trying to create a batch that advancesa month every...20 seconds for example
i have this script which i was able to compile however to do what i want to do i have to keep changing the date manually on the script
set before=%date%
echo 04/06/2017 | date
ping localhost -n 15
echo %before% | date

so i am after a way to set it to repeat but change by a month at a time
as the way ive done it i have to change it myself instead of it doing this for example:

set before=%date%
echo 04/07/2017 | date
ping localhost -n 15
echo echo 04/08/2017 | date
ping localhost -n 15
echo echo 04/09/2017 | date

but i would be sitting here for some time writing out infinite dates
many thanks and any advice is welcome im new to scripting

You should avoid playing with date and time, because there may be unwanted side effects:
For example some virus scanners may notice the date modification of one month and handle it as "another month worked", so the (possibly paid) virus protection expires another month earlier (even if you restore the date).

Nevertheless, if you want to get the values (assuming your system is using the date format dd/mm/yy), then this might help you:

Code: Select all

:: get date format and values
for /f "tokens=1-3 delims=./-" %%a in ("%before%") do (
   set "day=%%~a"
   set "month=%%~b"
   set "year=%%~c"
)

:: remove trailing zeroes and inc month value
set "day=%day:*0=%"
set "month=%month:*0=%"

You then can change the values using "set /a" for example.
