I need to do the following:
1) find files in certain directories that have todays date stamp
2) use these files as input arguements into another command

Use the touch command with the -t flag to touch a file with the date you need to search FROM, then use the find command with the -newer argument to locate files which are newer than the file you touched.

You can enter the files found into a variable this:

FILES=`find . -type f -newer [touched_file] {} \;

Then use the files in that variable one by in a for loop that holds whatever command you wish to operate on them

i.e.

for x in $FILES
do
[command(s)]
done

Regards.
