Answer 1

Well something to get your started unless someone posts a one-liner!

# Get the date in you want to start listing files from using your
# sample file. This will assign the variable in the format of MMDDYYYY
$ start=$(date -d "-5 days" '+%m%d%Y' < <(date -r /this/is/the/directory/file.txt))

# Get the date in you want to end listing files from. using your
# sample file. This will assign the variable in the format of MMDDYYYY
$ end=$(date -d "+5 days" '+%m%d%Y' < <(date -r /this/is/the/directory/file.txt))

# Create two temp files. touch -t will force the timestamp on
# these files to match the content of variables
$ touch -t "$start" /tmp/s$$
$ touch -t "$end" /tmp/e$$

# Use these temp files timestamp as a pivot mechanism by find commands
# newer option. This will list files whose timestamp is in between our 
# temp files timestamp which we captured from your sample file
$ find /path/to/files -type f -newer /tmp/s$$ -and -not -newer /tmp/e$$
