linux script help with dates

I have a script that I have to input a date into manually in the format of '20120915'. I only need to work with the dates from '20120815' to 20121001'. Could someone help me put some code together that could automatically insert these dates into a variable one by one into my script?
Maybe a for loop would work in this case?

Here is the script I am working with:

#!/bin/bash
UTIL=/cygdrive/c/apps/dcm4che-2.0.25-bin/bin
INPUT=/cygdrive/c/projects/fill/comb
BASEDIR=/cygdrive/c/projects/fill
$UTIL/dcmqr RADARCH4@10.10.51.32:104 -rStudyInstanceUID -qStudyDate=20120915 | grep "(0020,000D) UI #[0-9]*" | sed s/'(0020,000D) UI #[0-9]* \['// | sed s/'\] Study Instance UID'// | sed s/'] Study Instance'// | sed s/'UI'// | sed s/'U'// > $BASEDIR/A4_SUID
$UTIL/dcmqr RADARCH2@10.10.50.51:104 -rStudyInstanceUID -qStudyDate=20120915 | grep "(0020,000D) UI #[0-9]*" | sed s/'(0020,000D) UI #[0-9]* \['// | sed s/'\] Study Instance UID'// | sed s/'] Study Instance'// | sed s/'UI'// | sed s/'U'// > $BASEDIR/A2_SUID
comm -2 -3 <(sort $BASEDIR/A4_SUID) <(sort $BASEDIR/A2_SUID) > $BASEDIR/comb
count=0
exec 3<&0 #Save stdin to file descriptor 3.
exec 0<$INPUT # Redirect standar input.
while read line
do
input1=$(echo $line | awk '{ print $1 }')
echo "Sending :" ${input1}
$UTIL/dcmqr RADARCH4@10.10.51.32:104 -q0020000D=${input1} -cmove RADARCH2
count=$( expr $count + 1 ) 
done
exec 0<$3 #restore old stdin.
echo "Counter:" $count # Show deleted items

The areas where the dates get inserted are

-qStudyDate=20120915

-- awesome - thanks for great help on this. If I insert the above code into my script as below, would it just run until it hit the 'end date'?

#!/bin/bash
UTIL=/cygdrive/c/apps/dcm4che-2.0.25-bin/bin
INPUT=/cygdrive/c/projects/fill/comb
BASEDIR=/cygdrive/c/projects/fill
start="20120815"
end="20121001"
DATES=""
for i in $(seq 0 9999)
 do
  new=$(date -d "$start + $i days" "+%Y%m%d")
  if [[ $new -le $end ]]; then DATES=$DATES $new"; else break; fi
done
for D in $DATES
 do
  $UTIL/dcmqr RADARCH4@10.10.51.32:104 -rStudyInstanceUID -qStudyDate=$D | grep "(0020,000D) UI #[0-9]*" | sed s/'(0020,000D) UI #[0-9]* \['// | sed s/'\] Study Instance UID'// | sed s/'] Study Instance'// | sed s/'UI'// | sed s/'U'// > $BASEDIR/A4_SUID
  $UTIL/dcmqr RADARCH2@10.10.50.51:104 -rStudyInstanceUID -qStudyDate=$D | grep "(0020,000D) UI #[0-9]*" | sed s/'(0020,000D) UI #[0-9]* \['// | sed s/'\] Study Instance UID'// | sed s/'] Study Instance'// | sed s/'UI'// | sed s/'U'// > $BASEDIR/A2_SUID
 done
comm -2 -3 <(sort $BASEDIR/A4_SUID) <(sort $BASEDIR/A2_SUID) > $BASEDIR/comb
count=0
exec 3<&0 #Save stdin to file descriptor 3.
exec 0<$INPUT # Redirect standar input.
while read line
 do
  input1=$(echo $line | awk '{ print $1 }')
  echo "Sending :" ${input1}
  $UTIL/dcmqr RADARCH4@10.10.51.32:104 -q0020000D=${input1} -cmove RADARCH2
  count=$( expr $count + 1 ) 
 done
exec 0<$3 #restore old stdin.
echo "Counter:" $count # Show deleted items

Yes, that is the way I was wanting the script to behave, that is for the script to process only one day at a time. I just wasn't sure where to place the "done", but I have tested it out and it works as I had hoped.

thanks for all of the help- you're very knowledgeable.
