The hardest part of this problem is the date arithmetic.  If the 
problem were to print all files modified between, say, 10 and 40 
days ago, the solution would be simple (I've tested this to some 
extent, but it's still more or less off the top of my head):

#!/bin/sh
# mbetween path bound_1 bound_2
# Argument 1 is taken to be the root of the directory tree to 
# search.  Argument 2 is one bound (in days), and argument 
# 3 is the other bound (in days).

find $1 -mtime -$2 -print > /tmp/mbetween.$$
find $1 -mtime -$3 -print >> /tmp/mbetween.$$

sort /tmp/mbetween.$$ > /tmp/mbetween2.$$
uniq -u /tmp/mbetween2.$$

rm -f /tmp/mbetween.$$ /tmp/mbetween2.$$
exit 0

If you had a date arithmetic package (didn't one just get posted
somewhere recently?) which supplied a Julian date function, you 
could provide a front end to mbetween (this is pseudocode):

#!/bin/sh
# better_mbetween path date_1 date_2

mbetween $1 `expr `jdate `date`` - `jdate $2`` \
            `expr `jdate `date`` - `jdate $3``
