Date Intervals

I posted a question on date intervals about a month back asking about how I could be able to go about a user entering the starting year/month/day and an ending year/month/day and then the script automatically cycling through each day of each month of each year that the user has specified.

I checked out Perderabo's datecalc script and it was helpful but still not exactly what I needed.

I've thrown together some code today but I know that it's not going to work, I just need some suggestions on how I can complete this.

Code:

#!/bin/ksh

#                     Ja Fe Ma Ap My Jn Jl Au Se Oc No De
set -A DaysInMonth xx 31 28 31 30 31 30 31 31 30 31 30 31

isLeapYr=`date.isLeapYr.ksh`
if (( isLeapYr==1 )); then
    DaysInMonth[2]=29
fi

while (( start_date_Y < end_date_Y )); do

    while (( start_date_m < end_date_m )); do

        while (( start_date_d < ${DaysInMonth[${start_date_d}]} )); do
        (( start_date_d=start_date_d+1 ))
        done

        (( start_date_m=start_date_m+1 ))
    done

    (( start_date_Y=start_date_Y+1 ))
done

Some of my concerns are:
Take a look at the start_date_m < end_date_m loop (the 2nd while loop). What if the starting month is 4 and the ending month is 10 (but the user meant the 10 month of the 2nd year) then the loop will break prematurely.

How do I adjust for this?

I'm continuuing to work on this script, so I will keep this post updated.
