Using Seq As A Variable With Padded Digits

Hi all. Im trying to use a sequence in a while loop like this below. I need it for navigating a year, month, day folder structure where a user can input the start date and have it go to the desired end date. The script will grab a certain file on each day then move onto the next. Ive got all that worked out using a static set of years in a for loop rather then a while loop with a seq. The problem is when I run into the month andn day folders as they are 01 02 03..10 11. Using the + 1 method it wont cd to the folders below 10 because the var is 1 2 3 instead of 01 02 03. Is there a way to make it add the zero to values below 10 but still keep count?

Code:

startdate=1
enddate=12
a=$startdate
if [ $a -lt 10 ]
   then a=0$a
   fi
 
while [ $a -lt $enddate ]
   DO OTHER THINGS HERE
   startdate=`expr $startdate + 1`
   a=$startdate
if [ $a -lt 10 ]
   then a=0$a
   fi
   done

       ple,  Britain  converted in 1752, The USSR in 1918 and Greece in 1923. Most European countries used the Julian calendar prior to the Grego-
       rian.

PARAMETERS

		- The month as a number from 1 (for January) to 12 (for December)

	      o $day
