Birthday Reminder For Gnome Panel

This program checks the file /home/rsrijith/shell/birthday_reminder.txt to find the upcoming birthdays in 20 days and writes into the file /home/rsrijith/shell/birthdays.
There is a file called /home/rsrijith/shell/birthdays1, the difference between it and birthdays file is that birthdays contains only first name of the person and birthdays1 contains the whole name.
So that's it. Now the code....

#!/bin/bash
echo "Birthday Finder ">>/home/rsrijith/logs/bday
date>>/home/rsrijith/logs/bday
tillm=$(date --date="+20 day" +"%b")
nowm=$(date +"%b")
tilld=$(date --date="+20 day" +"%2d")
nowd=$(date +"%d")
nowd=$((10#$nowd))
year=$(date +"%Y")
FileName='/home/rsrijith/shell/birthday_reminder.txt'
