TI-84 Program code to TI-89 Program code

[TICalcFreak08]

Hello. This is my first time on here, so... bear with me. However, I'd like to learn how to convert the following TI-83/TI-84+/SE program code (but it has to have an internal clock in order for it to work!), so... here is the (assume) TI-84+SE program code:

:"Life Odometer"
ClrHome
Normal
For(X,ú8,ú3)
Output(úX,2,"Alex Litzau's
If Xøú8:Output(úX+1,2,")
For(A,1,ý^(2))
End
End
Output(5,2,"Life Odometer")
For(A,1,ý^(3))
End
getKey
Output(8,2,"Press any key")
Repeat getKey
End
Lbl 5
ClrHome
Output(1,2,"Your Birthday")

int(abs(DüD
int(abs(EüE
If A<1 or A>12 or B<1 or B>31 or C<50 or C>99 or D>23 or E>59:Goto 5
A+B/100+C/ý^(4)üA

(Warning: Use the appropriate TI calculator font on your computer in order to view it; such an example would be TI83pc.ttf (or whatever that is). Is there a way I can convert this program (made by someone else, NOT me) and change everything to the appropriate TI-89 (BASIC only!) code? Thank you very much! I will give this program credit to the original person who made this program.
