Happy Birthday to Me! Happy birthday to Me!

Write a program that prints Happy birthday to me! on its birthday.


The program's birthday is the creation, last modification or compilation time of the program (you choose), and must not be hard-coded.
The date you use as the birthday must not be affected by the program's invocation or execution in any way. You can't modify your birthday.
For extra credit (-15% byte count), print Happy birthday to you! on your birthday (hard coded), if it doesn't coincide with the program's. Or use some celebrity's birthday and get -14%.
It must print only this, and not print anything on any other day. 
Count bytes, in UTF-8.
Use the Gregorian calendar.


Good luck and happy birthday (to the newborn programs).

P.S.
Following Izkata's comment, if you print Happy birthday to Mel on Mel Kaye's birthday, you get 20% off. But you have to provide a credible source that it's this date.
bash - 65

[ `date +%d%m -r $0` = `date +%d%m` ]&amp;&amp;echo Happy birthday to me!
