Answer 3

the code must be running at least at regular interval or forever (by running it as daemon), better to launch it automatically at least at computer start...

to warn user, the simplest way would be to launch a new process wich execute another script wich will display the information (using GUI output) when a new birthday occurs, maybe with the possibility to recall it after some time and/or to disable repeating the same birthday(s) information ;)
