Days of my Life
is a simple tool to see how old (in days) you are. The shown birthday when you leave the app will be stored in a tiny file on your mac and read when you fire up the app again. So you don't need to do one thing again and again.
There once was "superkaramba theme" for KDE I wrote. Since I haven't had Linux for some years now and switched to a Mac, I simply had to write this app.
This app is absolutely freeware but also out of any warranty.
