Lets face it, its great to celebrate your birthday, and you "pretend" its great to celebrate your friend, or significant others birthday. Bothday takes the "pretend" out of the celebration by calculating a date that is both of your birthdays.
The Bothday calculation uses ancient methods for combining dates, including various zodiacs from around the world, even secrets of Iceland, and Celtic history.
This program calculates and tracks Bothdays. It even gives you the ability to calculate a Bothday with a fellow iPhone owner close by, if you both tap the tune "Happy Bothday to Us" on your iPhone.
Bothday will also let you choose from different activities and places you might want to celebrate your Bothday. An email will be sent with your matched selections.
