Ghanaian name system
One of the reason why SpeedCalendar commissioner is interested in Calendar system is Ghanaian name system.
Commissioner had lived in Ghana for more than two years for national service therein. He has lots of Ghanaian friends, most of who have “day names” which corresponds to the day in the week when they were born. For example, Kwasi is one of Sunday-born-male’s name, and Ama is one of Saturday-born-female’s name. “Kofi” of Kofi Annan, former Secretary-General of US, corresponds to Friday-born-male.
While Commissioner lived in Ghana, he tried to guess Ghanaian friend’s names based on thier birthday, which had not succeeeded in. Now he may come up with Ghanaian friend’s name based on thier birthday, using SpeedCalendar technique! (Note that there are several names corresponds to each day of the week, so success rate is very low.)
