Inspired by memories of fantastic family birthday parties, mother-and-daughter team Nikki Tate and Dani Tate-Stratton researched the history of birthdays in order to answer such questions as, How much does where you grow up influence the way you celebrate getting a year older? Have people always celebrated birthdays? The more they investigated, the more they realized that there's a lot more to birthdays than cake, presents, a few games and perhaps a goody bag. They discovered there are as many ways to observe birthdays as there are places in which to do it.
