Kwanzaa celebrates what its founder, Maulana Karenga called the seven principles of Kwanzaa, or Nguzo Saba (originally Nguzu Saba – the seven principles of African Heritage), which Karenga said "is a communitarian African philosophy," consisting of what Karenga called "the best of African thought and practice in constant exchange with the world." They were developed in 1965, a year before Kwanzaa itself. These seven principles comprise Kawaida, a Swahili word meaning "common". Each of the seven days of Kwanzaa is dedicated to one of the seven.
On this, the sixth day of Kwanzaa the days principle is Kuumba.
Kuumba (Creativity): To do always as much as we can, in the way we can, in order to leave our community more beautiful and beneficial than we inherited it.
Kwanzaa is a secular festival observed by many African Americans from December 26 to January 1 as a celebration of their cultural heritage and traditional values.
