Kwanzaa is a week-long holiday honoring African culture and traditions. It falls between December 26 and January 1 each year. Maulana Karenga, an African-American leader, proposed this observance and it was first celebrated between December 1966 and January 1967. It is celebrated by people from a range of African countries and their descendants. Kwanzaa consists of a week of celebrations, which ends with a feast and the exchange of gifts. During the celebrations, candles are lit and libations are poured. A libation is the name given to a ritual pouring of a drink as an offering to a god. During Kwanzaa, a wooden unity cup is used to pour the libations.
