The one finding the item in their portion is elected king or have to pay forward to the other later (depending on the region).
Kwanzaa is not a religious holiday but rather a cultural celebration among African-Americans and it takes place between December 26 and January 1st of each year. It started in the year 1966, among the civil rights movement in the US, as a way to unite and celebrate the differences of the African-American population. Each day of that week is dedicated to a theme, like: unity, self-determination, collective work and responsibility, cooperative economics, purpose, creativity and faith. It's celebrated with family members and friends, with music and reflections on the theme of the day.
Hanukkah is a religious Jewish celebration, that takes place somewhere between late November and late December each year, in our Gregorian calendar, the exact dates are determined based on the Hebrew calendar. It's purpose is to commemorate the re-dedication of the Second Temple of Jerusalem (around 160 BCE).
