Holidays Like other Hispanic communities, Cuban Americans tend to observe traditional Roman Catholic holidays, such as Christmas and Easter. Cuban Americans may also celebrate Three Kings' Day (January 6), marking the day when the “three wise men” delivered gifts to Jesus Christ. Additionally, many Cubans celebrate All Saints' Day (November 1), commemorating those who have achieved sainthood, and All Souls' Day (November 2), sanctifying the souls that remain in purgatory. While celebration of the 1959 Cuban Revolution is a hotly contested issue among many Cuban Americans, many immigrants from Cuba observe Cuban Independence Day on May 20, celebrating the nation's independence from Spain.
