While all current federal holidays have also been made public holidays in all 50 states for federal organizations, each state is not bound to observe the holidays on the same dates as the federal holidays. Many states also have additional holidays that are not observed by the U.S. federal government. Many businesses likewise observe certain holidays as well, which are also not mandated by any government agency. A list of ''recommended diversity holidays'' recognizes many cultures that range from Christianity to Islam, as well as racial diversity where various ethnic holidays such as St. Patrick's Day, Kwanzaa, Diwali, Mardi Gras, and Cinco de Mayo are celebrated by individuals in the workplace, as a matter of best practice. In light of recent race issues in the United States, many municipalities both at the city and state levels have begun celebrating Malcolm X Day and Rosa Parks Day in addition to Martin Luther King, Jr. Day to embrace the mostly disenfranchised African American community in the form of festivals and parades if not done as a legal public holiday. Illinois and Berkeley, California are two places where Malcolm X is honored with a legal holiday with offices closed whereas Missouri honored Rosa Parks on her birthday. Today, the United States is the 85th most ethnically diverse country in the world. While the popularity of each public holiday cannot easily be measured, the holiday with the highest greeting card sales is Christmas. Major retail establishments such as malls, shopping centers and most retail stores close only on Thanksgiving and Christmas and some on Easter Sunday as well, but remain open on all other holidays (early closing on Christmas Eve and New Year's Eve, and sometimes on other major holidays). Virtually all companies observe and close on the major holidays (New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas). Some non-retail business close on the day after Thanksgiving, while some (such as federal banks and post offices) are not allowed to close on the day after Thanksgiving. Some smaller businesses normally open on Sunday will close on Easter Sunday, if it is their experience they will have very few customers that day.
