Yom Kippur (Hebrew: יוֹם כִּפּוּר or יום הכיפורים‎, IPA: [ˈjom kiˈpur]), also known as Day of Atonement, is the holiest and most solemn day of the year for the Jews. Its central themes are atonement and repentance. Jews traditionally observe this holy day with a 25-hour period of fasting and intensive prayer, often spending most of the day in synagogue services. Yom Kippur completes the annual period known in Judaism as the High Holy Days or Yamim Nora'im ("Days of Awe").

Yom Kippur is the tenth day of the month of Tishrei. According to Jewish tradition, God inscribes each person's fate for the coming year into a book, the Book of Life, on Rosh Hashanah, and waits until Yom Kippur to "seal" the verdict. During the Days of Awe, a Jew tries to amend his or her behavior and seek forgiveness for wrongs done against God (bein adam leMakom) and against other human beings (bein adam lechavero). The evening and day of Yom Kippur are set aside for public and private petitions and confessions of guilt (Vidui). At the end of Yom Kippur, one considers oneself absolved by God.

Many countries in the New World and elsewhere celebrate the anniversary of Christopher Columbus's arrival in the Americas, which occurred on October 12, 1492, as an official holiday. The event is celebrated as Columbus Day in the United States, as Día de la Raza in many countries in Latin America, as Discovery Day in the Bahamas, as Día de la Hispanidad, Fiesta Nacional in Spain, Día del Respeto a la Diversidad Cultural (Day of Respect for Cultural Diversity) in Argentina and as Día de las Américas (Day of the Americas) in Uruguay. These holidays have been celebrated unofficially since the late 18th century, and officially in various areas since the early 20th century.

Columbus Day first became an official state holiday in Colorado in 1906, and became a federal holiday in 1937, though people have celebrated Columbus' voyage since the colonial period. In 1792, New York City and other U.S. cities celebrated the 300th anniversary of his landing in the New World. President Benjamin Harrison called upon the people of the United States to celebrate Columbus Day on the 400th anniversary of the event. During the four hundredth anniversary in 1892, teachers, preachers, poets and politicians used Columbus Day rituals to teach ideals of patriotism. These patriotic rituals were framed around themes such as support for war, citizenship boundaries, the importance of loyalty to the nation, and celebrating social progress.^[1][2]
