There are three major religious/cultural holidays celebrated in December:
Christmas: “Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the liturgical year in Christianity, it follows the season of Advent (which begins four Sundays before) or the Nativity Fast, and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night.”
Hanukkah: “Hanukkah is a Jewish festival commemorating the recovery of Jerusalem and subsequent rededication of the Second Temple at the beginning of the Maccabean Revolt against the Seleucid Empire in the 2nd century BCE. Hanukkah is observed for eight nights and days, starting on the 25th day of Kislev according to the Hebrew calendar, which may occur at any time from late November to late December in the Gregorian calendar. The festival is observed by lighting the candles of a candelabrum with nine branches, commonly called a menorah or hanukkiah.”
Kwanzaa: “Kwanzaa is an annual celebration of African-American culture from December 26 to January 1, culminating in a communal feast called Karamu, usually on the sixth day. It was created by activist Maulana Karenga, based on African harvest festival traditions from various parts of West, East, as well as Southeast Africa. Kwanzaa was first celebrated in 1966.”
