A. Chinese New Year

     Chinese New Year is the most important of the traditional Chinese holidays. It falls on different dates each

year, between January 21 and February 20. Visits to friends and family take place during this celebration. The

color gold is said to bring wealth, and the color red is considered especially lucky. The New Year's Eve dinner

is very large and includes fish, noodles, and dumplings. 

B. Christmas

     Christmas is celebration of the birth of Jesus Christ. Christmas in the United States brings together many

customs from other countries and cultures. Around the world, family members help to decorate the tree and

home with bright lights, wreaths, candles, holly, mistletoe, and ornaments. On Christmas Eve, many people go

to church. Also on Christmas Eve, Santa comes from the North Pole in a sleigh to deliver gifts; in Hawaii, it is

said he arrives by boat; in Australia, the jolly man arrives on water skis; and In Ghana, he comes out of the

jungle.

C. Eid Al Adha, the Festival of the Sacrifice

     Eid Al Adha is celebrated by Muslims on the 10th day of the month of the lunar calendar (In 2008, it fell on

December 8) to commemorate the willingness of the prophet Ibrahim (or Abraham) to sacrifice his son for

God. Today, Muslims sacrifice an animal-usually a goat or a sheep-as a reminder of Ibrahim's obedience to

God. The meat is shared with family, friends Muslims or non-Muslims, as well as the poor members of the

community.

D. Hanukkah

     Jewish people celebrate Hanukkah, a holiday honoring the Maccabees victory over King Antiochus, who

forbade Jews to practice their religion. For eight nights, Hanukkah is celebrated with prayer, the lighting of the

menorah, and food. A menorah has nine candles, a candle for every night, plus a helper candle. Children play

games, sing songs, and exchange gifts. Potato pancakes, known as latkes (土豆饼) in Yiddish, are traditionally

associated with Hanukkah and are served with applesauce and sour cream.

E. Kwanzaa

     On December 26, Kwanzaa is celebrated. It is a holiday to commemorate African heritage. Kwanzaa lasts

a week during which participants gather with family and friends to exchange gifts and to light a series of black,

red, and green candles, which symbolize the seven basic values of African American family life that are unity,

self-determination, collective work and responsibility, cooperative economics, purpose, creativity, and faith.

F. Three Kings Day

     At the end of the Twelve Days of Christmas comes a day called the Epiphany, or Three Kings Day. This

holiday is celebrated as the day the three wise men first saw baby Jesus and brought him gifts. On this day in

Spain, many children get their Christmas presents. In Puerto Rico, before children go to sleep on January 5,

they leave a box with hay under their beds so the kings will leave good presents. In France, a delicious King

cake is baked. Bakers will hide a coin, jewel or little toy inside it.
