12月25日，是基督教徒紀念耶穌誕生的日子，稱為聖誕節。
從12月24日於翌年1月6日為聖誕節節期。節日期間，各國基督教徒都舉行隆重的紀念儀式。聖誕節本來是基督教徒的節日，由於人們格外重視，它便成為一個全民性的節日，是西方國家一年中最盛大的節日，可以和新年相提並論，類似我國過春節。
西方人以紅、綠、白三色為聖誕色，聖誕節來臨時家家戶戶都要用聖誕色來裝飾。紅
色的有聖誕花和聖誕蠟燭。綠色的是聖誕樹。它是聖誕節的主要裝飾品，用砍伐來的杉、
柏一類呈塔形的常青樹裝飾而成。上面懸掛著五顏六色的彩燈、禮物和紙花，還點燃著聖
誕蠟燭。【您正瀏覽的文章由()整理，著作權歸原作者、原出處所有。】
紅色與白色相映成趣的是聖誕老人，他是聖誕節活動中最受歡迎的人物。西方兒童在
聖誕夜臨睡之前，要在壁爐前或枕頭旁放上一隻襪子，等候聖誕老人在他們入睡後把禮物
放在襪子內。在西方，扮演聖誕老人也是一種習俗。
聖誕節英語資料
Christmas, annual Christian holiday commemorating the birth of Jesus Christ. Most members of the Roman Catholic Church and followers of Protestantism celebrate Christmas on December 25, and many celebrate on the evening of December 24 as well. Members of the Eastern Orthodox Church usually delay their most important seasonal ceremonies until January 6, when they celebrate Epiphany, a commemoration of the baptism of Jesus. Epiphany also traditionally commemorates the arrival of the Three Wise Men of the East in Bethlehem (near Jerusalem, Israel), where they adored the infant Jesus and presented him with gifts of gold, frankincense, and myrrh. The official Christmas season, popularly known as either Christmastide or the Twelve Days of Christmas, extends from the anniversary of Christ’s birth on December 25 to the feast of Epiphany on January 6.
Christmas is based on the story of Jesus’ birth as described in the Gospel according to Matthew (see Matthew 1:18-2:12) and the Gospel according to Luke (see Luke 1:26-56). Roman Catholics first celebrated Christmas, then known as the Feast of the Nativity, as early as 336 ad. The word Christmas entered the English language sometime around 1050 as the Old English phrase Christes maesse, meaning “festival of Christ.” Scholars believe the frequently used shortened form of Christmas—Xmas—may have come into use in the 13th century. The X stands for the Greek letter chi, an abbreviation of Khristos (Christ), and also represents the cross on which Jesus was crucified.
各國聖誕節習俗：
法國法國中部的色日爾斯地方，每年聖誕節前後幾天必降大雪，白雪皚皚，令人清新。在西方人眼裡，白色聖誕是一種吉祥。在法國，馬槽是最富有特色的聖誕標誌，因為相傳耶穌是誕生在馬槽旁的。人們大唱頌讚耶穌的聖誕歌之後，必須開懷暢飲，香檳和白蘭地是法國傳統的聖誕美酒。
