This report examines the history and development of various American traditions, from national holidays to university rituals, and how they have been adopted by other countries.

本報告旨在探討各種美國傳統的歷史與發展，從國家假期到大學儀式，以及其他國家如何採納這些傳統。

Many American national holidays began long before the federal government was officially established. For example, Thanksgiving started in 1621, although Abraham Lincoln did not make it an official national holiday until 1863. Similarly, fireworks for Independence Day were recorded as early as 1777, but it was not recognized as a paid holiday until 1938. Other civic events, such as the presidential inauguration, follow a mix of legal requirements and tradition; while the oath of office is required by law, using a Bible is a custom rather than a legal rule.

許多美國國家假期在聯邦政府正式成立之前就已經存在。例如，感恩節始於1621年，儘管亞伯拉罕·林肯直到1863年才將其定為正式國家假期。同樣地，獨立日燃放煙火早在1777年就有記錄，但直到1938年才被認可為有薪假期。其他公民活動，如總統就職典禮，則是法律要求與傳統的結合；雖然就職宣誓是法律規定，但使用聖經是一種習俗而非法律規則。

Many social traditions were created by business interests or the influence of immigrants. For instance, putting pickle-shaped ornaments on Christmas trees started as a marketing idea by Woolworths in the late 19th century, while pumpkin carving is believed to have come from Irish immigrants. Furthermore, gift-giving during Hanukkah became popular in the 1920s because children wanted to have similar experiences to those celebrating Christmas. In sports and education, events like the World Series and the Army-Navy football game have provided long-term stability since the turn of the century.

許多社交傳統是由商業利益或移民影響而創造的。例如，在聖誕樹上掛醃菜形狀的裝飾品是19世紀末由Woolworths提出的營銷創意，而雕刻南瓜則被認為源自愛爾蘭移民。此外，光明節送禮在1920年代變得流行，因為孩子們希望擁有與慶祝聖誕節相似的體驗。在體育與教育方面，如世界系列賽和陸軍-海軍足球賽等活動，自世紀之交以來便提供了長期的穩定性。

Outside of the US, American cultural exports have spread to other societies, a process often called 'Americanisation.' The adoption of the 'prom' in the United Kingdom is a clear example of this trend. However, this transition often creates a conflict, as the UK adopts the American style of formal dress without having the same social rules or legal frameworks, such as the specific alcohol laws found in the United States.

在美國之外，美國的文化輸出傳播到了其他社會，這一過程通常被稱為「美國化」。英國採納「畢業舞會」（prom）就是這一趨勢的一個明顯例子。然而，這種轉型經常造成衝突，因為英國採納了美國的正式著裝風格，卻沒有相同的社交規則或法律框架，例如美國特定的酒精法律。

American traditions continue to survive through a combination of government support, commercial advertising, and international cultural exchange.

美國傳統透過政府支持、商業廣告與國際文化交流的結合，得以持續生存。
