美国人星期一庆祝哥伦布日。每年十月第二个星期一是纪念哥伦布到达美洲的哥伦布日，属于联邦假日。意大利探险家哥伦布受命西班牙国王，四次率领船队探索新世界，但从来没有完成他最初的目标，也就是找到一条向西通往亚洲的海上航线。哥伦布为探险者开辟了美洲大陆，使世界历史进入一个新时代。
哥伦布日在1971年成为美国假日。银行、州政府办公室、邮局和联邦机构都会放假。债券市场休市，但许多商家和股票交易所继续开放。
Americans are celebrating Columbus Day Monday.Columbus Day is a federal holiday observed on the second Monday in October, marking the anniversary of the arrival of Christopher Columbus to the Americas. Columbus, an Italian explorer sailing under the Spanish flag, led four expeditions to the New World, but never accomplished his original goal — to find a western ocean route to Asia. Instead, Columbus ushered in a new era in world history by opening up the Americas to exploration.
Columbus Day became a U.S. holiday in 1971. It is generally observed by banks, state government offices, the Postal Service and federal agencies. The bond markets are closed for the holiday, but many businesses and stock exchanges remain open.
