Thanksgiving is a holiday celebrated in much of North America, generally observed as an expression of gratitude, usually to God. The most common view of its origin is that it was to give thanks to God for the bounty of the autumn harvest. In the United States, the holiday is celebrated on the fourth Thursday in November. In Canada, where the harvest generally ends earlier in the year, the holiday is celebrated on the second Monday in October, which is observed as Columbus Day or protested as Indigenous Peoples Day in the United States.Thanksgiving is traditionally celebrated with a feast shared among friends and family. In the United States, it is an important family holiday, and people often travel across the country to be with family members for the holiday. The Thanksgiving holiday is generally a "four-day" weekend in the United States, in which Americans are given the relevant Thursday and Friday off. Thanksgiving is almost entirely celebrated at home, unlike the Fourth of July or Christmas, which are associated with a variety of shared public experiences (fireworks, caroling, etc.)感恩节的由来要一直追溯到美国历史的发端。1620年，著名的五月花号船满载不堪忍受英国国内宗教迫害的清教徒102人到达美洲。1620年和1621年之交的冬天，他们遇到了难以想象的困难，处在饥寒交迫之中，冬天过去时，活下来的移民只有50来人。这时，心地善良的印第安人给移民送来了生活必需品，还特地派人教他们怎样狩猎、捕鱼和种植玉米、南瓜。在印第安人的帮助下，移民们终于获得了丰收，在欢庆丰收的日子，按照宗教传统习俗，移民规定了感谢上帝的日子，并决定为感谢印第安人的真诚帮助，邀请他们一同庆祝节日。在第一个感恩节的这一天，印第安人和移民欢聚一堂，他们在黎明时鸣放礼炮，列队走进一间用作教堂的屋子，虔诚地向上帝表达谢意，然后点起篝火举行盛大宴会。第二天和第三天又举行了摔交、赛跑、唱歌、跳舞等活动。第一个感恩节非常成功。其中许多庆祝方式流传了300多年，一直保留到今天。初时感恩节没有固定日期，由各州临时决定，直到美国独立后，感恩节才成为全国性的节日。 1863年，美国总统林肯正式宣布感恩节为国定假日。届时，家家团聚，举国同庆，其盛大、热烈的情形，不亚于中国人过春节。
