In the United States, every year, Thanks-giving Day is on the fourth Thursday in November. Because Canada is on the north of the United States, and is colder, the harvest comes earlier(更早) in the year. In Canada, people have Thanksgiving Day on the second Monday in October.

On Thanksgiving Day people in Canada and America like to have a big meal with their friends and family just like Chinese people do at Mid-autumn festival. Many Canadians and Americans put flowers, vegetables and fruits around their homes to say “Thank you” for the harvest.
