Thanksgiving Day is a special holiday in the United States and Canada. Families and friends gather to eat and give thanks for God’s blessing.

Thanksgiving Day is really a harvest festival. That is why it’s celebrated in late autumn. But the first Thanksgiving Day in America had nothing to do with a good harvest. On December 4, 1619, the Pilgrims from England landed near what is now Charles City, Virginia. They knelt down and thanked God for their safe journey across the Atlantic.

The first Thanksgiving Day in New England did celebrate a rich harvest. The Pilgrims landed at what is now Plymouth, Massachusetts, in 1620. They had a difficult time and the first winter was cruel. Many of the Pilgrims died. But the next year, they had a good harvest. So Governor Bradford declared a three-day feast(盛宴). The Pilgrims invited Indian friends to join them for their special feast. Everyone brought food.

After that, other colonies(殖民地)began to celebrate the day of thanksgiving. But it took years before there was a national Thanksgiving Day. During the Civil War, Sarah Josepha Hale persuaded Abraham Lincoln to do something about it. He proclaimed(宣布)the last Thursday of November, 1863 as the day of thanksgiving. Today, Americans celebrate this happy harvest festival on the fourth Thursday in November. Canadians celebrate Thanksgiving Day in much the same way as their American neighbours do. But Thanksgiving Day in Canada falls on the second Monday in October.
