Thanksgiving Day
Thanksgiving Day is a public holiday in the United States.It now comes on the fourth Thursday in November. This is a day for family reunions. Thanks are offered in the churches for the blessings* of the year, and at home a big dinner that usually includes roast turkey and cranberry sauce** is served.
Thanksgiving is a harvest festival, and is one of the oldestand most popular celebrations in the worid. The original celebration in the United States was held in 1621 after the first harvest in New England. The Pilgrims had sailed across the Atlantic Ocean on the “Mayflower,” arriving December 21, 1620. Only half of the original band survived the cold winter. But the first harvest, fortunately, was good.
The date of this first feast is not known and there is norecord that it was called “thanksgiving.” But two years later the Pilgrims set apart a day of thanks for rain that put an end to along dry period. Later, Thanksgiving days following harvest came to be celebrated in all the colonies of New England, but not on the same day. It was during the third year of the Civil War, October 3, 1863, that President Abraham Lincoln proclaimed a national Thanksgiving. In 1951, the United States Congress named the fourth Thursday o f November a Thanksgiving Day.
Canada has long celebrated a Thanksgiving Day. It is nowalways the second Monday in October. They also like turkey, served with fresh vegetables and fruits. Many people go to church in the morning. The first annual Thanksgiving for all the Canadian provinces was October 9: 1879.
