Thanksgiving is a national holiday celebrated on various dates in the United States, Canada, Grenada, Saint Lucia, Liberia, and unofficially in countries like Brazil and Philippines. It is also observed in the Dutch town of Leiden and the Australian territory of Norfolk Island. It began as a day of giving thanks for the blessings of the harvest and of the preceding year (Similarly named harvest festival holidays occur throughout the world during autumn, including in Germany and Japan.).
