Thanksgiving is a national holiday celebrated on various dates in October and November in the United States, Canada, Saint Lucia, Liberia, and unofficially in countries like Brazil, Germany and the 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. Various similarly named harvest festival holidays occur throughout the world during autumn. Although Thanksgiving has historical roots in religious and cultural traditions, it has long been celebrated as a secular holiday as well.
