The Harvest Festival of Thanksgiving does not have an official date in the United Kingdom, however it is traditionally held on or near the Sunday of the harvest moon that occurs closest to the autumnal equinox. Harvest Thanksgiving in Britain pre-dates Christianity when the Saxons would offer the first sheaf of corn to fertility gods. When the harvest was finally collected, communities would come together for a harvest supper. When Christianity arrived in Britain many traditions remained, and today Harvest Thanksgiving is marked by churches and schools in late September/early October (same as Canada) with singing, praying and decorating with baskets of food and fruit to celebrate a successful harvest and to give thanks.Collections of food are usually held which are then given to local charities which help the homeless and those in need.

American-style Thanksgiving is currently on the rise in the United Kingdom, with 1 in 6 Britons now celebrating the holiday. This is believed to be a result of Britain’s close connections with the US and Canada, as well as the influence of American culture on the UK. In 2014, it was reported that Turkey sales increased by 95% as a result of the rise in popularity of Thanksgiving in Britain.(wikipedia)
