in the USA, Thanksgiving is a national holiday celebrated on the 4th Thursday in November. It is a secular (non-religious) holiday. Traditionally it is observed with family gatherings and large meals, as it is a harvest feast and a day to stop and realize the things we have been blessed with in the past year.
Many other countries also have a Thanksgiving holiday. Canadian Thanksgiving is observed on the second Monday in October and is also a day to observe one's blessings.
For sales of products related to Thanksgiving. If the website sells products for a variety of holidays, it should be suggested instead to Shopping/Holidays/ or, if the products are mostly for a specific holiday, the website should be suggested to the corresponding category. For example, a website selling only Christmas lights should be suggested to Shopping/Holidays/Christmas/Decorations/Lights. By suggesting the website to the closest corresponding category, you make it much easier for Curlie volunteers to review the site.
