When did America or Europe begin to prepare for Christmas?

In the United States, Christmas shopping begins immediately after Thanksgiving, so the Friday immediately after it is usually called "Black Friday". This year, Wal-Mart in an American city even crushed/trampled a person to death. It has to be said that the lives of ordinary people are "manipulated" by businesses to a great extent, so people begin to prepare for Christmas at this time.

In fact, as a religious festival, the initial preparation for Christmas is four sundays from Christmas Eve, which is called the first to the fourth March, meaning "coming". Each family will make their own garlands or buy them from supermarkets and flower shops, and put four candles on them, one on the first Sunday, two on the second Sunday, and so on. When four candles are lit together, Christmas will come soon. There are also special activities in the church at this time. In Germany with a strong religious flavor, the Christmas market will be officially opened on the Friday before the first Advent and will last until Christmas Eve. You can buy all kinds of decorations, handicrafts and candles, as well as special fried almonds, Gluehwein (a drink made of red wine, spices and juice, but excluding children's alcohol), barbecue, honey pepper cake and so on. The most famous Christmas market in Germany is the El Nino market in Nuremberg, which attracts a large number of tourists every year. This year, the Germans also put the Christmas market in big cities such as London, England and Brussels, the capital of the European Union. The popularity is beyond imagination.
