November 24th is the "Thanksgiving Day" in the United States. In the United States, the fourth Thursday of November every year is "Thanksgiving Day". The whole country takes a two-day holiday, and everyone gathers together to celebrate this holiday.
In history, in 1620, some pilgrims boarded the "Mayflower" ship to America to seek religious freedom. After months of tossing on the sea, they finally arrived in Plymouth, Massachusetts in November. However, since it was the first time to arrive in this place, half of the landing people died in the harsh winter. The remaining people began to sow in the next year. Everyone was looking forward to a good harvest, which affected their survival here. However, they also unexpectedly got a good harvest in the harvest season. In order to thank God for the blessing, people reveled for three days, and this custom has continued to this day.
In 1863, US President Lincoln announced that the fourth Thursday of November every year would be officially designated as Thanksgiving Day. The whole family reunites on this holiday, which is equivalent to the Chinese Spring Festival. This is some of my understanding, I hope it can help you.
