There are 2 main American holidays and traditions in the USA: Thanksgiving and Independence day.
Thanksgiving is celebrated since 1621 by the pilgrims and native Americans.
Sarah Hale, a magazine writer, asked five presidents to make it a national holiday from 1846 to 1863 and Lincoln made it a national holiday in 1863.
Today most Americans spend it with their families and they have a special meal (turkey, yams, mashed potatoes, pumpkin pìe, and cramberry sauce).
Some of them watch the Macy's Thankgiving Day Parade in New York on TV.
The Independence Day is celebrated on 4th July because it was on this date in 1775 when the Declaration of Independence of the USA was published.
People usually hang the American flag and have picnics and barbecues ( They often eat hamburgers, hot dogs, corn, watermelon and ice cream).
At night there are fireworks and concerts too.
