American culture involves celebrating many holidays throughout the year. Some of the major holidays include New Year's Eve where people watch the ball drop in Times Square, Valentine's Day where children exchange cards at school, Easter which involves egg hunts and dying eggs, Halloween where people carve pumpkins and go trick-or-treating, Thanksgiving which centers around a large meal with turkey, and Christmas where children leave milk and cookies for Santa. Americans also celebrate Independence Day with fireworks and barbecues, Mother's Day by doing something nice for mothers, and smaller holidays like Groundhog Day, Super Bowl Sunday, and Earth Day.
