Mothers have been celebrated around the world since the days of ancient Greeks and Romans.
In the United States, Mother's Day became a national holiday after an effort by Anna Jarvis "as a way of honoring the sacrifices mothers made for their children." U.S. President Woodrow Wilson signed a measure in 1914 to officially set Mother's Day on the second Sunday of May.
Americans celebrate mothers by buying them gifts, taking them out for a meal, or surprising them with their favorite treat. Mother's Day cards, either bought or made, are a big part of this special day.
