How is the setting in the story The Lottery important?

Jackson establishes the setting of "The Lottery" at the beginning of the story. It takes place on the morning of June 27th, a sunny and pleasant summer day, in the village square of a town of about three hundred people. The setting is described as tranquil and peaceful, with children playing and adults talking about everyday concerns. This seemingly normal and happy setting contrasts greatly with the brutal reality of the lottery. Few clues are given to a specific time and place in the story, a technique used to emphasize the fact that such brutality can take place in any time or in any place.
