Carve a Pumpkin Day is observed on October 31, 2016. Pumpkins are commonly carved into decorative lanterns called jack-o'-lanterns for the Halloween season in North America. The practice of craving pumpkins for Halloween orginated from an Irish myth about a man name "Stingy Jack". In the United States, the carved pumpkin was first associated with the harvest season in general, long before it became an emblem of Halloween.
Sections of the pumpkin are cut out to make holes, often depicting a face, which may be either cheerful, scary, or comical. A variety of tools can be used to carve and hollow out the gourd, ranging from simple knives and spoons to specialized instruments, typically sold in holiday sections of North American grocery stores. Printed stencils can be used as a guide for increasingly complex designs.
After carving, a light source (traditionally a candle) is placed inside the pumpkin and the top is put back into place. The light is normally inserted to illuminate the design from the inside and add an extra measure of spookiness. Sometimes a chimney is carved, too. It is possible to create surprisingly artistic designs, be they simple or intricate in nature. (With material from: Wikipedia)
