Carnival (see other spellings and names) is a Western Christian and Greek Orthodox festive season that occurs before the liturgical season of Lent. The main events typically occur during February or early March, during the period historically known as Shrovetide (or Pre-Lent). Carnival typically involves public celebrations, including events such as parades, public street parties and other entertainments, combining some elements of a circus. Elaborate costumes and masks allow people to set aside their everyday individuality and experience a heightened sense of social unity. Participants often indulge in excessive consumption of alcohol, meat, and other foods that will be forgone during upcoming Lent. Traditionally, butter, milk, and other animal products were not consumed "excessively", rather, their stock was fully consumed as to reduce waste. Pancakes, donuts, and other desserts were prepared and eaten for a final time. During Lent, animal products are no longer eaten, and individuals have the ability to give up a certain object or activity of desire.
