Carnival is a Western Christian 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. 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 during Shrovetide as to reduce waste. This festival is known for being a time of great indulgence before Lent, with drinking, overeating, and various other activities of indulgence being performed. For example, pancakes, donuts, and other desserts are prepared and eaten for a final time. During Lent, lacticinia and animal products are eaten less, and individuals make a Lenten sacrifice, thus giving up a certain object or activity of desire.
