Chaharshanbe Suri is one of the oldest traditional festivals in Iranian culture. It is celebrated on the evening of the last Wednesday of the year, beginning at sunset on Tuesday night and continuing into Wednesday. The celebration marks the informal beginning of the Nowruz festivities and symbolizes the transition from winter to the new year. The origins of Chaharshanbe Suri date back to ancient Iranian traditions, and many historians associate it with cultural practices from pre-Islamic Iran. In traditional Iranian culture, fire represents purity, light, and renewal. For this reason, fire plays a central role in the celebration. The most recognizable part of the festival is the lighting of bonfires and jumping over the flames. People gather in streets, courtyards, or open spaces and light small fires. Participants jump over the flames while chanting a traditional phrase that roughly translates to: “Take my sickness and give me your warmth and strength.” Symbolically, this phrase means giving the fire the illness and negativity of the past year and receiving vitality and energy in return. Chaharshanbe Suri also includes several other traditional customs practiced in different parts of Iran. One of the most well-known traditions is spoon-banging, known in Persian as Qashogh-zani. In this custom, young people cover their faces and go door to door carrying a bowl and spoon. By tapping the spoon against the bowl they signal their presence, and homeowners place nuts, sweets, or snacks into their bowls as a gesture of good fortune. The practice is traditionally seen as a symbolic way of seeking blessings and prosperity for the coming year. Another important part of the celebration is the preparation of Chaharshanbe Suri nuts, a mixture of dried fruits, nuts, and seeds traditionally associated with abundance and good luck in the new year. Families often gather together on this evening to share food, talk, and celebrate the approaching arrival of Nowruz. In some regions of Iran additional customs exist. One example is eavesdropping divination, where people symbolically listen to conversations of passersby and interpret the words they hear as signs about the coming year. Another tradition involves breaking a clay pot, symbolizing the removal of misfortune and negative energy from the past year. In recent decades the way the festival is celebrated in large cities has evolved, and fireworks and firecrackers have become common during the evening. Cultural historians often note that these elements are modern additions and were not part of the original tradition. Despite these changes, Chaharshanbe Suri remains one of the most important cultural celebrations in Iran. Every year on the night of the last Wednesday of the year, millions of people gather across cities and villages to light fires, perform traditional rituals such as spoon-banging, and celebrate together in anticipation of Nowruz.
