Midwinter Festival, Bahman 15. This festival is one of the traditional Iranian observances held in the middle of winter. Historically, people marked this day as a sign of reaching the midpoint of winter and the gradual approach of warmer days. The celebration often included gatherings, merriment, and sometimes the lighting of fires. Today, the Midwinter Festival is mostly symbolic and is still observed in some regions of Iran on a smaller scale. The tradition reflects the importance of the natural cycle and seasonal changes in Iranian culture, serving as a reminder of hope for the coming of spring and the end of the cold season.
