گاهنبار (Gahanbar) is a Zoroastrian festival that celebrates the creation of the world and the seasonal changes. It consists of five major festivals, each corresponding to a different aspect of creation, such as the earth, water, and plants. These celebrations emphasize the importance of nature and the interconnectedness of all living things. During گاهنبار, Zoroastrians gather to perform rituals, share meals, and engage in community activities. The festivals promote unity and gratitude, allowing participants to reflect on their relationship with the divine and the environment. This tradition is an essential part of the Zoroastrian faith, highlighting the significance of harmony in life.
