Chaitra Parva takes its name from Chaitra, the month in the Odia solar calendar in which it falls, and is known locally as Chal-it Parab, the spring festival. Its timing follows the solar transition marked by Maha Vishuva Sankranti, generally falling in mid-April, and it functions as both a seasonal marker, the turn from the old agricultural year into the new, and a religious occasion built around Shaiva mythology. In the version most closely tied to the Seraikella tradition of Chhau, the festival stages the moment Shiva lies in yogic sleep and his wife Shakti wakes him; roused, Shiva dances, and that dance is read as bringing the universe and the passage of time itself into being. Performances across the festival's several days are understood to trace the soul's own passage through the cosmic ages that follow from that first dance.
The festival is observed across the eastern Indian region where Chhau dance itself is rooted, chiefly Odisha, with related observance in the neighboring Chhau centers of Jharkhand and West Bengal. Its religious content sits alongside a plainer agricultural one: Chaitra Parva marks the turn of the farming year in a region where the dance traditions built around it fuse movement drawn from martial training with gestures borrowed from village agricultural life, so the festival's mythic staging and its seasonal timing reinforce each other rather than sitting apart. It remains a living annual observance rather than a historical curiosity, still drawing the same open-ground night performances it has for generations.
