This is contrary to Zoroastrian cosmology where all days were sacred and named after a major deity. By celebrating in this manner Iranians were able to preserve the ancient tradition. The festival is celebrated on Tuesday night to make sure all bad spirits are chased away and Wednesday will pass uneventfully.
