Karva Chauth 2025 sparked a massive ₹28,000 crore business across India, with Delhi leading at ₹8,000 crore, says the Confederation of All India Traders (CAIT). Markets saw huge crowds for sarees, jewellery, pooja thalis, and gifts as women observed the traditional fast. Traders credit the surge to festive spirit, GST relief, and PM Modi's call to promote Swadeshi products.
