Dhanteras (Dhantrayodashi) for 2025 falls on October 18, 2025 (Saturday) according to the Hindu calendar and Panchang sources. This is the first day of the five-day Diwali period; the main Diwali Lakshmi Puja is typically observed a couple of days later, around October 20–21, 2025 depending on local panchang. If you need a specific regional date, please share your city or region, and I can refine it.
