Sindoor Tritiya, also known as Kumar Purnima, is a traditional Hindu celebration observed on the third day of the bright fortnight in the month of Ashwin. It is dedicated to the worship of Lord Ganesha and Devi Lakshmi for blessings of wealth and prosperity.

On this day, married women fast and perform special rituals to pray for the long life and well-being of their husbands. Sindoor, a red-orange powder, is applied to the parting of the hair and is considered auspicious in Hindu culture, symbolizing the bond of marriage.

The significance of Sindoor Tritiya lies in its association with marital happiness and prosperity, making it an important festival for Hindu families. The day is marked by elaborate puja rituals, offerings of fruits and sweets, and gatherings with loved ones to celebrate the occasion.
