Pradosh Vrat is an important Hindu observance dedicated to Lord Shiva. It is observed on the 13th day (Trayodashi) of both the Shukla Paksha and Krishna Paksha phases of the lunar fortnight. The word "Pradosh" means "the period just before dusk," and the vrat (fast) is typically performed during this time, when it is believed that Lord Shiva and Goddess Parvati are most receptive to prayers.

Significance: Pradosh Vrat holds great significance in Hinduism as it is believed to remove sins, fulfill desires, and bring peace, prosperity, and happiness to devotees. Observing this fast with devotion is said to attract the blessings of Lord Shiva and Goddess Parvati, helping devotees overcome obstacles and achieve spiritual growth.

1. Nitya Pradosh: Observed on every Trayodashi.
2. Shani Pradosh: Falls on a Saturday, considered particularly powerful.
