Pradosha Vrat is observed on both Trayodashi Tithis, i.e. Shukla Paksha Trayodashi and Krishna Paksha Trayodashi, in lunar month. For Pradosham Vrat, day is fixed when Trayodashi Tithi falls during Pradosha Kala which starts after Sunset. The time window after Sunset when Trayodashi Tithi and Pradosha time overlaps is auspicious for Shiva Puja.
When Pradosham day falls on Wednesday, it is known as Budha Pradosha. Budha Pradosha Vrat is observed to please Lord Shiva. Wednesday is governed by the Lord Budha, i.e. planet Mercury and therefore, the Pradosha falling on a Wednesday is considered beneficial for achieving success in intellect, speech, and business. Observing Budha Pradosha Vrat enhances one's mental abilities, communication skills, and eloquence.
In astrology, this fast is considered very effective. It is recommended for individuals facing inauspicious combinations related to Budha in their Kundali. Budha is believed to govern speech, intellect, reasoning, communication, mathematics, and commerce. Therefore, this fast is especially fruitful for students and businessmen.
