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 Monday, it is known as Soma Pradosha. Soma Pradosha Vrat is considered one of the most beloved fasts of Lord Shiva. This fast is regarded as highly beneficial for mental peace, marital happiness, and family prosperity. According to Vedic astrology, this fast is very effective in resolving inauspicious combinations related to the Lord Chandra in one's Kundali.
When observed with proper rituals, this fast brings desired results through the blessings of Lord Shiva. Soma Pradosha Vrat is especially recommended to enhance love, harmony, and sweetness in married life. Additionally, it is also considered suitable for overcoming mental problems and stress.
