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 Saturday, it is known as Shani Pradosha.
