Pradhosha pooja is one of the most important among the poojas performed to the Graceful Lord Shiva. In Shukla Paksha (15 moon days from New moon to Full moon) and Krishna Paksha (15 moon days from Full moon to New moon) the evening of the trayodasi (thirteenth moon day) between 4.30 p.m. to 6.00 p.m. is called Pradhosha. It comes once in fifteen moon days. Pradhosha time is especially meant for praying Lord Shiva. Praying in that time will free us from out sins and gives moksha finally (hence the name Pradhosha). During pradoSha time a special type of circumambulating called soma sUtra pradaxiNam(1) is done

Evening of the 13th phase of the moon, 90 minutes before and after Sun set. It is considered auspicious for worshipping Shiva in all Saivite temples - when thousands congregate for worship.
