Maha Prodosham
The term pradosh refers to the evening time around sunset. … The most important highlights of the Pradosh Puja at temples include Abhishekam to Lord Shiva and Nandi (sacred bull) idols, and the chanting and singing at the temples.
The Mahapradosha Pooja is being performed from 1940 onwards. This is especially unique as it includes Mahanyasa Japam, Ekadasa Rudreabhishekam and concludes with Trishati Archana and Kramarchana, including all the Chamakas.
