Maha Shivratri or the ‘Great’ night of lord Siva, also known as Padmarajrathri, is celebrated annually on the 13th night of the Maagha month of the Hindu calender. Celebrated on the dark fortnight or Krishna Paksha of Maagha, the festival is principally celebrated by chanting the sacred Panchakshara mantra, fasting, offering Bilva/Vilvam leaves to Lord Shiva followed by jagranas & havanas. This day is also known as the favorite day of Lord Shiva and the day when Shiva & Parvati got married.
