Shivaratri is celebrated on the 6th night of the dark Phalgun (Feb or March) every year. On the auspicious day, devotees observe fast and keep vigil all night. Mahashivaratri marks the night when Lord Shiva performed the ‘Tandava’. It is also believed that on this day Lord Shiva was married to Parvati Ma. On this day Shiva devotees observe fast and offer fruits, flowers and bel leaves on Shiva Linga.
