Most of the people observe fast on Maha Shivaratri. The way fasting is observed has been changed with the time. The way Puja procedure has been suggested in religious texts is hardly followed during Shivaratri.
In current form of Puja Vidhi, devotees visit Shiva temples early in the morning. Most people finish Shiva Linga Puja before noon as most temples are closed after that in preparation of evening Darshan. Most Shiva temples open in the evening only for the Darshan and not for the Puja activities. In the morning devotees perform Abhishek with milk and water and offer different items to the Shiva Linga including Bilva leaves, Bilva fruit and Dhatura.
