How to fast for Mahashivratri: Rules that most people don’t know

Mahashivratri, the Great Night of Lord Shiva, is one of the most powerful and sacred Hindu festivals. It is a night filled with energy and vibrations, all of them positive and jolly, and devotees immerse themselves in the love and devotion of Lord Shiva. The night is spent in meditation, chanting, dancing, and moving freely to connect with your energies and that of the divine.
In 2025 Mahashivratri will be February 26, and people will fast from morning to next sunrise to align their energies with Shiva.

Over the years and decades, there have been different interpretations of why Shivratri is celebrated. And while most people are of the belief and opinion that it is the great night when Lord Shiva and Maa Parvati got married, others think it means something else and there isn’t enough evidence to support the claim of marriage.
Most popular belief says that Mahashivratri marks the divine wedding of Lord Shiva and Goddess Parvati, another says that Mahashivratri is the night when Lord Shiva performed the Tandav, and some others say that on the night of Mahashivratri Lord Shiva drank the Halahal, saving the universe.

The devotees of Lord Shiva fast on the day and night of Mahashivratri to show their devotion, their love, and their respect for Lord Shiva. Some undertake a Nirjala vrat, where they do not eat or drink anything for over 24 hours, breaking the fast only after sunrise the next day. Whereas others prefer to keep a no-grain fast where they only eat light fruits and uncooked foods through the day to keep their system light.

The fast for Mahashivratri starts on the day it is being observed and ends the next day, post sunrise. So in 2025, devotees will observe fasting from early morning on February 26 to the sunrise of February 27. It is a strict 24+ hour fast and devotees choose to keep a Nirjala fast or a no-grain fast, depending on their health and routines.

Although the morning of Mahashivratri is light and easy and people go on with their daily routines, it is the night that sees chantings, meditation, and immersing oneself in the energy of Lord Shiva.
Before beginning the fast, devotees take a vow with a pure heart and let Lord Shiva know their intention behind keeping the fasting. They also wake up early, take a shower, clean the home temple, perform Abhishekam on the Shivling, and offer Lord Shiva bel patra and ber.
There are chants of ‘Om Namah Shivay’ in the air and the Mahamrityunjay mantra is heard and recited by devotees.

In Mahashivratri, the night timings are divided into 4 Prahar times. The first Prahar will start in the evening of February 26, and these go on till early morning of February 27.

According to Drik Panchang, the Prahar timing this year is - “Ratri First Prahar Puja Time - 06:19 PM to 09:26 PM
Ratri Second Prahar Puja Time - 09:26 PM to 12:34 AM, Feb 27Ratri Third Prahar Puja Time - 12:34 AM to 03:41 AM, Feb 27Ratri Fourth Prahar Puja Time - 03:41 AM to 06:48 AM, Feb 27”

The importance of fasting on Mahashivratri is much more than just a detox for your system. When you are fasting and your body and the digestive processes are at rest, your mind has a better chance at connecting with the energies around you. It has a better chance to let you be at rest in the meditative state and align yourself with the energies around. The fasting also helps in self-purification, improves your concentration, self-discipline, and inner peace, and helps you control the mental chatter during the silent meditations.

On the night of Mahashivratri, while some people prefer to observe silent meditation, others chant mantras to keep their mind aligned with the energies of Lord Shiva. The most common and easy mantra to connect with Lord Shiva is 'Om Namah Shivay' and 'Har Har Mahadev'. Others like to chant the Mahamrityunjay mantra, while some others listen to the ShivTandav Stotram.

Although all devotion and kindness begins at home, and there is no temple greater than the one within us, there are certain powerful Shiva temples where people like to go on Mahashivratri and other days.

For example, the Kashi Vishwanath temple in Varanasi, the Baidyanath temple in Jharkhand, the Mahakaleshwar temple in Ujjain, the Somnath temple in Gujarat, and many more.
