What Is Kalashtami?
Kalashtami (also Kala Ashtami) falls on the Ashtami of the Krishna Paksha every lunar month and is dedicated to Kaal Bhairav - the fierce, protective form of Lord Shiva. He is the lord of time (kaal), remover of fear, and is revered as the Kotwal (guardian) of Kashi (Varanasi).
His vahana is the dog, and he is shown holding a trishul and danda, often with a garland of skulls. Devotees worship him to destroy fear, enemies, negativity and obstacles, and to gain courage and protection. The grandest Kalashtami of the year is Kaal Bhairav Jayanti in the month of Margashirsha.
Kalashtami 2026 - Dates & Kaal Bhairav Jayanti
Kalashtami occurs once every lunar month on Krishna Paksha Ashtami, so there are twelve through the year. The exact date each month shifts with the tithi - check your panchang for the Ashtami nearest your puja.
The most important one: Kaal Bhairav Jayanti 2026 falls in Margashirsha, around 1 December 2026. This marks the day Kaal Bhairav appeared from Lord Shiva, and is celebrated with night vigils and special puja in Bhairav temples, especially in Kashi and Ujjain.
Kalashtami Vrat & Puja Vidhi
1. Morning: Bathe and take the sankalp to keep the vrat. Many fast through the day and worship at night, which is Bhairav's time. 2. Puja setup: Place an image of Kaal Bhairav (or worship at a Shiva/Bhairav temple). Light a lamp with mustard or sesame oil. 3. Offerings: Offer black sesame, urad, a garland of fragrant flowers, coconut, and prasad. Lighting a four-faced lamp is considered very auspicious. 4. Mantra jaap: Chant the Bhairav mantra 108 times with a rudraksha mala (see next section). 5. Feed a dog: Offer food to a dog, Bhairav's vahana - this is the most cherished act of the day. 6. Night vigil: Stay awake, sing Bhairav bhajans and read the Bhairav katha. Break the fast next morning after puja.
Powerful Kaal Bhairav Mantras
Chant any of these with faith, ideally facing a lamp at night:
Beej / simple mantra: Om Kaal Bhairavaya Namah
Batuk Bhairav mantra (for protection): Om Hreem Vam Batukaya Aapaduddharanaya Kuru Kuru Batukaya Hreem
For removing fear and obstacles: Om Bhayharanaya Namah
Start with the simple mantra if you are new. Use a rudraksha mala, keep the count steady at 108, and sit on a dark-coloured asan. Never rush the jaap.
Significance & Benefits
- Freedom from fear: Kaal Bhairav is the destroyer of fear, nightmares and unseen dangers.
- Protection: His worship is sought against enemies, black magic, accidents and negative energy.
- Removal of obstacles & Shani relief: Many worship him for relief from Shani dosha and stuck situations.
- Courage & discipline: The night vrat builds inner strength and fearlessness.
A simple, sincere act - lighting a lamp, chanting his name, and feeding a dog - is said to please Kaal Bhairav more than elaborate ritual without devotion.
