Kalabhairav Jayanti 2026 on December 1: why Kartik and Margashirsha agree

Kalabhairav Jayanti, the day tradition marks as the appearance of Kala Bhairava, a fierce form of Shiva, falls on Tuesday, December 1, 2026, according to most panchangs (Hindu almanacs) checked on October 30, 2026. The festival is observed on the Ashtami, or eighth lunar day, of the dark fortnight. Prokerala's panchang, calculated for Ujjain, gives the Ashtami tithi as running from about 12:12 am to 11:14 pm on December 1, and another listing gives almost the same window. A few websites list other dates in November, but these do not match the majority of calendars.

Kalabhairav Jayanti is a good example of a problem that confuses many readers every year: why the same festival is said to fall in Margashirsha by some and in Kartik by others. The answer lies in how Indian calendars count months. In the purnimanta system, common in north India, a month ends on the full moon, so the dark fortnight after Kartik Purnima already belongs to the next month, Margashirsha. In the amanta system, common in the south and west, a month ends on the new moon, so that same dark fortnight is still part of Kartik. The lunar day does not change; only its label does.

This matters in 2026 because Kartik Purnima falls on November 24. The dark fortnight that follows begins the next day, and its eighth day, Krishna Ashtami, falls on December 1. That is why the purnimanta calendar calls it Margashirsha Krishna Ashtami and the amanta calendar calls it Kartik Krishna Ashtami. Both are describing the same day.

According to tradition, Kala Bhairava is the form of Shiva associated with time and with the protection of sacred places. Festival accounts tell that after Bhairava was freed from the sin of killing a Brahmin in Kashi, he was given the duty of guarding the city, which is why he is called Kashi ka Kotwal. According to the Shiva Purana, as cited in festival accounts, Bhairava appeared on the Ashtami of the dark fortnight of Margashirsha. Devotees mark the day with fasting, puja and the chanting of Bhairava mantras, and Kala Bhairava temples, including the one in Varanasi, see large crowds.

The monthly Kalashtami, the Ashtami of every dark fortnight, is also linked to Bhairava, and this may explain why some websites give other dates in November: those may be monthly Kalashtami days rather than the annual Jayanti.

Short-term: Devotees and temples planning the festival can mark Tuesday, December 1, and check a local panchang for the exact tithi window in their city.

Long-term: Knowing how purnimanta and amanta months are counted helps readers make sense of other festivals that appear to fall in different months in north and south Indian calendars.

Who is affected: Devotees of Shiva and Kala Bhairava, temples in Varanasi, Ujjain and elsewhere, families who follow the panchang, and readers who find conflicting dates online.
