Kartik 2026 begins October 27: why amanta calendars start two weeks later

The Hindu month of Kartik begins on Tuesday, October 27, 2026, in the purnimanta calendar followed across most of North India, and runs to Kartik Purnima on Tuesday, November 24, according to published panchangs. The month-long Kartik snan, the ritual early-morning bath, starts a day earlier, on Sharad Purnima, Monday, October 26. In the amanta calendar used in Maharashtra, Gujarat and much of South India, Kartik does not begin until November 10, 2026, and ends on December 8 or 9. The two-week gap comes from a simple difference in where each calendar places the start of a lunar month.

Every Hindu lunar month has two halves of about 15 days each: the waxing half, Shukla Paksha, which ends at the full moon (Purnima), and the waning half, Krishna Paksha, which ends at the new moon (Amavasya). The question is where the month begins. The purnimanta system, common in Uttar Pradesh, Bihar, Madhya Pradesh, Rajasthan and other northern states, ends each month on the full moon. The amanta system, common in Maharashtra, Gujarat, Karnataka, Andhra Pradesh and Telangana, ends each month on the new moon.

Because of this, the waxing half of a month carries the same name in both systems, but the waning half does not. The dark fortnight that a North Indian panchang calls the first half of Kartik is, in an amanta panchang, the second half of the month before, Ashwin. The festivals themselves fall on the same days; only the name of the month around them changes. This is why the same calendar date can be described as "Kartik Krishna" in Varanasi and "Ashwin Krishna" in Pune, and why the month appears to start about two weeks apart.

The dates this year show the effect clearly. Diwali, which panchangs place on November 8, 2026, falls inside the purnimanta Kartik that starts on October 27. Amanta calendars begin their Kartik only afterwards, on November 10. Both systems then share the bright fortnight that ends with Kartik Purnima: in purnimanta reckoning that full moon closes the month on November 24, while in amanta reckoning the month carries on for another fortnight to the new moon in early December.

According to tradition, Kartik is regarded as among the holiest months of the year. Devotees take an early bath, often in a river, light lamps (deep daan) in the evening, and worship the tulsi plant. Ekadashi in the bright half, known as Dev Uthani or Prabodhini Ekadashi, is believed by devotees to mark the god Vishnu waking from four months of rest, after which weddings and other ceremonies resume. These are matters of belief and practice, recorded in the panchangs and temple calendars, not scientific claims.

Short-term: Families and temples in the north begin the Kartik routine of early baths and evening lamps from October 26 and 27, while those following amanta calendars will mark the same month from November 10.

Long-term: Knowing which calendar a date comes from avoids confusion when relatives in different states, or diaspora families following different temple calendars, compare festival and fasting dates.

Who is affected: Devotees planning Kartik observances, temples and priests setting their calendars, pilgrims heading to river ghats for Kartik Purnima and Dev Deepavali, and anyone trying to match a festival date across regional panchangs.
