Months of the Assamese Calendar in 2011
The Assamese Calendar does not begin its year on 1 January, so each of its months straddles two Gregorian ones. These are the months that ran through 2011, covering Bhaskarabda 1417 – 1418. A month marked part is one the Gregorian year cuts short at its own start or end.

October 2011 is the fullest month with 5 dates, including Durga Puja — Maha Ashtami, Vijayadashami, Lakshmi Puja, Kati Bihu (Kongali Bihu), Kali Puja (Diwali).
Which traditional year does 2011 correspond to in the Assamese Calendar?
The Gregorian year 2011 spans Bhaskarabda 1417 – 1418. The traditional year does not begin on 1 January, so one Gregorian year usually covers the end of one era year and the start of the next.
Did 2011 have an Adhik Maas?
No. 2011 had twelve lunar months with no Adhik Maas, so its festival dates fall in their usual Gregorian window rather than being pushed later by an intercalary month.
Were there any eclipses in 2011?
2011 had 6 eclipses:
- 4 January 2011 - Partial solar eclipse (Surya Grahan), visible in India, so Sutak Kaal was observed
- 2 June 2011 - Partial solar eclipse (Surya Grahan), not visible from India
- 16 June 2011 - Total lunar eclipse (Chandra Grahan), visible in India, so Sutak Kaal was observed
- 1 July 2011 - Partial solar eclipse (Surya Grahan), not visible from India
- 25 November 2011 - Partial solar eclipse (Surya Grahan), not visible from India
- 10 December 2011 - Total lunar eclipse (Chandra Grahan), visible in India, so Sutak Kaal was observed
Sutak Kaal is observed only for an eclipse actually visible where you are, so 3 of these were kept in India.
Did Guru or Shani change sign in 2011?
Yes - 2 sign changes among the slow grahas in 2011:
- Guru (Jupiter) entered Mesha on 8 May 2011
- Shani (Saturn) entered Tula on 15 November 2011
Jupiter takes about a year to cross one sign and Saturn about two and a half, so these transits colour the whole year rather than a single week.
How do I see the tithi and nakshatra for a specific date in 2011?
Use the month grid above: pick a month from the selector, then tap any day to open its full panchang - tithi with start and end times, nakshatra, yoga, karana, sunrise and sunset, and the inauspicious periods (Rahu Kalam, Yamaganda, Gulika Kalam). Set your city in the box at the top first, because these timings are sunrise-based and shift with location. The Assamese Calendar opens on the current month.
