Months of the Assamese Calendar in 2031
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 2031, covering Bhaskarabda 1437 – 1438. A month marked part is one the Gregorian year cuts short at its own start or end.

What the sky brings in 2031
Beyond the dates the Assamese Calendar lists, 2031 brings 5 eclipses - 2 solar and 3 lunar - of which 2 are above the horizon somewhere in India. The year also carries an Adhik Maas, the extra lunar month of Bhadrapada, running from 19 August 2031 to 16 September 2031. Uruka (Magh Bihu Eve) falls on 14 January, 1 day later in the year than in 2030 - a lunar year runs about eleven days short of a solar one.

Which month of 2031 has the most observances in the Assamese Calendar?
October 2031 is the fullest month with 4 dates, including Kati Bihu (Kongali Bihu), Durga Puja — Maha Ashtami, Vijayadashami, Lakshmi Puja.
Which traditional year does 2031 correspond to in the Assamese Calendar?
The Gregorian year 2031 spans Bhaskarabda 1437 – 1438. 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.
Will there be an Adhik Maas in 2031?
Yes. 2031 carries an Adhik Maas (Bhadrapada (Adhik)), the extra lunar month inserted roughly every third year to keep the lunar calendar in step with the solar one. Festivals falling after it shift later in the Gregorian year, which is why 2031 dates can look out of place beside a neighbouring year.
Will there be any eclipses in 2031?
2031 has 5 eclipses:
- 7 May 2031 - Penumbral lunar eclipse (Chandra Grahan), not visible from India
- 21 May 2031 - Annular solar eclipse (Surya Grahan), visible in India, so Sutak Kaal will be observed
- 5 June 2031 - Penumbral lunar eclipse (Chandra Grahan), penumbral only, so no Sutak will be observed
- 30 October 2031 - Penumbral lunar eclipse (Chandra Grahan), not visible from India
- 15 November 2031 - Partial solar eclipse (Surya Grahan), not visible from India
Sutak Kaal is observed only for an eclipse actually visible where you are, so 1 of these will be kept in India.
Will Guru or Shani change sign in 2031?
Yes - 3 sign changes among the slow grahas in 2031:
- Guru (Jupiter) enters Dhanu on 17 February 2031
- Guru (Jupiter) enters Vrishchika on 14 June 2031, moving retrograde
- Guru (Jupiter) enters Dhanu on 15 October 2031
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 2031?
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.
