Months of the Assamese Calendar in 1991
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 1991, covering Bhaskarabda 1397 – 1398. A month marked part is one the Gregorian year cuts short at its own start or end.

What are the main festival dates in the Assamese Calendar for 1991?

- Uruka (Magh Bihu Eve) - Sunday, 13 January 1991
- Magh Bihu (Bhogali Bihu) - Monday, 14 January 1991

- Doul Utsav (Holi) - Thursday, 28 February 1991
- Bohag Bihu (Rongali Bihu) - Sunday, 14 April 1991
Which traditional year does 1991 correspond to in the Assamese Calendar?
The Gregorian year 1991 spans Bhaskarabda 1397 – 1398. 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 1991 have an Adhik Maas?
Yes. 1991 carried an Adhik Maas (Vaishakha (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 1991 dates can look out of place beside a neighbouring year.
Were there any eclipses in 1991?
1991 had 6 eclipses:
- 16 January 1991 - Annular solar eclipse (Surya Grahan), not visible from India
- 30 January 1991 - Penumbral lunar eclipse (Chandra Grahan), not visible from India
- 27 June 1991 - Penumbral lunar eclipse (Chandra Grahan), not visible from India
- 12 July 1991 - Total solar eclipse (Surya Grahan), not visible from India
- 26 July 1991 - Penumbral lunar eclipse (Chandra Grahan), penumbral only, so no Sutak was observed
- 21 December 1991 - Partial 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 1 of these was kept in India.
Did Guru or Shani change sign in 1991?
Yes - 1 sign change among the slow grahas in 1991:
- Guru (Jupiter) entered Simha on 14 August 1991
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 1991?
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.
