Months of the Assamese Calendar in 1980
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 1980, covering Bhaskarabda 1386 – 1387. A month marked part is one the Gregorian year cuts short at its own start or end.
| Month | Begins | Ends | Days |

What happened in the sky in 1980
Beyond the dates the Assamese Calendar lists, 1980 brought 5 eclipses - 2 solar and 3 lunar - of which 3 were above the horizon somewhere in India. The year also carried an Adhik Maas, the extra lunar month of Jyeshtha, running from 15 May 1980 to 12 June 1980. Uruka (Magh Bihu Eve) fell on 14 January, 1 day later in the year than in 1979 - a lunar year runs about eleven days short of a solar one.

The Assamese Calendar lists 15 dates in 1980. The first is Uruka (Magh Bihu Eve) on Monday, 14 January 1980, and the last is Raas Mahotsav on Saturday, 22 November 1980.
What are the main festival dates in the Assamese Calendar for 1980?
The first major observances of 1980 are:
- Uruka (Magh Bihu Eve) - Monday, 14 January 1980
- Magh Bihu (Bhogali Bihu) - Tuesday, 15 January 1980
- Saraswati Puja (Vasant Panchami) - Tuesday, 22 January 1980
- Maha Shivaratri - Thursday, 14 February 1980
- Doul Utsav (Holi) - Saturday, 1 March 1980
- Bohag Bihu (Rongali Bihu) - Sunday, 13 April 1980
Which traditional year does 1980 correspond to in the Assamese Calendar?
The Gregorian year 1980 spans Bhaskarabda 1386 – 1387. 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 1980 have an Adhik Maas?
Yes. 1980 carried an Adhik Maas (Jyeshtha (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 1980 dates can look out of place beside a neighbouring year.
Were there any eclipses in 1980?
1980 had 5 eclipses:
- 16 February 1980 - Total solar eclipse (Surya Grahan), visible in India, so Sutak Kaal was observed
- 2 March 1980 - Penumbral lunar eclipse (Chandra Grahan), penumbral only, so no Sutak was observed
- 28 July 1980 - Penumbral lunar eclipse (Chandra Grahan), penumbral only, so no Sutak was observed
- 11 August 1980 - Annular solar eclipse (Surya Grahan), not visible from India
- 26 August 1980 - Penumbral lunar eclipse (Chandra Grahan), not visible from India
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 1980?
Yes - 3 sign changes among the slow grahas in 1980:
- Shani (Saturn) entered Simha on 15 March 1980, moving retrograde
- Shani (Saturn) entered Kanya on 27 July 1980
- Guru (Jupiter) entered Kanya on 26 September 1980
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 1980?
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.
