Which traditional year does 1973 correspond to in the Assamese Calendar?
The Gregorian year 1973 spans Bhaskarabda 1379 – 1380. 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 1973 have an Adhik Maas?
No. 1973 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 1973?
1973 had 7 eclipses:
- 4 January 1973 - Annular solar eclipse (Surya Grahan), not visible from India
- 19 January 1973 - Penumbral lunar eclipse (Chandra Grahan), penumbral only, so no Sutak was observed
- 16 June 1973 - Penumbral lunar eclipse (Chandra Grahan), penumbral only, so no Sutak was observed

- 10 December 1973 - Partial lunar eclipse (Chandra Grahan), visible in India, so Sutak Kaal was observed
- 24 December 1973 - Annular solar eclipse (Surya Grahan), not visible from India
Sutak Kaal is observed only for an eclipse actually visible where you are, so 2 of these were kept in India.
Did Guru or Shani change sign in 1973?
Yes - 2 sign changes among the slow grahas in 1973:
- Guru (Jupiter) entered Makara on 25 January 1973
- Shani (Saturn) entered Mithuna on 10 June 1973
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 1973?
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.
