Months of the Assamese Calendar in 2010
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 2010, covering Bhaskarabda 1416 – 1417. A month marked part is one the Gregorian year cuts short at its own start or end.

The year also carried an Adhik Maas, the extra lunar month of Vaishakha, running from 15 April 2010 to 14 May 2010. Saraswati Puja (Vasant Panchami) fell on 20 January, 11 days earlier in the year than in 2009 - a lunar year runs about eleven days short of a solar one.

How many festivals and vrats does the Assamese Calendar list in 2010?
The Assamese Calendar lists 15 dates in 2010. The first is Uruka (Magh Bihu Eve) on Wednesday, 13 January 2010, and the last is Raas Mahotsav on Sunday, 21 November 2010.
What are the main festival dates in the Assamese Calendar for 2010?
The first major observances of 2010 are:
- Uruka (Magh Bihu Eve) - Wednesday, 13 January 2010
- Magh Bihu (Bhogali Bihu) - Thursday, 14 January 2010
- Saraswati Puja (Vasant Panchami) - Wednesday, 20 January 2010
- Maha Shivaratri - Friday, 12 February 2010
- Doul Utsav (Holi) - Sunday, 28 February 2010
- Bohag Bihu (Rongali Bihu) - Wednesday, 14 April 2010
Which traditional year does 2010 correspond to in the Assamese Calendar?
The Gregorian year 2010 spans Bhaskarabda 1416 – 1417. 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 2010 have an Adhik Maas?
Yes. 2010 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 2010 dates can look out of place beside a neighbouring year.
Were there any eclipses in 2010?
2010 had 5 eclipses:
- 1 January 2010 - Partial lunar eclipse (Chandra Grahan), visible in India, so Sutak Kaal was observed
- 15 January 2010 - Annular solar eclipse (Surya Grahan), visible in India, so Sutak Kaal was observed
- 26 June 2010 - Partial lunar eclipse (Chandra Grahan), visible in India, so Sutak Kaal was observed
- 12 July 2010 - Total solar eclipse (Surya Grahan), not visible from India
- 21 December 2010 - Total lunar eclipse (Chandra Grahan), not visible from India
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 2010?
Yes - 3 sign changes among the slow grahas in 2010:
- Guru (Jupiter) entered Meena on 2 May 2010
- Guru (Jupiter) entered Kumbha on 1 November 2010, moving retrograde
- Guru (Jupiter) entered Meena on 6 December 2010
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 2010?
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.
