Just like any other ancient traditional festivals, Ugadi has many scientific and astronomical bondages to it.

Nope, it’s not a new year, it indicates the changes in season in correspondence to the functioning of human body.


While other people who take after the Sauramana date-book, i.e states, for example, Tamil Nadu – Puduvarsham, Kerala – Vishu, Punjab-Baisakhi, Assam – Bohali Bihu, Sri Lanka and so forth commend the New Year ordinarily on April 14/15th as the day when Sun travels into Aries Zodiac.



A vast majority of India likewise takes a general Jovian system or Jupiter based system wherein years are taken in cycles of 60 years. i.e. 60 years have diverse names and once 60 years have passed, the 61st year gets an indistinguishable name from the principal year in the 60 year cycle. This 60-year cycle is known as a Manava Yuga.

Why a 60-year calendar?

The Earth revolves around the Sun in one year, and Jupiter takes 12 years to go around the sun, Saturn being the laziest takes 30 years for the same :P, The lowest common denominator, i.e. the earliest time when both Jupiter and Saturn can meet at the same position, with respect to the Sun, Moon, and Earth, is 60 years.
Hence this 60-year cycle or the 60-year calendar.

The sixty-year calendar cycle repeats itself and each of these years are named differently, which is said to denote some qualitative aspect of the year.

The 60-year cycle is also called as Manava Yuga because a person’s prime life is considered to be 60 years.

It is called Yuga, because, it is an alignment. An alignment of man on Earth, the Earth, the Moon, the Sun, Jupiter, and Saturn. Yuga comes from Jug or Yog which means union as in Yoga which is a union of body and mind.

Yug means an alignment of the astral bodies; which in turn denotes a period of time and Adi being the beginning.

Thus Yugadi, also popularly spelled as Ugadi, is the start of a period of time or Yuga.


Yuga or alignment here is the yearly alignment of the Earth’s equator with the Sun, the Moon and the Zodiac of Chaitra. This is why this New Year festival is called a Yugadi.

On this day (Ugadi) the earth’s axis is positioned in such a way that Northern hemisphere receives the highest amount of solar energy.


Speaking astronomical occurrences the day before Ugadi is Amavasya (New Moon).

Which entails the last day of the waning of Moon and the first day of waxing of the moon. Which connotes the start of new time.


According to our Indian great Mathematician Bhaskaracharya, the Sunrise on the day of Ugadi is the beginning of New Year because of the earth exactly complete it’s one revolution around the sun.


These seasonal changes entangle to the functioning of the body, which is explained by obvious medical issues like seasonal cases of flu, changes in the metabolism of the body etc.


Sri Vilambi Nama Samvatsara Subhakanshalu.
