The word "Vishu" itself comes from Sanskrit,
meaning "equal," and the festival celebrates the vernal equinox, when
day and night are roughly equal in length. It marks the first day of the
astronomical year and is a celebration of new beginnings, hope, and prosperity.
Vishu has both astronomical and mythological significance:
Astronomically, it marks the sun's entry into Aries,
beginning a new solar cycle. It is also considered an auspicious day for
farmers, as it marks the beginning of a new agricultural cycle — the belief
being that a good harvest in the coming year depends on how the first day of
the year goes.
Mythologically, one significance is that on this day, Lord
Krishna killed the demon Narakasura, and the festival is celebrated to mark his
victory. Lord Vishnu is worshipped as the "God of Time," and Krishna
idols are prominently displayed during the celebrations.
A change of calendars 1201 years ago
In 825 CE, Kerala (or the region that’s now Kerala) switched
to a different calendar (which is also a solar sidereal calendar) for which the
first month is Chingam and New Year in this calendar (the 1st of Chingam) falls
around August 17. The Kollam Era calendar is the one more widely used today for
official and everyday purposes in Kerala, which is why many Malayalees also
consider Chingam 1 a new year of sorts. But Vishu's roots lie in the older
solar sidereal calendar where Medam comes first.
Why did Kerala (for want of a better way of describing the region that’s now Kerala) switch from one calendar to another? There are various theories.
1. The most popular
theory is that in the year 825 CE, a great convention in the town of Kollam
(which was called Quilon
by the British, which continued until 2012) at the behest of King
Kulashekhara Varman, who was the Chera king. At the convention, the
Kollavarsham calendar was commenced by royal decree passed by Udayamarthanda
Varma, the local ruler at whose seat (Kollam) this convention took place.
According to one scholar, Kollavarsham also marked a political transition —
from the reign of the Perumals to a new caste-based rule. The commencement of
Kollavarsham was, in
this view, a declaration of political and cultural change in Kerala.
2. A second
theory (propounded by Hermann Gundert) is
that Kollavarsham started as part of erecting a new Shiva Temple in Kollam, and
because of the strictly local and religious background, other regions did not
follow this system at first. Once the Kollam port emerged as an important trade
center, however, other regions also started to follow the new calendar system.
3. A third
theory links the calendar's origin to the birth of the great philosopher
Adi Shankaracharya, whose
birth has been dated to around 825 CE by some accounts.
4. It has also been theorised that the new era commemorated
the foundation of Kollam by Maruwan
Sapir Iso, leader of Persian Christian settlers and trading guilds, following
the liberation of the Kingdom of Venad from Chola rule.
In any event, the rise of Kollam as a major international
port played a big role in spreading the new calendar. As merchants from Persia,
China, and the Arab world converged on Kollam, having a locally standardized
calendar likely served practical administrative and commercial purposes.
Tamil New Year and Vishu: Any difference?
The old Malayalam calendar was the same as the current Tamil
calendar, which hasn’t undergone any change since the Sangam period when records
began to be kept. Both were solar sidereal calendars with the same core
principles:
- Months
are defined by the Sun’s transit into each sidereal zodiac sign
(Rashi/Sankranti).
- The
New Year begins on Mesha Sankranti (Sun entering Aries/Mesha Rashi), which
marks Medam 1 in Malayalam nomenclature or Chithirai 1 in Tamil.
- This
is the same astronomical event that traditionally started the year in both
regions.
In most years, the Tamil New Year falls on the same day as
Vishu. However, in 2026, the Tamil New Year will be celebrated on April 14th
and Vishu will be commemorated on April 15th. This gap of one day in 2026 highlights
a practical, regional nuance rather than a fundamental calendar difference:
In 2026, the Mesha Sankranti
moment occurs on Tuesday, April 14 at approximately 9:39 AM IST (exact timing
varies slightly by panchang, but generally mid-morning). Tamil tradition takes
the day of the Sankranti itself as the New Year, regardless of the exact hour
(as long as it falls after sunrise). In current Kerala/Malayalam panchang
practice, when the Mesha Sankranti moment occurs after sunrise, the festival
day is the next sunrise for Vishu Kani preparations and rituals. This is
not a “calendar split” between Tamil and old Malayalam systems — it’s a modern
observance convention difference between Tamil Nadu’s panchangs and Kerala’s
for the same underlying astronomical event.
What is a solar sidereal calendar?
Sidereal comes from the Latin word sidus, meaning
“star” or “constellation.” In astronomy and timekeeping, “sidereal” refers to
any measurement or cycle that is calculated relative to the fixed stars in the
sky, rather than relative to the Sun or the seasons. Imagine the sky has a
huge, fixed “star map” (the constellations of the zodiac). A sidereal period is
the time it takes for the Sun, Moon, or a planet to return to the exact same
spot against that fixed star background. This is different from tropical (or
“solar-seasonal”) measurements, which are tied to the Sun’s position relative
to Earth’s equator and the changing seasons (equinoxes and solstices).
A digression: What about the rest of India?
The majority of Indian communities follow lunar or lunisolar
calendars. The purely solar calendars of Kerala and Tamil Nadu are an exception
to the rule in India.
The main lunisolar calendars followed in India are the
following:
1. Vikram Samvat is the most
widely used calendar in India. It is a lunisolar calendar using twelve lunar
months and an intercalary month each sidereal year. Its epoch is 57 BCE and is
used across northern and western India, and is the official calendar of Nepal.
Rajasthan, Gujarat, Madhya Pradesh, Uttar Pradesh, Punjab, and Himachal Pradesh
all follow variants of this. The Sikh community also follows this calendar.
2. Shalivahana Shaka is popular in the Deccan
region of southern India and forms the basis for India's official national
calendar. It is followed in Maharashtra, Goa, Karnataka, Andhra Pradesh, and
Telangana. Their new year — called Ugadi by Kannadigas and Telugus —
falls on the new moon of the lunar month of Chaitra, typically in March or
April.
3. Bengali Calendar is used in West Bengal and
Bangladesh. It gives rise to the Bengali new year Poila Boishakh in
mid-April.
4. Odia, Assamese, and Maithili calendars: It
is used in Odisha, Assam, and Bihar/ Jharkhand respectively.
The Muslims follow a purely lunar calendar — the Islamic
Hijri calendar — with no intercalary months to sync with the solar year, which
is why Ramadan and Eid migrate through all seasons over a 33-year cycle.
Early Buddhist communities adopted the ancient Vedic
calendar and Buddhist festivals continue to be scheduled according to a lunar
system. Similarly, ancient Jain traditions follow the same lunisolar system as
the Hindu calendar for festivals and inscriptions.
Further digression: How Lunisolar Calendars Work
The Hindu lunisolar calendar is based on lunar months
corresponding to the phases of the moon. In one year, there are twelve months
of 29.5 days, accounting for a total of 354 days. The shortfall means that the
date of each festival moves back 11 days each year. To rectify this, an extra
"leap month" — called an Adhik Maas or Purushottam Maas
— is added about once every three years. This is how the calendar keeps
festivals roughly anchored to the same season year after year.
Within each month there are two fortnights called pakshas
("wings"), based on the waxing and waning of the moon. The waning
moon fortnight is called Krishna paksha (dark fortnight) and the waxing
moon fortnight is called Shukla paksha (bright fortnight). Each half
contains 15 lunar days called tithis. Some observant Hindus fast on the
11th day (Ekadashi) of each fortnight.
There's also a regional split within lunisolar systems:
regions following the Amavasyanta (or Amanta) calendar conclude each
month on the new moon day, followed primarily in southern and eastern India,
while the Purnimanta calendar ends the month on the full moon day,
followed mostly in northern and northwestern states.
Back to Kerala and Vishu: How is Vishu celebrated in
Kerala?
This is the heart of Vishu celebrations and the most
important ritual.
- The
night before Vishu, the elders of the house carefully arrange a
traditional brass vessel (uruli) or tray with auspicious items
symbolizing abundance.
- At
dawn (often before sunrise), family members (especially children) are led
blindfolded into the prayer room. They open their eyes to see the “Vishu
Kani” first, ensuring the year begins with prosperity and positivity.
Typical items in a traditional Vishu Kani include:
- A
lit nilavilakku (traditional oil lamp)
- Idol
or picture of Lord Krishna (or Vishnu)
- Golden
shower flowers (Kani Konna / Cassia fistula)
- Raw
rice, coconut (split), golden cucumber, lemon, jackfruit, mango, banana
- Mirror
(Aranmula kannadi or ordinary mirror)
- Coins,
gold ornaments, betel leaves, arecanut
- Fresh
paddy sheaves and turmeric
2. Vishu Kaineetam
After viewing the Kani, elders (usually grandparents or parents) give money or small gifts to children and younger family members. The amount traditionally ends in “1” (e.g., ₹11, ₹51, ₹101) as a symbol of good fortune. New clothes (Vishukodi) are also gifted.
3. Feasting – Vishu Kanji & Vishu Sadya
Food plays a big role:
- Morning:
Many families start with Vishu Kanji (a special rice porridge) or Vishu
Katta (a steamed rice cake).
- Lunch:
The grand Vishu Sadya—a vegetarian feast served on a banana leaf.
It includes rice, sambar, aviyal, olan, erissery,
thoran, pachadi, kichadi, pappadam, and
payasams (especially ada pradhaman or chakka pradhaman).
Bitter-sweet dishes like mango pachadi and neem preparations symbolise
life’s mixed experiences.
4. Other Traditions
Fireworks (Vishu Padakkam): Children and families
burst crackers and sparklers, especially in the evening, adding joy and noise
to the celebrations.
Temple Visits: Devotees flock to temples (especially
Guruvayur Sri Krishna Temple, Sri Padmanabhaswamy Temple in Thiruvananthapuram,
or local Krishna temples) for special poojas and to see the temple’s own Vishu
Kani.
Family Time & New Beginnings: People wear new clothes, exchange greetings, and many consider it auspicious to start new ventures or make important decisions on this day.
Wishing you a prosperous Vishu filled with joy, good food,
and bright beginnings! 🌼✨
