Tamil calendar

The Tamil calendar is a solar and sidereal Hindu calendar used in Tamil Nadu. It is also used in Pondicherry (India), and by the Tamil population in Malaysia, Singapore, Mauritius and Sri Lanka. It is also used by Telugu speaking people in Tamil Nadu. It is used today for cultural, religious and agricultural events, with the Gregorian calendar largely used for official purposes both within and outside India. The Tamil calendar is based on the classical Hindu solar calendar also used in Assam, Bengal, Kerala, Manipur, Nepal, Orissa, Rajasthan and the Punjab.

There are several festivals based on the Tamil Hindu calendar. The Tamil New Year follows the nirayanam vernal equinox and generally falls on 13 or 14 April of the Gregorian year. 13 or 14 April marks the first day of the traditional Tamil calendar and this remains a public holiday in both Tamil Nadu and Sri Lanka. Tropical vernal equinox fall around 22 March, and adding 23 degrees of trepidation or oscillation to it, we get the Hindu sidereal or Nirayana Mesha Sankranti (Sun's transition into nirayana Aries). Hence, the Tamil calendar begins on the same date in April which is observed by most traditional calendars of the rest of India - Assam, Bengal, Kerala, Orissa, Manipur, Punjab etc. This also coincides with the traditional new year in Burma, Cambodia, Laos, Sri Lanka, Bangladesh Nepal and Thailand. The 60-year cycle is also very ancient and is observed by most traditional calendars of India and China, and is related to 5 revolutions of Jupiter according to popular belief, or to 60-year orbit of Nakshatras (stars) as mentioned in Surya Siddhanta.

The traditional Tamil year starts on 13 April 2012, Kaliyuga 5114. Vikrama and Shalivahana Saka eras are also used. There are several references in early Tamil literature to the April new year. Nakkirar, the author of the Nedunalvaadai writes in the 3rd century that the Sun travels from Mesha/Chitterai through 11 successive Raasis or signs of the zodiac.^[1] Kūdalūr Kizhaar in the 3rd century refers to Mesha Raasi/Chitterai as the commencement of the year in the Puranaanooru.^[2][3] The Tolkaapiyam is the oldest surviving Tamil grammar that divides the year into six seasons where Chitterai marks the start of the Ilavenil season or summer. The 8th century Silappadikaaram mentions the 12 Raasis or zodiac signs starting with Mesha/Chitterai.^[4] The Manimekalai alludes to the Hindu solar calendar as we know it today. Adiyaarkunalaar, an early medieval commentator or Urai-asiriyar, mentions the 12 months of the Tamil Hindu calendar with particular reference to Chitterai. There were subsequent inscriptional references in Pagan, Burma dated to the 11th century CE and in Sukhothai, Thailand dated to the 14th century CE to South Indian, often Vaishnavite, courtiers who were tasked with defining the traditional calendar that began in mid-April.^[5]

Week

The days of the Tamil Calendar relate to the celestial bodies in the solar system: Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn, in that order. The week starts with Sunday.

This list compiles the days of the week in the Tamil calendar:

For Tamils the each day begins at the sun rise. The evening of Thursday(the meeting point of Thursday and Friday) loans are to be eschewed during this period till Friday wanes off. In this regard Paruthimar Kalingar has done extensive research to prove the beginning of a Tamil day

Months

The number of days in a month varies between 29 and 32.

The following list compiles the months of the Tamil Calendar.

Note: The Sanskrit months above would start one month ahead of Tamil months since the Tamil calendar is a solar calendar while the Sanskrit calendar is a lunisolar calendar

Seasons

The Tamil year, in keeping with the old Indic calendar, is divided into six seasons, each of which lasts two months:

Sixty-year cycle

The 60-year cycle of the Tamil calendar is common to North and South Indian traditional calendars, with the same name and sequence of years. Its earliest reference is to be found in Surya Siddhanta, which Varahamihirar (550 CE) believed to be the most accurate of the then current theories of astronomy. However, in the Surya Siddhantic list, the first year was Vijaya and not Prabhava as currently used. This 60-year cycle is also used in the Chinese calendar.

After the completion of sixty years, the calendar starts anew with the first year. This corresponds to the Hindu "century." The Vakya or Tirukannitha Panchangam (the traditional Tamil almanac) outlines this sequence.

The following list presents the current 60-year cycle of the Tamil calendar:

Celebrations

The months of the Tamil Calendar have great significance and are deeply rooted in the faith of the Tamil Hindus. Some months are considered very auspicious while a few are considered inauspicious as well.

Some of the celebrations for each month are listed below. Dates in parentheses are not exact and usually vary by a day or two. Underneath (or beside) the months of the Hindu calendar are their Gregorian counterparts.

Significance

• The Hindus developed a system of calendrics that encapsulates vast periods of time. For computing the age of the earth and various geological and other epochs, as well as the age of mankind, they still employ a Tamil calendar derived from ancient astronomical data, known as the Tirukkanida Panchanga (cf. The Secret Doctrine, 2:49-51).

• This calendar contains a calculation of something over three hundred million years for the age of the present earth since sedimentation occurred, and a period of somewhat more than eighteen million years since the first appearance of our mankind.

• The 10th Tamil month, called Thai, falls in mid-January each year. It is celebrated with much enthusiasm within the Tamil Community all over the world. Thai is marked by gifts of new clothing for family members and prayers to God for prosperity in the coming year. Thai and the fifth month Aavani are considered very auspicious for marriage and most marriages occur during these months.

• The fourth month Aadi is considered inauspicious, so weddings do not often fall in this month. Aadi is also the month of preparation for the next crop cycle by farmers. Therefore, farming communities avoid major events like weddings in this month. Those members of the Tamil community who don't actively contribute/participate in farming take advantage by having important functions like wedding in this month. For example, the business community prefers this month for weddings. Asdi is usually the worst month for business, although when businesses recently initiated Aadi discounts, this situation has changed significantly. Each Friday of this month is set aside for prayer and worship.

• Aadi ia an inauspicious month for newlyweds to sleep together because a woman who conceives in this month will have a difficult delivery in May, the hottest month in Tamil Nadu (Agni natchathiram [pinezu] last 7 days of Chitharai and [munezu] first 7 days of Vaigasi).?)

• Purattaasi is when most of the non-vegetarian Tamil people fast from meat for a month. This faith can be considered similar to fasts undertaken by Muslims during Ramadan. Each Saturday of this month is set apart to venerate the planet Saturn.

• Deepavali, is celebrated on the new moon day, in the seventh month Aipassi. The month of Aipassi is usually characterised by the North-East Monsoon in Tamil Nadu, which has given birth to a phrase, Aipassi Adai Mazhai meaning the "Non-stop Downpour".

• Maargazhi falls in winter in Tamil Nadu, and is considered auspicious for unmarried women to find a groom. The Shaivite fast of Tiru-vembaavai and the Vaishnava fast of Tiru-paavai are also observed in this month.

• The total number of days in a Tamil Calendar is an average 365 days and the days of the week are named similarly to those of the western calendar. The Vakiya Panchangam is employed for both sacred and civil calculations. The Trikanitha Panchangam is employed for astrological calculations.

Festivals

The Tamil Calendar is so important to the life of Tamil-speaking people that most of the Festivals of Tamil Nadu are based on it. Some of Festivals include Tamil New Year or Puthandu in mid-April, Thai Pongal, Deepavali, Panguni Uthiram, Thirukaarthigai, Aadiperukku, Navaratri etc.
