Tamil calendar
The Tamil calendar is one of the many traditional calendars in India. It is a solar calendar and is mainly used in the Indian state of Tamil Nadu and by the Tamils in Sri Lanka .
history
The oldest references to chronology on the Indian subcontinent can be found in the Vedas , the oldest parts of which date back to around 1200 BC. Go back BC. The Jyotisha Vedanga with treatises on astronomy and astrology comes from a later period . Greek and West Asian knowledge influenced the Siddhantas (astronomical textbooks) in the first centuries AD. Especially the Arya-Siddhanta and the Yakkya-Karana form the basis of the Tamil calendar.
The year
The year is a sidereal year . In the Surya Siddhantas the length is given as 365.2587558 days (365 days 6 hours 12 minutes 36.5 seconds); other Siddhantas deviate from it by a few seconds. The actual value is 365.256360 days ( 365 days 6 hours 9 minutes 9.5 seconds ).
The year count
The years are counted according to the Kali Yuga era and according to the 60-year Jupiter cycle , in which each year has its own name. The government has been using the Tiruvalluvar era since 1981 (partly since 1971) .
The names of the years in the 60-year cycle are:

The beginning of the year
The beginning of the year is determined by the entry of the sun into the zodiac sign mêsha (Aries). the year then begins with the month of Chittirai. In 2008 the beginning of the year was changed to the month of Tai, but this change was so controversial that it was reversed in 2011.
In the post-Thiruvalluvar era year count used by the government, the year continues to begin with the month of Tai.
If the sun enters these signs of the zodiac between sunrise (beginning of the day) and sunset, the year begins on the same day, if the sun enters this sign of the zodiac between sunset and sunrise (end of day), the year begins the next day.
The circuit
There is no fixed switching scheme for years with 366 days, as the beginning of the year is determined by the entry of the sun into the zodiac sign Aries. Whether a year has 365 or 366 days can be seen from the astronomical data. The next years with 366 days are:
Kali Yuga | Year in cycle | year | |
---|---|---|---|
tamil | German | Gregorian | |
5013 | நந்தன | nandana | 2012-2013 |
5017 | துன்முகி | durmukha | 2016-2017 |
5021 | சார்வரி | śarvarin | 2020-2021 |
5024 | சோபகிருது | śôbhana | 2023-2024 |
5028 | பிலவங்க | plavaṅga | 2027-2028 |
The precision
With 365.2587558 days, the Siddhanta year is 0.0023958 days (3 minutes and 26 seconds) longer than the sidereal year with 365.256360 days. This means that it will shift against the fixed star sky by one day in around 400 years. The Siddhanta year with 365.2587558 days is 0.01656528 days (23 minutes and 51 seconds) longer than the tropical year with 365.24219052 days. This means that in around 60 years it will be shifted by one day compared to the seasons. The year currently starts around 23 days after the spring equinox.
The month
The path that the sun apparently travels in a sidereal year is divided into 12 signs of the zodiac of 30 ° each. Since the earth's orbit around the sun is an ellipse, the sun stands for different lengths of time in the individual signs of the zodiac, as the following table shows:

The beginning of the month
The beginning of the month is determined by the entry of the sun into a new zodiac sign. If the sun enters the zodiac sign between sunrise (start of the day) and sunset, the month starts on the same day, if the sun enters the zodiac sign between sunset and sunrise (end of day), the month starts the next day.
The length of the month
During its apparent course, the sun stands for different lengths of time in the individual signs of the zodiac. The time varies between 29.34806 days (29 days 8 hours 21 minutes 12 seconds) and 31.61057 days (31 days 14 hours 39 minutes 13 seconds). Accordingly, a month lasts between 29 and 32 days, and a single month can have different lengths in different years.
The month names
The months were originally named after the Nakshatra lunar houses , where the sun entered a new zodiac sign. The months of the year have the following names and corresponding dates in the Gregorian calendar:
month | கர / khara (Thiruvalluvar 2041-2042) |
நந்தன / nandana (Thiruvalluvar 2042–2043) |
விஜய / vijaya (Thiruvalluvar 2043-2044) |
ஜய / jaya (Thiruvalluvar 2044–2045) |
