Tamil solar calendar
hello Long live Vaiyagam... Long live Tamil...
Tamil solar calendar developed based on the astronomical knowledge of Tamils, modern science. In this way, you can learn about sun, moon, star movements, climate and weather with Tamil as the primary language.

"The Veal's Mouth Mandilam spread by Viri Kadir
Two-goal marker position is not slippery
For half a day without a skill,
The rope of the scholar Muninith,
To God with them,
Make a plot for the king of great fame."
-[73 - 78], Nedunalvadai

Sun Movement - Birth Month,
Tamil months are calculated based on the movement of the sun.
The point where the Equator and the Sun Ecliptic meet is 0°00'01" and the Sun's arrival at Bagai is the first day of the month of Chitra. This day falls on March 20.3.2024. The current calendar we use is 25 days late. .This way every month is late by 25 days.This is called Nirayana method.I am predicting the solar calendar by Narayana method based on the movement of sun in the sky.

"30°00'01" is the first day of the month of Vaikasi, when the Sun arrives at Baga.
"60°00'01" is the first day of the month of Ani.
"90°00'01" is the first day of the month of Adi when the Sun arrives at Pagan.
The first day of the month of Awani is the day when the Sun arrives at "120°00'01".
"150°00'01" is the first day of the month of Puratasi when the Sun arrives at the declination.
"180°00'01" is the first day of the month of Ippasi when the sun comes into the path.
The first day of the month of Karthikai is the day when the sun sets at "210°00'01".
"240°00'01" is the first day of the month of March.
The first day of the month of Tai is the day when the sun sets at "270°00'01".
"300°00'01" is the first day of the month of Masi.
The first day of the month of Panguni is the day when the sun sets at "330°00'01".

Accordingly, the calculation of Tamil month of 30°00'00" bhagays for one month is correct according to the movement of the Sun.
Thank you and good bye. Long live Vaiyagam... Long live Tamil...
