My family and I would like to wish all Tamils a very Happy Tamil New Year. I sincerely hope and pray that this new year would bring loads of happiness and wealth to all. My new year wish would be for all Malaysians, especially Malaysian Indians, to prosper and enjoy a peaceful life.
Meanwhile today is Vaisakhi, the New Year for Sikhs. I take this opportunity to wish all Sikhs a very happy new year celebration.
Below I have attached an introduction to the origins and significance of the New Year picked up from Wikipedia. Please feel free to read through for knowledge. Thank You.

The Tamil New Year follows the Nirayanam vernal equinox and generally falls on April 14 of the Gregorian year. April 14th 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 with the same date which is observed by most traditional calendars of the rest of India as in Assam, Bengal, Kerala, Manipur, Orissa, Punjab etc not to mention Nepal, Burma, Cambodia, Laos, Sri Lanka and Thailand.
The 60-year cycle is also 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 is (from April 14, 2009), Kaliyuga 5111. Vikrama and Shalivahana Saka eras are also used. But in Tamilnadu, from the year 2009 the tamil new year was celebrated on the first day of Thai (usually January 14) by supporters of the DMK and affiliated political parties.
Tamil people celebrate Tamil new year on April 14. There are several references in early Tamil literature to the April new year. Nakkirar, the author of the Nedunalvaadai mentions in the 3rd century that the Sun travels from Mesha/Chitterai through 11 successive Raasis or signs of the Zodiac. Koodaloor Kizhaar in the 3rd century refers to Mesha Raasi/Chitterai as the commencement of the year in the Puranaanooru.
The 8th century Silappadikaaram describes the 12 Raasis/zodiac signs starting with Mesha/Chitterai. The Manimekalai alludes to the Hindu solar calendar as we know it today.
