Thai Pongal is a Tamil harvest festival. Thai Pongal is a four day festival which according to the Gregorian calendar is normally celebrated from January 13 to January 16. The day marks the start of the sun’s six-month-long journey northwards (the Uttarayanam). This also corresponds to the Indic solstice when the sun purportedly enters the 10th house of the Indian zodiac Makara or Capricorn. Thai Pongal is mainly celebrated to convey appreciation to the Sun God for providing the energy for agriculture.
