Ratha Saptami also rendered Magha Saptami, is a Hindu festival that falls on the seventh day (Saptami) in the bright half of the Hindu month Magha.
It is symbolically represented in the form of the sun-god Surya turning his ratha (chariot) drawn by seven horses (representing the seven colors) towards the northern hemisphere, in a north-easterly direction. It also marks the birth of Surya and is hence also celebrated as Surya Jayanti (the sun-god’s birthday).
Ratha Saptami is symbolic of the change of season to spring and the start of the harvesting season. For most Indian farmers, it is an auspicious beginning of the New Year. The festival is observed by all Hindus in their houses and in innumerable temples dedicated to Surya, across India.
There are Surya temples all across India where Ratha Sapthami is fervently celebrated. However, the most famous one is the World Heritage Site of the Konarak Sun Temple, in Konark, Odisha. Besides Konark, there is another sun temple in Odisha, the Biranchinarayan Temple, Buguda, Ganjam District. There are sun temples in Modhera, Gujarat, created by king Bhimdev of the Chaulukya dynasty, in Arasavalli, Andhra Pradesh and in clusters of Navagraha temples in Tamil Nadu and Assam.
