Ratha Saptami or Rathasapthami (), also rendered Magha Saptami, is a Hindu festival that falls on the seventh day (saptami) in the bright half (Shukla Paksha) 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 colours) towards the northern hemisphere, in a north-easternly direction. It also marks the birth of Surya and is hence also celebrated as Surya Jayanti (the sun-god’s birthday).
