Ratha Saptami or Rathasapthami (lang-sa????????, Telugu: ?? ??????, Kannada (Kannada language):????????) or Magha Saptami is a Hindu festival that falls on the seventh day (Saptami) in the bright half (Shukla Paksha) of the Hindu month Maagha. It marks the seventh day following the Sun?s northerly movement (Uttarayana) of vernal equinox starting from Capricorn (Makara). It is symbolically represented in the form of the Sun God Surya turning his Ratha (Chariot) drawn by seven horses (representing seven colours) towards the northern hemisphere, in a north-easterly direction. It also marks the birth of Surya and hence 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.
