Vedanga Jyotisha (IAST: Vedāṅga Jyotiṣa), or Jyotishavedanga (Jyotiṣavedāṅga), is one of earliest known Indian texts on astrology (Jyotisha).[1] The extant text is dated to the final centuries BCE,[2] but it may be based on a tradition reaching back to about 700-600 BCE.[3]
The text is foundational to Jyotisha, one of the six Vedanga disciplines.[4] Its author is traditionally named as Lagadha.[5][6][7]
