The foundation of Hindu astrology is the notion of bandhu of the Vedas, (scriptures), which is the connection between the microcosm and the macrocosm. Practice relies primarily on the sidereal zodiac, which is different from the tropical zodiac used in Western  (Hellenistic) astrology in that an ayanamsa adjustment is made for the gradual precession of the vernal equinox. Astrology remains an  important facet in the lives of many Hindus. In Hindu culture, newborns are traditionally named based on their jyotish charts, and astrological concepts are pervasive in the organization of the calendar and holidays as well as in many areas of life, such as in  making decisions made about marriage, opening a new business, and moving into a new home. Astrology retains a position among the sciences in modern India.
The term jyotiṣa in the sense of one of the Vedanga, the six auxiliary disciplines of Vedic religion, is used in the Mundaka Upanishad and thus likely dates to Mauryan times. TheVedanga Jyotisha redacted by Lagadha dates to the Mauryan period, with rules for tracking the motions of the sun and the moon.

The documented history of Hindu astrology begins with the interaction of Indian and Hellenistic cultures in the Indo-Greek period. The oldest surviving treatises, such as the Yavanajatakaor the Brihat-Samhita, date to the early centuries CE. The Yavanajataka ("Sayings of the Greeks") was translated from Greek to Sanskrit by Yavanesvara during the 2nd century CE, under the patronage of the Western Satrap Saka king Rudradaman I, and is considered the first Indian astrological treatise in the Sanskrit language.

The first named authors writing treatises on astronomy are from the 5th century CE, the date when the classical period of Indian astronomy can be said to begin. Besides the theories ofAryabhata in the Aryabhatiya and the lost Arya-siddhānta, there is the Pancha-Siddhāntika of Varahamihira.

The main texts upon which classical Indian astrology is based are early medieval compilations, notably the Bṛhat Parāśara Horāśāstra, and Sārāvalī by Kalyāṇavarman. TheHorashastra is a composite work of 71 chapters, of which the first part (chapters 1–51) dates to the 7th to early 8th centuries and the second part (chapters 52–71) to the later 8th century. The Sārāvalī likewise dates to around 800 CE. English translations of these texts were published by N.N. Krishna Rau and V.B. Choudhari in 1963 and 1961, respectively. Historically, the study of astrology in India was an important factor in the development of astronomy in the Early Middle Ages. Ganaka is a caste in Kerala, India famous for doing traditional Hindu or vedic astrology as their traditional career.
