The term "Vedic astrology" occurs in occasional usage during the 1960s and 1970s, but it only enters common usage from the 1980s in self-help publications on Ayurveda or Yoga. "Vedic astrology" appears as a name for Hindu astrology in dedicated works on the topic from the 1990s, beginning with David Frawley's Astrology of the Seers - A Comprehensive Guide to Vedic Astrology
(1990), followed by numerous other authors.
By the 2000s, the term had become a common synonym for Jyotisha in astrological literature. It also acquired considerable public exposure in 2001 when it was widely discussed in the media, during the controversy over the Government decision to promote the teaching of "Vedic Astrology" in Indian universities. The term replaces "Hindu astrology", which had been in use as the English equivalent of Jyotisha since the early 19th century. - Wikipedia.
