Dating mathematics


Astronomy, astrology, mathematics , and religion were closely linked in ancient India. Astronomy developed out of the need to determine solstices, equinoxes, and phases of the moon for Vedic rituals. Eighteen early astronomical texts or siddhantas, of which only the Surya-Siddhantha , written around 400 BCE, survives, discuss topics including lunar and solar eclipses, astronomical instruments, and the phases of the moon. The Vedanga Jyotisha composed by the astronomer Lagadha about 500 BCE outlines a calendar based on a five-year cycle or yuga with 62 lunar months and 1,830 days. India's earliest calendar, the Saptarshi calendar is broken into 2,700-year cycles and a version counting back to 3076 BCE is still in use in parts of India today.
