The Ujjayinī Prime Meridian is an imaginary line that passes through the town of Ujjain in Madhya Pradesh, India. It is historically significant as it was used by ancient Indian astronomers to measure time and determine the position of celestial bodies. Ujjain was an important center for astronomy in ancient India, and the meridian passing through it helped in the calculation of local time for that region. While the modern Prime Meridian is located at 0° longitude (passing through Greenwich, England), the Ujjayinī Prime Meridian reflects the early contributions of Indian scholars to the field of geography and timekeeping.
