Vikramaditya Vedic Clock installed on an 85 feet high tower near the Government Jiwaji Observatory inside Jantar Mantar in Ujjain, was recently inaugurated by Prime Minister Narendra Modi. 

World’s first Vedic Clock

Vikramaditya Vedic Clock is the world’s first clock that calculates time according to Indian Panchang (a time calculation system). Ujjain is regarded as the centre for time calculation as the Tropic of Cancer passes through the city. 

This Vedic Clock calculates time based on the Vedic Hindu calendar, planetary positions, Muhurta (auspicious timings), astrological calculations, solar eclipses, lunar eclipses, and other celestial events. It integrates these elements to display time according to Vedic principles. 

30-hour timeframe

Vedic Clock also displays Indian Standard Time (IST) and Greenwich Mean Time (GMT). It also calculates time based on the duration from one sunrise to the next. In this clock, the duration between two sunrises is divided into 30 parts, resulting in each hour consisting of 48 minutes. The clock operates within the timeframe of up to 30 hours from one sunrise to the next.

Ujjain city is home to India’s oldest observatory, constructed by Sawai Jai Singh II of Jaipur during the 18th century. Historically, the city enjoyed importance as the first meridian of longitude according to Hindu astronomical belief.
