Everything you need to know about this 30-hour time format watch

Indian chronology is the world’s oldest, accurate, error-free and reliable method. ‘Vikramaditya Vedic Clock’, inaugurated by Prime Minister Narendra Modi, invented by Aaroh Shrivastava and created by Maharaja Vikramaditya Shodh Peeth and Ujjain Municipal Corporation, at a cost of around Rs 1.70 crore, restores the Vedic traditions of India. Through its use, it may be possible to restore Indian chronology with advanced modern technology by questioning the parameters of international timekeeping.

The thirty-hour time format – muhurat – is mentioned in the Rig Veda and other ancient texts. This time format is calculated from one sunrise to the next. There are 30 hours (muhurta), 30 minutes (kaal) and 30 seconds (kastha) between two sunrises. These texts are famous in Vedic astrology and deal with the division of time in Muhurtas for astrological and auspicious activities.

“The establishment of a Vedic clock in Ujjain would be important for several reasons that are deeply rooted in cultural, historical and astronomical contexts. Ujjain has a rich history of astronomy and astrology. It is home to the Jantar Mantar Observatory, which showcases ancient Indian astronomical instruments. The Vedic clock, which is likely based on principles derived from ancient Indian astronomy, could be evidence of the advanced astronomical knowledge of the ancient Indians. In Indian tradition, time is not just a measure but also a concept deeply linked to spirituality and cosmic order,” says Dr Ghanshyam Ratnani, a researcher.

At the time of the invention of the mechanical clock, the 24-hour system was adopted and the entire system was developed taking into account this technology. Our calendar, currently used worldwide, is solar, based on one complete solar cycle.

Local Mean Time (LMT) is derived by correcting apparent solar time for irregularities in the Earth’s orbit and rotation, which cause variations in the length of a day throughout the year. With the advancement in technology, this problem can be solved as we can count the sunrise and develop technology that can predict the same perfectly as done by Vedic Digital Clock.

“It would serve as an educational tool, helping people understand the principles of ancient Indian astronomy and timekeeping methods. Such an installation could boost tourism in Ujjain and attract both domestic and international visitors interested in history, culture and science. It could facilitate research in the field of ancient Indian astronomy and its relevance in modern times,” said Dr Sarvesh Sharma, a research fellow.

How the clock works

This timekeeping device calculates time using the latest technologies such as the Internet, GPS and satellites. The day of this clock changes when the sun rises, 00:00 means sunrise and date change. This clock is based on the Alternative Time Theory, a modern explanation of Muhurta mentioned in Vedic texts.

Vedic Clock currently works as a software, the calculations on which the software runs are derived using Nautical Almanac using Sunrise calculations. A formula has been introduced for perfect coordination with the Sun: Vedic Standard Time = 1.25 (LMT-Sunrise).

This formula is tried and tested. It demonstrates the correct functioning of the Muhurta cycle every day. The formulation and working of the time system has been verified by several expert masters in this field such as Wakankar Observatory, Dongla, Mahidpur (Ujjain district), Vikram University, Ujjain, Padma Shri nominee Dr. Bhagwatilal Rajpurohit from Ujjain and other people from the field.

“The establishment of a Vedic clock in Ujjain could serve as a bridge between the past and the present, connecting people to their cultural heritage while providing educational, economic and scientific benefits,” said Ram Tiwari, director of Maharaja Vikramaditya Shodh Peeth.


No varying sunrise time. 00:00 is the time of sunrise in every place.

Makes the work culture in the local city more systematic regarding nature.

Billions of units of electricity saved.

Saving a large amount of electricity will strengthen the places with scarcity of electricity and save a lot of natural resources, which will also control the pollution caused by generating electricity.

By using this time system the world will have three formats for global coordination UTC, for country coordination the capital becomes the center and for larger countries LMT can be implemented with the help of education and technology.

“People interested in history, culture and science would benefit from learning and experiencing the Vedic clock. Historians, astronomers and scholars studying ancient Indian science and technology would have a new source for their work. Increased tourism and interest in ujjain could boost the local economy,” said Pratik Khedkar, adventurer.

About the inventor

Aaroh Shrivastava B.Tech (Mechanical) went to England for further studies. He subsequently joined the merchant navy. He says: “The 24-hour time zone was established by the Egyptian civilization. France made the first clock sometime in the 14th to 16th centuries. England and the East India Company promoted this clock worldwide. However, Indian civilization had been aware of the time zone for 5000 years. Since the sun rises at different times every day, it was quite difficult to measure time mechanically. After thorough research and experimentation, I finally prepared the digital clock for the advanced time format and that was in fact in practice during the Vedic era. Later, I got a patent at that time and to promote my invention I took a cycle tour of twelve Jyotirlinga temples and Chaar Dham of the country, covering a distance of about 9000 km.
