  • Prime Minister Narendra Modi virtually inaugurated the Vikramaditya Vedic Clock in Ujjain, Madhya Pradesh.
  • The clock is mounted on an 85-foot tower within Jantar Mantar in Ujjain.


Indian 'Panchang' Based Timepiece

  • The clock is based on the Indian ‘panchang’ (almanack), offering a unique timekeeping system.
  • It provides information on planetary positions, Muhurat, astrological calculations, and more.
  • Additionally, it indicates Indian Standard Time (IST) and Greenwich Mean Time (GMT).

Historical Significance of Ujjain

  • Ujjain is historically significant for time calculation, with the standard time of the world determined from Ujjain 300 years ago.
  • The city is considered a center for time calculation, and the Tropic of Cancer passes through it.

Features of the Vedic Clock

  • The clock not only indicates time but also provides details such as moon position, Parva, Shubhshubh Muhurat, Ghati, Nakshatra, and more.
  • It aims to restore the tradition of Indian time calculation based on astronomical theories.

Operational Details

  • The Vedic clock operates by calculating time from one sunrise to another, dividing the period into 30 parts, where each hour consists of 48 minutes according to ISD.
  • It starts at 0:00 with the sunrise and functions for 30 hours.

Greenwich Mean Time (GMT)

  • Greenwich Mean Time is the mean solar time at the Royal Observatory in Greenwich, London. It serves as the benchmark for timekeeping


  • GMT was established in the 19th century when the Royal Observatory was designated as the prime meridian (0° longitude), dividing the Earth into Eastern and Western Hemispheres.

Time Zone:

  • GMT is often used synonymously with Coordinated Universal Time (UTC), although there are slight differences between the two.
  • GMT is primarily observed in the United Kingdom during the winter months, while British Summer Time (BST) is used during the summer.

Role in Timekeeping:

  • GMT serves as the reference point for coordinating time across different time zones worldwide.
  • It's commonly used in aviation, maritime navigation, and international telecommunications to establish a universal standard for timekeeping.


  • GMT is converted to local time in various regions by adding or subtracting the appropriate number of hours, based on their time zone relative to Greenwich.
  • For example, Eastern Standard Time (EST) is GMT-5, meaning it's five hours behind GMT.


  • GMT is of historical significance as the standard timekeeping reference established by the International Meridian Conference in 1884.
  • It's crucial for global communication, ensuring consistency in schedules, appointments, and international transactions.

Modern Usage:

  • While GMT remains relevant, it has been largely replaced by Coordinated Universal Time (UTC), which is more accurately regulated by atomic clocks.
  • However, GMT still holds significance in various fields, especially in historical contexts and traditional timekeeping practices.


With its unique features and historical significance, the clock stands as a symbol of India's rich cultural heritage and scientific advancements.
