The idea that “Nobody can stop an idea whose time has come” reflects the timely relevance of introducing two time zones in India.

• India has achieved sufficient economic, educational, technological, and logistical maturity to adopt this reform.

Recent Government Signals Support Change

• At the Rising Northeast Investors Summit 2025, PM Modi emphasized EAST as an acronym for Empower, Act, Strengthen, Transform.
• NITI Aayog, during discussions for Viksit Bharat @2047, encouraged states to leverage unique geographic and demographic advantages.

Current Dilemma: Sunrise Disparity and Wasted Potential

• IIndia’s longitudinal span, extending from 68°7′ in the West (Gujarat) to 97°25′ in the East, with the spread of 29°results in a natural time difference of over two hours from the geographic perspective.
• However, the entire country adheres to a single IST, set at 82.5°E longitude, which passes through Mirzapur, Uttar Pradesh. This standard is approximately 5.5 hours ahead of Greenwich Mean Time (GMT).
• Due to India’s single time zone (IST), eastern and northeastern states cannot fully utilize their early sunrise. 

Consequences of Single Time Zone

• Wasted Daylight Hours: In the East, the sun rises considerably earlier than the clock indicates, based on IST. This leads to a substantial loss of valuable daylight hours.
• Productivity Loss: The misalignment between natural daylight and official working hours results in significant productivity losses. 
  • For example, tea gardens in the Northeast already operate on a separate “Chai Bagan Time Zone,” which is one hour ahead of IST, to better utilise daylight and maintain productivity.
• Energy Inefficiency: With early sunrises and sunsets in the East, operating on IST means that evening activities often require artificial lighting, leading to increased power consumption.

Historical Precedent and Previous Objections

• Historically, British India recognised these geographical realities and operated with multiple time zones. 
• In 1884, Calcutta Time (based on the 90th meridian east) and Bombay Time (based on the 75th meridian east) and Madras Time were in use. 
• Calcutta Time was 23 minutes and 20 seconds ahead of IST and 1 hour, 2 minutes, and 20 seconds ahead of Bombay Time. 
• Calcutta and Bombay regional time zones continued until 1948 and 1955, respectively.

Reasons For Adoption Of Single Time Zone

• The move to a single time zone was driven by arguments for administrative simplicity and to avoid confusion, especially concerning railway schedules, banking, and government timings.
• The Railways, as the primary provider of long-distance connectivity, was particularly vocal in its opposition to multiple time zones due to operational challenges. 
• Additionally, low literacy rates at the time were cited as a reason for potential public confusion.

Arguments for Implementing Two Time Zones At Present Time

The objections raised in the mid-20th century are largely irrelevant today. A strong case for two time zones is built upon several critical factors:

• National Maturity: India’s significant progress in economic growth, education, technology, and logistics since 1947 indicates a readiness to manage the complexities of multiple time zones effectively.
• Enhanced Productivity: Adopting two time zones would allow eastern and northeastern states to better leverage their early sunrise, saving crucial daylight hours and preventing substantial productivity losses. This would significantly impact the national GDP, particularly benefiting the agri-economy that naturally follows the sun’s rhythm.
• Significant Energy Savings: A study by organizations like Prayas (Pune-based non-profit) and Motilal Oswal indicates that operating with two time zones could lead to a 10% reduction in the planned 80 GW thermal capacity, saving approximately ₹7,000 crore in capital expenditure.
  • Recurring energy consumption savings are estimated between 7.5% and 10%.
  • This rationalisation of energy consumption aligns with broader economic and environmental goals.
• Biological and Social Well-being: Aligning time zones with natural daylight cycles supports individuals’ biological circadian rhythms, which regulate sleep and wakefulness, thereby improving overall well-being. It also ensures that citizens in the East can access government, business, and civic services within their natural diurnal life.
• Improved Civil Aviation Utilisation: Studies, including those by the Ministry of Civil Aviation, suggest that a two-time-zone system with a one-hour difference could increase aircraft utilisation by 20%. This is a critical gain given the current fleet shortages.
• Technological Advancements and Higher Literacy: The argument of “confusion” due to multiple time zones no longer holds. Ubiquitous electronic gadgets automatically adjust time zones.
  • India’s literacy rate stands at 78%, which is comparable to the global average of 86%. The population is capable of adapting to such a change with gradual adjustment.
• Global Precedents: Many countries worldwide successfully manage multiple time zones. Indonesia, for instance, with a longitudinal difference of 46°, operates on three time zones.
  • France has multiple time zones, and several nations manage seasonal time standards for daylight saving. 
• Economic Opportunities: A smaller time difference could help re-establish Kolkata as a leading financial market, potentially competing with other Asian hubs like Singapore and Hong Kong.

Conclusion

It is recommended that an inter-ministerial task force be constituted under the Prime Minister’s Office, with active participation from NITI Aayog, to thoroughly examine and implement the proposition of introducing at least two time zones for the country. This is a crucial step towards fostering a more efficient, productive, and well-adjusted India.
