Standard Meridian of India
India does not have a standard meridian of its own. However, the country follows the Indian Standard Time (IST), which is based on the 82.5° E longitude, passing through the city of Allahabad.

Significance of 82.5° E Longitude
- The 82.5° E longitude was chosen as the reference point for IST as it is almost midway between the western and eastern extremities of India.
- It is geographically convenient as it minimizes the time difference across the country.

Indian Standard Time (IST)
- IST is the time observed throughout India and Sri Lanka, with a time offset of UTC+5:30.
- It is maintained by the Council of Scientific and Industrial Research's National Physical Laboratory in New Delhi.

Time Zones in India
- India is spread across two time zones: UTC+5:30 in the western part and UTC+5:30 in the eastern part.
- The 82.5° E longitude serves as the reference point for both time zones.

Impact on Daily Life
- Having a standard time zone for the whole country simplifies communication, transportation, and scheduling of events.
- It ensures uniformity in timekeeping across the nation.

Conclusion
In conclusion, while India does not have a standard meridian of its own, the 82.5° E longitude serves as the reference point for the Indian Standard Time. This uniform time zone system plays a crucial role in various aspects of daily life in the country.
