Significance of Longitude 82°30'E in India's Time Zone
Birthplace of the Indian Standard Time (IST)
- The longitude 82°30'E passes through the city of Allahabad in India, which is known as the birthplace of the Indian Standard Time (IST).
- In 1905, the longitude passing through Allahabad was chosen as the official meridian for IST, making it the reference point for timekeeping across the country.
- This decision was made at the 25th meridian conference held in Washington DC in 1884, where it was decided to divide the world into 24 time zones, each 15 degrees of longitude apart.
Location of the Prime Meridian in India
- The Prime Meridian, which is the starting point for measuring longitude, passes through Greenwich, London.
- In India, the longitude 82°30'E is not the Prime Meridian but serves as the reference point for IST.
Dividing line between Northern and Southern Hemispheres
- The longitude 82°30'E does not serve as the dividing line between the Northern and Southern Hemispheres. This distinction is determined by the Equator, which is located at 0 degrees latitude.
Reference point for Indian Daylight Saving Time (IDST)
- Indian Daylight Saving Time (IDST) is not officially observed in India. Therefore, the longitude 82°30'E does not serve as the reference point for any daylight saving time adjustments in the country.
In conclusion, the significance of the longitude 82°30'E in India's time zone lies in its role as the birthplace of the Indian Standard Time (IST), serving as the official reference point for timekeeping across the country.
