Why Y East has been selected as the standard meridian of India?

Y East, or 82.5 degrees East longitude, was selected as the standard meridian of India to provide a uniform time reference across the country. This choice ensures that the entire nation operates on Indian Standard Time (IST), which is 5 hours and 30 minutes ahead of Coordinated Universal Time (UTC+5:30). The location is approximately in the center of India, minimizing time discrepancies across different regions. This standardization facilitates better coordination in transportation, communication, and administration.
