Answer: A standard meridian is crucial for India and the world because it helps establish a common reference point for timekeeping and coordination. 

• Uniform Time: A standard meridian helps maintain a uniform time across a vast country like India. Without a standard meridian, different regions would have their local times, leading to confusion and logistical challenges.
• Time Zones: India spans across two time zones, but using a single standard meridian (82.5 degrees East) for the entire country simplifies time management and administration.
• Global Coordination: Standard meridians are essential for international communication and coordination, ensuring that countries worldwide can synchronize their activities, such as trade, travel, and telecommunications.
• Railways and Transportation: Standard time facilitates scheduling and coordination for transportation systems like railways and airlines.
• Economic Activities: It aids in the organization of economic activities, such as banking and financial transactions, which rely on accurate and synchronized time.
