Why 82^{\circ}30'E has been selected as the Standard Meridian of India?
82^{\circ}30'E has been selected as the Standard Meridian of India for the following reasons:
Central Location: It passes almost through the center of India (near Mirzapur in Uttar Pradesh), providing a uniform time for the entire country.
To Avoid Confusion: There is a time lag of two hours between Gujarat in the west and Arunachal Pradesh in the east. Selecting a central meridian ensures that watches show the same time across the nation, avoiding confusion in transport and communication.
International Standard: It is a multiple of
7^{\circ}30', which is a globally accepted standard for selecting time zones (representing a 30-minute time difference).
