The earth has 360 imaginary lines called longitudes or meridians running vertically between the poles. Each of these longitudes is called a degree. The 0 degree longitude passing through Greenwich, near London, is considered as standard and the time of all other time zones are calculated accordingly.
Example:-
If it is 12 noon at Greenwich,time in India:
We know that the time difference between 2 longitudes is 4 min. and IST is located at 82.5 longitude whereas that of Greenwich is 0 longitude.Hence,time difference = 82.5 * 4 = 330 min. or 5 hrs 30 min.
