Why large countries have many time zones?
As we all know, Earth rotates on its own axis, it takes about 24 hours for the Earth to complete one rotation, which is the duration of one day. Earth revolves around the sun and it takes almost 365 days to complete one revolution which is the time duration of one year. Earth is a very vast planet and to identify various places on it we take the help of Latitude and Longitude.
