What is the difference between longitude and time?

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. The time difference between each longitude (each degree) is 4 minutes.

Similarly, you may ask, what is the relationship between the longitude and time?

Longitudes run from North to South,from 0 degrees(which passes through Greenwich(England) and sometimes called the Greenwich Meridian)to 180 degrees East or West. Generally 1 degree difference in Longitude, causes a difference of 4 minutes,with the longitude East always ahead in time.

How longitudes are used to calculate time?

Because one day is 24 hours long one can easily use time to calculate longitude. One hour of time difference corresponds to 15° of longitude (360°/24 hours = 15°/hour). Suppose an observer sets his accurate watch to 12:00 at noon in Greenwich, England and then travels a great distance.

How many longitude is in each timezone?

The time in each successive time zone is one hour different from the times in neighboring time zones. To establish time zones, Earth's rotation rate of 360 degrees of longitude per day was divided by 24 hours. The result shows that Earth turns 15 degrees of longitude per hour.
