The answer to this question is very simple. As we now know that the time zone is calculated based on the longitudes, some countries have a very large area so it is evident that many longitudes pass through the countries. Earth is divided into 24 Time zones so a large country can be part of multiple time zones.
Why do countries like USA and Canada have multiple time zones?
Large countries like U.S.A,Canada, Australia and Russia have many time zones because they have a large width and a vast East to West extent. Russia has as many as 11 time zones and USA has six zones.
Why does Canada have so many time zones?
The size of Canada is mainly one of the reasons why it has multiple time zones. When you look at the map, Canada stretches from 52 degrees to 141 degrees west, and one time zone is only 15 degrees wide, which means that it covers six different time zones.
Why are there many standard time in the countries like Russia and Canada?
Large countries like Russia Canada and the United States have vast longitudinal extent. They do not have a single Standard Time for the whole Country. They have many time zones with each time zone covering about 15° of longitude. The erstwhile Soviet Union had 11 times zones to cover 165° of longitudinal extent.
Why does USA have 5 timezones?
That year, five time zones were officially adopted as the US entered World War I: the Eastern, Central, Mountain, Pacific, and Alaskan zones still in use today.
Why are there multiple time zones?
As Earth turns by 15° around its axis, time changes by one hour; a 360º-degree rotation yields 24 hours. As a result, the world is divided into 24 time zones shifted by one hour each.
Why do a country have different time zones?
As the planet rotates, some places receive sunlight or darkness, resulting in day and night. As the Earth rotates into the sunlight, you’ll see the sunrise, whereas rotating out of the sunlight is where you see the sunset. The Earth’s rotation is the primary cause why countries follow different time zones.
Why there are 4 time zones in USA?
With so many time zones, different railroad lines were sometimes on different time systems, and scheduling remained confusing and uncertain. Finally, the railway managers agreed to use four time zones for the continental United States: Eastern, Central, Mountain, and Pacific.
Which country has the most time zones in the world?
Countries are ranked by total number of time zones on their territory. Time zones of a country include that of dependent territories (except Antarctic claims). France, including its overseas territories, has the most time zones with 12 (13 including its claim in Antarctica).
What country has only 1 time zone?
China
Though China is almost as wide as the continental United States, the whole country is officially in just one time zone — Beijing time.
Why can’t Russia have one time zone?
Russia has 11 time zones across its vast territory — and its leaders believe that’s just too many hours in the day. Russia has 11 time zones across its vast territory — and its leaders believe that’s just too many hours in the day.
What makes US and Russia have 11 time zones?
The country was divided into eleven time zones in 1919, after the Bolshevik Revolution, with boundaries going along railroads and rivers, although these time zones have since been revised multiple times.
Do other countries have time zones like the US?
There are 23 countries with at least two time zones. Since all lines of longitude coverage at the North and South Poles, Antarctica and the Arctic technically have all time zones.
Who decided the time zones?
Sir Sanford Fleming
Sir Sanford Fleming, a Canadian engineer, was the first person to propose the use of worldwide time zones back in 1878. His idea was to divide the world into 24 time zones that were each 15 degrees of longitude apart. The reason for this is that the earth rotates 15 degrees every hour, or 360 degrees in 24 hours.
Who decides time zones?
The U.S. Department of Transportation (DOT)
Overview. The U.S. Department of Transportation (DOT) oversees the Nation’s time zones. The oversight of time zones was assigned to DOT because time standards are important for many modes of transportation. DOT regulations at 49 CFR part 71 contain the official listing of the Nation’s time zones.
Does USA have 7 time zones?
There are six designated US time zones; and there are four time zones in the contiguous USA. The Aleutian Islands, a spur of Alaska, and the Hawaiian Islands in the Pacific Ocean are 3750 km (2330 mi) apart but lie at similar longitudes.
Why does France have 12 time zones?
1. France has more time zones than any other country, at 12 worldwide. 2. This is due to France’s far-flung overseas areas, since the mainland European part of France uses just one time zone.
Which country has 5 time zones?
From the options Canada has 5 time zones, Russia has maximum number of times zones 11, USA has 6 times zones and India has only 1 time zone.
Can a country have multiple time zones?
Russia: The only country in the world that has all its time zones over the mainland is Russia. Once the biggest country in the world, Russia has 11 time zones.
Who divided the country into 4 time zones?
In 1878, Canadian Sir Sandford Fleming proposed the system of worldwide time zones that we use today. He recommended that the world be divided into twenty-four time zones, each spaced 15 degrees of longitude apart.
What is the purpose of time zones?
A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.
