Why are there different time zones and which countries on Earth have the same time of the day?
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.
What is the point of time zones?
A time zone is an area that 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.
Why do countries change their clocks?
The clocks changing is all part of Daylight Saving Time – which began over 100 years ago as a way to make sure people had more sunlight during summer working hours, as well as a way to conserve energy during the First World War.
Why do some countries have many time zones Class 9?
Large countries have many time zones because they have a large width and a vast East to West extent.
Who decided time zones?
Sir Sandford Fleming
In 1878, Sir Sandford Fleming (1827? 1915) developed the system of worldwide time zones that we still use today. He proposed that the world be divided into 24 time zones, each spaced 15 (fifteen degrees) of longitude apart (like 24 sections of an orange).
How many countries have different time zones?

What would happen if we stopped daylight Savings?
We would experience those later sunsets in the summer, but you would most notice the change during the winter months. On the shortest day of the year, December 21, the sun wouldn’t rise until 8:54 a.m. That’s almost a 9 a.m. sunrise. And the sun would set at 5:20 p.m.
Why is it necessary for some countries to have more than one time zone class 6?
Some of the countries are so big, i.e. they cover a land area, so large, that more than one set of 15 degrees of longitudes intersect the country, thus resulting in two or three or more time zones in that country. This is why some countries have more than one time zones.
Why do some countries have more than one time zone name to such countries?
Time zones are based on the fact that it takes one hour for the earth to rotate 15 degrees on its axis. That means that large countries that span more than 30 degrees of longitude usually have different time zones.
Which country has the most time zones?
Russia is the country to have most consecutive number of time zones. Russian time zones are UTC-2, UTC-3, UTC-4, UTC-5, UTC-6, UTC-7, UTC-8, UTC-9, UTC-10, UTC-11 and UTC-12.
Why do countries change their time zones?
The Earth’s rotation is the primary cause why countries follow different time zones. Without it, noontime will be morning or even evening in other places. Many time zones were created before, confusing travelers about the time. In the 1800s, scientists used a new system for time zones based on the degrees of rotation and longitude.
What countries are in GMT?
Burkina Faso
Does the USA have different time zones?
UTC-12: Anywhere on Earth ( AoE)
Why do the time zones not have straight boundaries?
Time zone lines are not always straight in order to accommodate the desires of nations within the boundaries of the zone. The irregularity is mainly due to political factors and has nothing to do with geography or any other natural cause.
