The notion of time zone it is used to name the different sections in which the land by twenty four meridians that are separated from each other by an identical distance. In each of these regions, a same schedule .

On the earth's surface, therefore, it is possible to recognize twenty-four areas created from meridians (imaginary lines). The definition of each current time zone is made in relation to the call coordinated universal time or UTC , which is a standard of time established from Greenwich Meridian .

Countries crossed by the Greenwich meridian and those closest to it are governed by the UTC time zone 00:00 . As the planet it turns from west to east, when passing from one time zone to another to the east, it must be add one hour . However, when moving from one time zone to another located to the west, you have to subtract one hour . He 180 ° meridian , meanwhile, set the day change.

That's why if we find ourselves in Paris , the French capital, and we traveled to Cape Verde , we must delay the clock one hour. This is because France is in the UTC time zone 00:00 , while Cape Verde it's in the UTC time zone -01: 00 . Yes since France Instead, we turn to Congo , we will have to advance one hour (when passing the UTC time zone +01: 00 ). It is important to keep in mind that spindles can be modified according to the time of year.

In other cases the difference between the time zones is much greater. When in Argentina Are the 14 hours , by example , in New Zealand Are the 5 hours the next day The explanation is that the time zone of Argentina is UTC -03: 00 and that of New Zealand , UTC +12: 00 . There are, then, 15 hours apart between one territory and the other.

Understand the conversion from one time zone to another it is not very complicated, but for most people this formula has no use, since the schedules of events within the same region always correspond to the local time zone, which all citizens use to adjust their watches. As if this were not enough, currently all devices are capable of changing the time in spring and autumn to meet the conditions of the so-called summer schedule , so almost nobody has to worry about doing it manually.

With respect to summer schedule, which is also known by the name of saving time of light, it is a strategy used internationally to save electricity. It consists of advancing one hour when spring begins and delaying one in autumn, so that citizens can take more advantage of sunlight and need to consume less electricity without affecting their daily obligations.

Since summer time is a convention that is not respected by all countries of the world, but only a few, international communications are affected with each adjustment . For example: until the previous day of the change in which one hour is advanced, between two given countries there may be five hours of difference, while the next day the number amounts to four. If either party does not remember this detail, you may be late for a meeting or even miss an important interview.

As mentioned above, people who do not relate to people from other countries or who do not watch live broadcasts coming from abroad do not usually pay attention to time zones, while for the rest it may be one of the fundamental aspects of their organization .
