Due to the fact that the size of our planet is huge, at the same time interval, in different parts of the Earth - its own local solar time. And in order to avoid confusion in clarifying the question: “So what time is it?”, A standard time system was adopted. And the Earth was conditionally divided into 24 time zones. The reference point is the meridian zero, from which the time zones +1, +2, +3, etc. go to the east, and -1, -2, -3, etc. to the west. So, thanks to the system of time zones, now it’s quite simple to determine the desired one.
You will need
- - a computer
- - map of time zones
- - world map showing degrees of longitude
Instruction manual
1
Turn on the computer and click on the clock indicator in the lower right corner of the screen. Now, in the window that opens, click on the "Change date and time settings" function. And, already in a new window, select the "Change time zone" function. You will see a long list of time zones with a list of cities that relate to them. Of course, only the capitals of states are indicated here and there are no small towns. So, if you want to know the time zone of a small city - just find the capital of his country in this list, because, usually, within one country there is one time zone.

Use an ordinary world map on which the average meridians are indicated in detail: 0 °, 15 °, 30 °, 45 °, 60 °, etc. The fact is that one time zone occupies approximately 15 °, but not clearly from 0 ° to 15 °, from 15 ° to 30 °, from 30 ° to 45 °, etc., but with an offset of 7 ° 30. So, in order to determine the boundaries, for example, of the UTC + 1 time zone, it is necessary to draw lines to the right and left of the middle meridian of 15 ° east longitude at a distance of 7 ° 30 '. In order to determine the time zone of a place, which is located, for example, in the region of 60 ° west longitude, we must calculate its position with respect to the zero meridian: 15 ° - one, 30 ° - two, 45 ° - three, 60 ° - four. This means 60 ° west longitude - the time zone is UTC-1.

Use the detailed timezone map. Such a map is the simplest and most reliable way to determine the time zone of a particular point on the globe. Since here, not only the boundaries of each of the 24 time zones are indicated, but there is also a note - does the country switch to summer time. It looks, for example, like this: +1 (+2), and means that the country belongs to the UTC + 1 time zone, but in the summer, it refers to the UTC + 2 time zone. Of course, do not forget to consider that in different hemispheres, summer and winter are at different times. Another big plus of such a card is the ability to determine whether different time zones operate on its territory, as in Russia, or, despite the large territory, only one zone is accepted, as in China.
note
Despite the generally accepted system of time zones, in reality, in order to maintain a uniform time within one country or administrative unit, the borders of the zones are shifted, so some time zones are replaced by neighboring ones in places.
Useful advice
When determining the time zone, do not forget that in some countries the local time differs from the universal time not only by a standard hour, but also by an additional 30 or 45 minutes.
