A term “time zone” describes an area where uniform standard time isused for the legal, social or economical purpose. The time zones are not strict: they follow the boundaries of countries, because it would be inconvenient otherways. The offset from world’s standard time (Coordinated Universal Time UTC) expressed as UTC- or UTC+ defines ...
Please note that the Time Zone Map is not a political map but a time zone map showing the time zone boundaries. How to Use the Map. Search for any city in the search field above and place a black "pin" by that city on the map. If you place more than one pin, an extra line of information is added underneath the map with links to those cities' pages.
The change from Daylight Saving Time to Winter Time (Standard Time) is done in each country according to individually defined rules. Within the USA, it is always the second Sunday in March and the first Sunday in November. The time is always 2:00 A.M. in the respective time zone. This is different in the European Union.

Most large countries that span a range of longitudes (e.g., USA,Canada, Russia ) have multiple time zones. This ensures that civil time isn’t too far from the local solar time.The apparent solar time is the time measured by the position of the sun, where noon is the instant when the Sun crosses the local meridian and reaches its highest point in th...
Greenwich Mean Time (GMT) is the solar time at Greenwich at 0° longitude. Civil time doesn’t always match the exact GMT. Coordinated Universal Time (UTC)is used to substitute GMT with the more precise and rigorous determination of time. The main feature that differs UTC from GMT is the way of keeping track of time based on a 24-hour system that sta...
How many time zones are there in the world?
The acceptance and application of the idea of time zones took almost a century. Initially, the world was divided into 24 standard time zones which extend from the South Pole to the North Pole. However, due to different geographical, social, and political reasons, the time zones may deviate from the universal standards and recommendations set by international institutions. Governments often set time differently. They try to reflect not only the positions of the sun regarding the surface but in...

How many zones are there in the United States
The modern United States is known to have nine time zones. The legal system defines them and reflects nine different parts of the United States. Subject to the law, there are Eastern, Atlantic, Mountain, Central, Pacific, Alaska, Hawaii-Aleutian, Samoa, and Chamorro zones5. They span all over the country and refer to offsets ranging from UTC-11 to UTC-4 and correspond to the vast size of the United States. However, one should understand that some of them are only applicable to certain small t...
One of the explanations for the skewing time zones is that the countries cross the time zones. For example, the border between India and Nepal provides a 15 minutes difference, as India has UTC+5.5, while Nepal, being located a bit further to the East, follows UTC+5.75. The explanation is simple as the countries span across the +5/+6 line. Burma, A...
It is a serious task to regulate and provide countries with proper timekeeping all around the world. That’s why a lot of organizations have appeared to be in charge of this duty. For example, the United States of America is provided with services of timekeeping by two federal agencies: The National Institute of Standards and Technology (NIST) and t...
Even though the system of dividing the surface of our planet into 24 sectors-meridians is very clear, in reality, the implantation of this system has suffered some changes and adjustments in some countries. Although China is quite a big country with a large population and on top of that, geographically it occupies 4 time zones. But after the revolu...
The framework of Daylight Saving Time (DST) was proposed by Benjamin Franklin, when being in Paris, and is concerned with advancing the standard time within the region or zone by one hour to enhance the amount of daylight time9. In 1784, Benjamin Franklin underlined that the Parisians sleepover the majority of daylight hours, while George Hudson an...
The history of Greenwich Mean Time takes us back to the discovery by Christopher Columbus and the geography treaties that eventually gave birth to the measurements of the Earth in terms of longitudes and latitudes. As soon as astronomers began measuring time according to the position of the stars, it became evident that the time can’t be the same e...
Today, this system is use for the time zones around the world with positive and negative offsets from UTC. This offsets range from UTC-12:00 in west to UTC+14:00 in the east. It is important to remark that Daylight saving time doesn’t change the UTC time. It is the local time that may change with summer time, but not the UTC time.

Daylight Saving Time (DST) is the practice of setting the clocks forward one hour from standard time during the summer months, and back again in the fall, in order to make better use of natural daylight. Clocks are set forward 1 hour for DST in the spring. The sculpture is of "Six Public Clocks" in Canary Wharf, London, U.K.
