Why do some countries have more than one time zone?
Time zones are set up so that the sun will be close to directly overhead at noon in the center of each of them, and each one is one hour apart from its neighbors. Some countries are so wide that they need more than one. The boundaries really ought to be straight lines, but they get jiggered around for political or convenience reasons.
Which time zones are occupied by the fewest countries?

How many minutes apart are time zones?
However, the International Date Line (IDL) creates 3 more. Also, several time zones are only 30 or 45 minutes apart, increasing the total number of standard time zones even further.
How wide is the time zone?
Theoretically, each 1-hour time zone is 15 degrees wide, indicating a 1-hour difference in mean solar time. This can be seen as the white and gray stripes on our Time Zone Map and in the image above.
What is the time zone for daylight savings time?
During Daylight Saving Time (DST) the time zone name and time changes. The words “daylight” or “summer” are then usually included in the name, and the local time is usually set forward 1 hour. For example, California uses Pacific Daylight Time (PDT) during the DST period with a UTC offset of UTC-7, but Pacific Standard Time (PST) ...
Where is UTC measured?
Defined by UTC Offset. Every place on Earth is measured in terms of its distance east or west of the prime meridian (0° longitude) in Greenwich, London, United Kingdom. This is also the reference point for Coordinated Universal Time (UTC) with 1 hour per 15 degrees longitude.
How many hours ahead of UTC is 75 degrees?
At 75 degrees east (or 75° E) longitude, the time would be 75 degrees divided by 15 degrees = 5 hours ahead of UTC, or UTC+5. Below are all the different local times currently in use worldwide.
How to find the time zone of a longitude?
You have to divide the longitude, in degrees, by 15 to find the appropriate time zone, in hours. For example: At 150 degrees west (or 150° W) longitude, the time should be 150 degrees divided by 15 degrees = 10 hours behind UTC, or UTC-10. At 75 degrees east (or 75° E) longitude, the time would be 75 degrees divided by 15 degrees = 5 hours ahead ...
Is Arizona in the same time zone as California?
For instance, during DST, it is common to say “California and Arizona are now in the same time zone.” However, the correct thing to say would be: “California and Arizona now have the same local time.”

Washington. In Canada, the following provinces and territories use PST in the winter and PDT in the summer: British Columbia - except for some eastern ...
What is the Pacific Standard Time?
The Pacific Standard Time (PST) or sometimes called PT, is consistent with UTC -8. As most people know, the time zones' differences to each other are relevant to the Universal Time Coordinate (UTC). UTC refers to the time in the prime meridian, which lies in zero longitudes.
What is the UTC in the military?
This time zone is a military time zone often used in aviation and the military as another name for UTC -8. U is commonly used at sea between longitudes 127.5° West and 112.5° West. The letter U is used as a suffix to denote a time being in the Uniform Time Zone.
How long is Pitcairn in time?
Pitcairn Standard Time is eight hours behind UTC. It is used during standard time in the Pacific. U - Uniform Time Zone (Military Time) Uniform Time Zone is eight hours behind the Coordinated Universal Time. This time zone is a military time zone often used in aviation and the military as another name for UTC -8.
What are the abbreviations for time zones?
Abbreviations. Main article: List of time zone abbreviations. Time zones are often represented by alphabetic abbreviations such as "EST", "WST", and "CST", but these are not part of the international time and date standard ISO 8601.
How many time zones are there in Russia?

What is daylight saving time?
Many countries, and sometimes just certain regions of countries, adopt daylight saving time (DST), also known as summer time, during part of the year. This typically involves advancing clocks by an hour near the start of spring and adjusting back in autumn ("spring forward", "fall back"). Modern DST was first proposed in 1907 and was in widespread use in 1916 as a wartime measure aimed at conserving coal. Despite controversy, many countries have used it off and on since then; details vary by location and change occasionally. Countries around the equator usually do not observe daylight saving time, since the seasonal difference in sunlight there is minimal.
What is the nautical time zone?
As an ideal form of the terrestrial time zone system, nautical time zones consist of gores of 15° offset from GMT by a whole number of hours. A nautical date line follows the 180th meridian, bisecting one 15° gore into two 7.5° gores that differ from GMT by ±12 hours.
What is 14:45:15 UTC?
Likewise, "14:45:15 UTC" is written as "14:45:15Z" or "144515Z". UTC time is also known as "Zulu" time, since "Zulu" is a phonetic alphabet code word for the letter "Z". Offsets from UTC are written in the format ±hh:mm, ±hhmm, or ±hh (either hours ahead or behind UTC).
What is the Greenwich Mean Time?
The Royal Observatory, Greenwich, founded in 1675, established Greenwich Mean Time (GMT), the mean solar time at that location, as an aid to mariners to determine longitude at sea, providing a standard reference time while each location in England kept a different time.
How long is the Sun in the sky?
This variation corresponds to four minutes of time for every degree of longitude, so for example when it is solar noon in London, it is about 10 minutes before solar noon in Bristol, which is about 2.5 degrees to the west.
