A time zone is an area which 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. Time zones are defined as one or two offsets from Coordinated Universal Time UTC , and if two offsets are used the days when the offset changes. Some time zones switch between offsets throughout the year due to daylight saving time DST. Areas of extreme latitude are more likely to use DST. DST is usually used for about half of the year, typically by adding one hour to local time during spring and summer.

Weather observations around the world including surface, radar, and other observations are always taken with respect to a standard time. It is also known as "Z time" or "Zulu Time". To obtain your local time here in the United States, you need to subtract a certain number of hours from UTC depending on how many time zones you are away from Greenwich England. The table below shows the standard difference from UTC time to local time. The switch to daylight saving time does not affect UTC. It refers to time on the zero or Greenwich meridian, which is not adjusted to reflect changes either to or from Daylight Saving Time. However, you need to know what happens during daylight saving time in the United States. In short, the local time is advanced one hour during daylight saving time. As an example, the Eastern Time zone difference from UTC is -4 hours during daylight saving time rather than -5 hours as it is during standard time. Disclaimer Information Quality Help Glossary.

Therefore, establishing a global timezone system seemed like a rational step for everybody.

A time zone is a region on Earth that observes the same time. This way, it will be the same hour in all the countries and the cities in the particular time zone they observe. Time zones run horizontally rather than vertically: Moscow and Paris will have different time zones, but Cape Town and Madrid observe the same time. As you can imagine, noon is at different times in each country, which means that noon 12 PM would be observed at different times from country to country corresponding to their position West or East. Without a standard time that all countries in a time zone must observe, the countries would never observe at the same time. Time zones are very important for commercial and social activities, legal reasons, military use, trade, and just about every other human activity on the planet.

The practice has spurned plenty of debate over the years, as many feel it adds unnecessary disruption to our circadian rhythms. Most recently, the Sunshine Protection Act aimed to make daylight saving time permanent beginning in spring , but was stalled in the House, despite unanimously passing through the Senate. And in the absence of nationwide movement, states are taking the matter into their own hands—at least 29 states considered legislation related to daylight saving time in In the spring, daylight savings begins, moving an hour of sunlight from the morning to the evenings, allowing people to take advantage of the natural light during the supposedly warmer months. In the spring , clocks will move forward by an hour at 2 a. In the fall, clocks jump back an hour at 2 a.
