South Carolina is located in the Eastern Time Zone of the United States. UU. It is 5 hours behind Greenwich Mean Time and 4 hours in daylight saving time. There are 37 time zones in the world and six of them (or seven during daylight saving time) cover the 50 states that make up the United States.
Within those time zones, 13 states are divided into two zones. Very often, only a small portion of these states are in a different time zone than the rest of the state. However, South Dakota, Kentucky and Tennessee have been reduced by almost half due to the time zone change. This isn't unusual, since time zones around the world move in a zigzag pattern along lines of length without a defined pattern.
But why are time zones like that and how exactly is the United States divided? Time zones are crooked because it is up to each government to regulate them in their country. There are standard time zones for everyone, but deciding where exactly those zones are located and whether to divide the country according to them is a decision made by individual nations. The United States Congress, for example, standardized its time zones. When drawing the boundaries for the first time, officials tried to avoid dividing metropolitan areas and took into account other factors that could have complicated the lives of residents in each area.
In reality, time lines follow state lines, but that's certainly not always the case, as you'll see in the next 13 states. Most western states are in the Pacific time zone. Idaho and Oregon are the two states with small portions after mountain time. From Arizona and New Mexico to Montana, the southwestern and Rocky Mountain states mostly use mountain time.
Arizona (apart from the Navajo Nation) does not observe daylight saving time and therefore shares the time, as an MST state, with the Pacific states during daylight saving time. However, this time zone peaks at the borders of some states, leaving five states with a time divide between Central Mountain. Across the center of the United States is another time zone line that divides five states between the central and eastern time zones. Alaska is the largest state in the country, so it's logical that it's in two time zones.
But did you know that Alaska has its own time zone? This, called the Alaska time zone, covers almost every part of the state. The exceptions in Alaska are the Aleutian Islands and St. Lawrence Island, which are in the Hawaiia-Aleutian time zone.
