Why are the lines on a time zone map not straight?
To expand a bit, they are not straight for one primary reason: logistics. If the timezones were perfectly straight, then each hour time change would occur in 15 degree increments on either side of 0 longitude (Greenwich). That’s bad news for a city like Denver which straddles longitude 105 W.
Why are some states split between time zones?
Time zones are crooked because it is up to each government to regulate them in their country. There are standard time zones for the world, but where exactly those lie and whether to split the country up according to these is a decision made by individual nations.
Why do time zone boundaries not always line up perfectly with lines of longitude?
Why do time zone boundaries not always line up perfectly with lines of longitude? To avoid any confusion time zones go around towns, cities, and areas of a country. Why does a Mercator projection exagerate the areas of landmasses near poles?
What is the time of America called?

Why does Arizona have two time zones?
Arizona used DST, along with the rest of the US, during World War I in an effort to conserve fuel for the war. Also known as War Time, DST was used in Arizona from March 31 to October 27, 1918. At that time Arizona had 2 time zones.

Why doesn’t Arizona observe Daylight Savings Time?
Arizona exempted itself from observing DST in 1968, according to the Congressional Research Service. Timeanddate notes that DST is “largely unncessary” due to Arizona’s hot climate and that the argument against extending the daylight hours is that people prefer to do their activities in cooler evening temperatures.
Why are time zone lines not always straight?
Time zone lines are not always straight in order to accommodate the desires of nations within the boundaries of the zone. The irregularity is mainly due to political factors and has nothing to do with geography or any other natural cause.
What is the width of the time zone lines?
Time zone lines, when not deflected for political reasons, are 15 degrees of latitude in width. The boundaries are arranged over both land and sea. Each line is one hour earlier than the last line to the east, but within the boundaries of the time zone itself, time is not set earlier in the west than in…
Why is time set earlier in the west than in the east?
Each line is one hour earlier than the last line to the east, but within the boundaries of the time zone itself, time is not set earlier in the west than in the east. Many countries in South America deflect time zone lines around their boundaries so that the entire nation is within the same time zone.
