But, as the example of Boston shows, some of us pay a price when it comes to afternoon sunshine. Eastern Daylight Time Time zone in Washington, DC, USA (GMT-4) Reference: Saturday,, 3:36 am There are 344 climate divisions in the CONUS (Continental US). ![]() From west to east, they are Hawaii, Alaska, Pacific, Mountain, Central, and Eastern. observing DST (daylight saving time) for generally the spring, summer, and fall months. The United States is spread across six time zones. The transition went smoothly, and today it’s hard to imagine a world where the time zone could change every few miles. Time in the United States of America, by law, is divided into 9 standard time zones covering the American states, territories and other U.S. Within months, many cities across the country agreed to officially adopt “railroad time.” In 1883, a convention of railway companies adopted the system of time zones we know today. Eastern Time Zone: 5 hours behind Coordinated Universal Time (UTC-05:00). The notion of adopting standard time zones also got a boost from scientists, who wanted to make it easier to compare astronomic observations with colleagues in different cities, and who acted as thought leaders promoting standardized times. This page lists the time zone(s) for each state in the United States. The red lines divide the country in its time zones. The Connecticut experiment was so successful that railroads across the country saw the wisdom in following suit. Below is a time zone map of United States with cities and states and with real live clock. The following year, the entire state agreed to use that same time standard. But, in 1880, Connecticut’s railways began leading the way, adopting New York City time. Note that states may span multiple time zones, so its often better. Given the large number of railroad companies in the country, setting up a system was not a simple matter. South Dakota Texas Alabama Tennessee Oklahoma. In the geographically sprawling U.S., it was clear that there would need to be more than one time zone. To solve the problem, Americans looked to England, where the railroads had established a standard time, set at Greenwich Observatory, to use across the entire country. In the extreme case of Pittsburgh, trains used six different time standards for arrivals and departures. Some train stations had multiple clocks on the walls showing the local times in various nearby cities. The railroads not only brought cities closer together, they also demanded precise timekeeping. People who would once have had to spend weeks traveling from Boston to Washington could now make the trip in less than a day. Between 1830 and the end of the Civil War, the country’s railroad tracks grew from 23 to 35,000 miles. That was a perfectly fine system if you didn’t have to coordinate a conference call with colleagues in another city or tune in to the Super Bowl at the right time-neither of which were an issue before the invention of the radio or telephone.īut another innovation was rapidly connecting cities together. ![]() Tiring of 4 pm sunsets, Boston is considering a move to the Atlantic Time Zone.
