What is a Time Zone?

A time zone is a 15o split of the world’s surface that starts at Greenwich, England. It was made so that people could find out what time it is in other parts of the world.

Today, it’s more of a political divide than a physical one, because sometimes people in not-so-far-away places need to be on the same time. We also have Daylight Savings Time, which is also a change in the time zone, because it saves energy.

Most of the time, your country’s government or an astronomical organization sets the rules for time zones, which are represented by 3 or 4 letters. Check out the samples in Section 3.2.

History of The Standardization of Time Zones

Sir Sandford Fleming, a Canadian, came up with the idea for the time zones we use today in 1878. He thought the world should be split into 24 time zones, with 15 degrees of longitude between each one. Since the earth spins around once every 24 hours and there are 360 degrees of longitude, the earth moves 15 degrees of longitude every hour. People all over the world thought that Sir Fleming’s idea of time zones was a brilliant way to solve a confusing situation.

On November 18, 1883, train companies in the United States began to use Fleming’s standard time zones. In 1884, there was a meeting in Washington, D.C., called the International Prime Meridian Conference. The goal was to set a standard time and choose the prime meridian. The longitude of Greenwich, England, was chosen as zero degrees longitude, and the 24 time zones were set up based on the prime meridian.

Even though the time zones were set, not all countries changed right away. Even though most U.S. states started to use the Pacific, Mountain, Central, and Eastern time zones by 1895, it wasn’t until the Standard Time Act of 1918 that Congress made using these time zones required.

How Do Time Zones Work?

There are four time zones in the mainland United States. These are the Eastern, Central, Mountain, and Pacific time zones. Alaska and Hawaii also have their own time zones.

There is one hour between the Eastern, Central, Mountain, and Pacific time zones. Since the sun always rises in the east, the time in the Eastern time zone is always the newest. So, 8 a.m. in the Eastern time zone is 7 a.m. in the Central time zone, 6 a.m. in the Mountain time zone, and 5 a.m. in the Pacific time zone. It would be 4 a.m. in Alaska and 3 a.m. in Hawaii.

Here is another example:

If you live in the Eastern time zone but the big game starts at 5 p.m. in the Central time zone, just add an hour and turn on your TV at 6 p.m. EST. If you live in the Pacific time zone, take two hours off and start watching at 3 p.m. PST.

Chicago’s Daylight Savings Time (DST)

Time changes because of Daylight Saving Time (DST). We wake up an hour earlier in the summer because of this. Without DST, the sun would rise in Chicago at 4:15 a.m. on June 19 and set at 7:29 p.m. on the same day. With DST, the sun will rise at a more acceptable time of 5:15 a.m., and set at 8:29 p.m., and kids will be able to play outside late into the night.

Benjamin Franklin is often given credit for coming up with the idea of Daylight Saving Time. Germany began DST in 1916 to save energy during World War I. Its enemies and friends in Europe soon caught up with it.

The United States started using Daylight Saving Time for the first time in 1918. This was the same year that the country officially switched to Standard Time, which I wrote about in my last post. In stark contrast to how quickly people chose to switch to Standard Time in 1883, the switch to DST was very slow and not at all standard. In rural places, people fought back especially hard.
