The agreement established an official time as well. An agreement between the major companies was put forth in 1883.
The railroad had exploded across the American landscape by this time, and the train companies wanted their trains to run on time. You already know that Pacific is three hours behind Eastern.Īmerican railroad companies helped by using the time zones for their train schedules. Mountain is one hour behind Central and two hours behind Eastern. Each time zone as you go west is one more hour behind. It divided the United States into four time zones: Eastern, Central, Mountain, and Pacific. This arrangement was adopted by many countries. It wasn’t until 1878 that man named Sanford Fleming (who was born in Scotland but moved to Canada) proposed dividing the world into 24 time zones, each spaced a certain distance apart, according to measurements made on a globe. But nobody really had an idea yet that time zones were needed. Sundials, water clocks, and other time pieces marked the passage of the Sun across the sky, but nobody was talking about seconds, minutes, or hours way back then.Ī few hundred years ago, clocks and watches were invented and timekeeping became a focus for many people. For thousands of years, people didn’t even keep track of time at all, at least not in the way that we know. We didn’t always have time zones, though. The same is true of business and other parts of life. and also have sunlight to greet those schoolkids. in New York, California schools can have kids show up for school at 8 a.m. Parts of the earth are pointed toward the Sun for half of the day and then the other parts of the earth are pointed toward the Sun for the other half of the day.

Each day, the earth completes one full turn. Why? Because the earth turns, that’s why. in New York, kids who go to school in California would have to go to school in the dark if they had to go at the same time as you do. It’s the law because most countries want to have a standard number of hours for daylight, no matter where in the country you live. It’s the law in the United States and in most countries in the world.
