Understanding the time standard and time zones is useful if you work, communicate, or collaborate with people who live in different countries than you. Knowing how time zones work and how to calculate time in different locations around the planet helps you plan and communicate better — after all, no one wants to get a work call or a Zoom invitation for midnight or two in the morning, even though it may be a perfectly reasonable time on your end! Next up, we will provide a list of the major territories that are located in the CDT time zone, as well as all the major cities in this region. Because the Earth is a sphere that rotates, it cannot be noon at the same time all over the world: as the Earth turns, the sun hits different regions at different times. To keep track of time around the world accurately, scientists split the planet into 24 slices, each slice accounting for 15 degrees of longitude counting from the Greenwich Meridian, also known as longitude zero. Each slice is a time zone that is 15, 30, 45, and so on degrees West or East from Greenwich; one slice accounts for one hour behind or ahead the Greenwich Mean Time GMT , which sits atop the zero longitude. Now, time zones are calculated by degrees West or East rather than North or South. This is because, once again, the Earth rotates around its axis, but the poles do not move. However, if the countries are located West or East of each other, they will observe a different time — this is why Spain and Russia, as an example, are in different time zones despite being much closer than Spain is to South Africa.
