What is A Time Zone & How Does It Work?

The term “Time Zone” is elaborated as the “Region of the earth”. Usually, a time zone shares a similar standard time. Moreover, it represents a 1-hour difference from its nearest zone. The time zones are divided by the longitude lines. For standardizing timekeeping, we use time zones.

How Does A Time Zone Work?

Without a doubt, there is a simple rule to create a time zone. It divides the earth into 24 different longitudinal parts or sections. Each time zone represents the 1-hour difference from the nearest zone. In addition, The Prime Meridian at 0 degrees longitude is the starting point of Greenwich mean time (GMT) which is also known as the UTC “Coordinated universal time”.

Local Time Zone Names

There are different local time zone names that are directly linked to the geographical name of the region. Each time zone can have a different name. But their coordinated universal time offset can be the same. UTC-5 means the instance in Florida or Miami is 5 hours behind. The standard time zone that they use is EST (Eastern Standard Time). On the other hand, in Cuba and Havana, the standard time zone is also UTC-5. But there is a difference. They call their standard time CST (Cuba Standard Time).

What Are Military Time Zones?

Furthermore, there are around 25 military time zones in the world. Also, military time zones follow the rule of 1 hour for 15 degrees. Each military time zone is named according to the NATO phonetic alphabet such as Alpha, Bravo, Charlie, and so on. Moreover, NATO phonetic alphabet or military time zones are used at sea, in aviation, in telecommunication, etc.

Let’s suppose, we apart each time zone by one hour, there would be 24 time zones. On a timezone map, if we draw an actual border with national and international borders, there would be 15-degree longitudes. Furthermore, An IDL (International Date Line) creates 3 different time zones. And each time zone has a difference of 30 to 45 minutes. According to the IDL time zone calculation formula, there are more than 24 time zones in the world.

DST (Daylight Time Zone)

Areas that are using a DTS (Daylight time zone), change their time zone name and time according to the daylight period. Furthermore, the term “Summer” or “Daylight” is also used for the time zone name. On the other hand, the areas that do not use a DTS use a standard time zone for a year. During a DTS period, California uses PDT (Pacific Daylight Time). And the rest of the year, they use PST (Pacific Standard Time).
