When is cdt time change

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. This may sound confusing at first, but keeping time this way offers a lot of benefits to people, companies, and even the military around the globe.

As long as you know which time zone you are in and the UTC offset of another country, you can easily calculate the time in that country. Why do some countries around the world switch to Daylight Savings time, while others do not? In essence, moving the clocks forward and back in the spring and fall months is done to extend the daylight hours.

During summer, the sun rises and sets later, which is why moving the time forward by one hour helps extend the daylight giving people more daylight hours and saving energy. However, not all countries around the world use daylight savings. In the Northern and Southern Hemisphere, however, the difference between the length of day in summer and winter is more pronounced, which is why most countries further away from the equator observe Daylight Savings time seasonally.

Ancient Romans seem to have made use of daylight savings, too: history shows Romans used water clocks with different scales to adjust for different solar time throughout a year. The reason is that CDT is not a usual time zone. Instead, as we already mentioned, CDT is used only in certain months and only in the Americas.

This alternative time zone originates in and is exclusively used in North America and some parts of Canada. However, there are still many areas in both countries that refuse to use CDT for stabilizing time during the summer.

Instead, they decided to be a part of the Central Time Zone and chose a permanent daylight saving system, consequently. Moreover, Mexico also refused to adapt to the change. However, in December , the Mexican Congress changed its opinion and let ten cities that are located at the borders switch to the CDT time schedule in according to the US standards. T he first time when North America started using Central Daylight Time was in when the local time changed from local standard time to local daylight time.

Since this time, it usually happens on the second Sunday in March and returns back to the standard time on the first Sunday of November. The only obvious thing is that sometime in the spring we change our clocks so that we will save daylight time in the summer.

But when exactly do people switch their clocks from 2 p. In fact, most of the United States starts switching to central daylight time at 2 a.

They return their clocks back to standard time on the first Sunday in November. This is a military time zone used by aircraft over the sea between the longitudes of We all know the concept of Daylight Saving Time as a practice in the United States where the clocks are moved forward by one hour during the summer and then back to the originally time in the winter.

The result of this time change is more sunlight during the evening hours of the summer. Most of the U. These respective times fall within the months of March and November. The Standard Time Act of was modified by the Uniform Time Act of to require a regulation issued by the Department of Transportation before a state can move from one time zone to another. Under this new legislation, the governor or state representative may submit the required inquiry for the entire state or just a part of it.

After a public hearing, once comments have been made by the people who will be affected by the change, everything is reviewed. Another aspect of the Uniform Time Act dictates that the process of moving an area onto or off of DST in general can only be done through legal action at the state level. States can be exempt from DST but if they observe the practice, they must abide by federal laws. The state of Alaska observes DST and due to the high latitude, it has almost round-the-lock sunlight during summer.

Because of this, many people believe that the practice is a nuisance. Since Phoenix and Tucson are some of the hottest US metropolitan areas, extra sunlight during the summer will skyrocket energy consumption and overall costs. In April of though, eight counties in the west part of the state were shifted into the Central Standard Time zone and it was then that the state started to observe DST and move into the CDT zone during the summer. Currently there are 12 counties observing CDT during the summer and 80 counties observing EDT because of their time zone.

The problem with an idea like this is that it would require the federal government to amend the Uniform Time Act to allow such a scenario. The act specifies specific times of the year to observe DST, causing the issue with this concept.

The only other alternative would be to obtain approval from the DOT to move the state to another time zone. The subject of Daylight Saving Time has been a hot button topic as of late and will only continue to grow as the practice become more and more divisive.

There are arguments to be made on both sides of the equation. For as long as it exists, there will be a Central Daylight Time zone to occupy those states during the summer months when they move their clocks forward into another offset of UTC. Compare Time Difference Between 2 Cities.
