Time is a fascinating concept that has puzzled humans since the dawn of civilization. Keeping track of time becomes more complicated when we consider daylight savings time and standard time. But what exactly are these and which one are we currently on? Let’s find out.
Understanding Time Zones
A time zone is a region of the Earth where the same standard time is used. Time zones exist to make our lives easier by ensuring each place on the planet has a consistent time, making it easier to schedule events, travel, and communicate with people globally.
There are 24 standard time zones in the world, each 15 degrees of longitude wide. The full width of the Earth is 360 degrees, so each time zone is nominally 1 hour ahead or behind its neighbors. In reality, the boundaries of most time zones are not straight, meaning they can vary in size and shape.
Standard time is also known as winter time, as it is the time that a region observes during the coldest months of the year. It is determined using the sun’s position relative to the earth and is calculated based on the mean solar time at the time zone’s central meridian. This means that the time is calculated using the time that the sun is highest in the sky.
What is Daylight Savings Time (DST)?
Daylight Savings Time (DST) is a practice where the clock is moved forward by one hour in the summer to extend the amount of daylight available in the evenings. DST allows us to enjoy more sunlight in the evenings, saving energy and time. It was first proposed by Benjamin Franklin in 1784, but only became popular during World War I when several countries adopted the practice to conserve energy.
DST starts in the spring and lasts until the fall. The time shift happens overnight on a Sunday, generally the second Sunday in March, at 2 a.m. The clock jumps ahead by one hour, meaning that 2 a.m. becomes 3 a.m. This means we lose an hour of sleep, but we gain an hour of daylight in the evenings. DST ends in the fall, when we turn the clocks back one hour, typically on the first Sunday in November at 2 a.m.
The Pros and Cons of DST
Like most things in life, DST has its benefits and drawbacks. Here are some of them:
- More daylight in the evenings: This allows us to enjoy more time outside, reduces electricity consumption, and promotes outdoor activities like exercise and socializing.
- Reduced crime: Studies have shown that crime rates decrease during DST, as there is more light in the evenings and people are less likely to be out and about in the dark.
- Saving energy: By making better use of natural light, we can reduce our reliance on artificial lighting and save energy.
- Disrupts sleep patterns: The time shift can disrupt our circadian rhythm, making it harder to fall asleep and wake up.
- Increased risk of accidents: The time shift can affect our mental and physical abilities, making it harder to perform tasks safely and effectively.
- Not suitable for all regions: Some regions, like the tropics or polar regions, do not benefit from DST as they already experience long periods of daylight or darkness throughout the year.
Are We in Standard Time or Daylight Savings Time?
As of November 2021, we are currently in standard time. DST ended on November 7th, 2021, meaning that we turned our clocks back one hour at 2 a.m. that day. We will remain in standard time until March 2022, when DST will begin again.
How to Check Your Time Zone
Checking your time zone is easy. The easiest way to find out your time zone is to check your phone or device settings. Most devices automatically adjust for time zones, but it’s always a good idea to check that they have the correct time zone set.
If you’re traveling and need to check the time zone for a different location, you can use a time zone converter tool. There are many free ones available online that allow you to enter a location and find out the current time in that area.
The History of Daylight Savings Time
Daylight savings time is a practice that has been around for more than 100 years. It was first proposed by Benjamin Franklin in 1784, although it was not widely adopted at that time. The idea was reintroduced in the 1890s by a British builder named William Willett.
Willett was an avid golfer who hated the fact that he had to stop playing golf in the evening due to the lack of daylight. He proposed a plan to advance the clock by 20 minutes each Sunday in April and reverse it in the same way in September. However, his idea was not taken seriously by the government until after his death.
During World War I, many countries began to adopt DST as a means of conserving energy. Germany led the way, with the United States following shortly after. DST was widely adopted during World War II but was later abandoned after the war ended.
DST was reintroduced in the United States in 1966 under the Uniform Time Act, which standardized the beginning and end dates of DST across the country. Since then, there have been several modifications to the dates and times that DST starts and ends, causing confusion and controversy for some.
Time is a fascinating concept that has evolved and changed over the course of human history. DST and standard time are just two examples of this evolution, and they have caused their fair share of confusion and controversy.
As we approach the end of DST and transition back to standard time, it’s important to remember to check your clocks and devices to ensure they have the correct time zone set. This small step can help ensure that you’re on time for meetings, appointments, and other important events.

Common Questions and Answers
- Q: What is the purpose of daylight savings time?
- Q: Does daylight savings time apply to all states in the United States?
- Q: When does daylight savings time begin and end?
- Q: Is daylight savings time necessary?
A: DST provides more daylight in the evenings, reducing energy consumption, increasing opportunities for outdoor activities, and promoting tourism.
A: No, some states like Hawaii and most of Arizona do not observe DST.
A: DST typically starts on the second Sunday in March and ends on the first Sunday in November, though the dates and times can vary depending on the country or region.
A: Opinions on the necessity and efficacy of daylight savings time vary. Some argue that it provides significant benefits in terms of energy, safety, and productivity, while others argue that it causes unnecessary sleep disruption and confusion.
