What Is Daylight Saving Time?

Daylight Saving Time (DST) is an annual clock-changing method to give the extended length of the day increased use of 1 hour of sunlight from natural daylight that falls on each day at sunrise, thus providing more opportunities for efficient use of light.

The time change systematically occurs every year as Clocks are turned ahead 1 hour in the spring and turned back 1 on the fall.

The primary purpose of the 1-hour time change is to allow people to spend the extra hour in sunlight both after normal work hours, and therefore, increasing the amount of after-work and longer daylight hours to allow for more recreational use of daytime. 

This has been a benefit to the many people who enjoy their next activity after work or business & aids them in maximizing their outdoor activities in the areas of their normal work days as well as providing increased levels of business activities during the increased hours that are typically available in their working days. 

The Real Reason Clocks Shift Twice a Year

There are various reasons for adjusting clocks twice a year with Daylight Saving Time. Some of the main reasons include:

• More use of daylight hours: Changing the clock gives people the opportunity to have additional daylight in the evening during the long summer days.

• Electricity savings: This program was originally created to save electricity by reducing the amount of artificial light that people needed at night.

• Increased commerce: Longer daylight hours in the evening can encourage people to shop, eat at restaurants, and participate in outside activities.

• Increased safety on roadways: With more light during the evenings, there will be fewer car accidents and better visibility for those commuting home from work.

• More efficient daily routines: Adjusting the clock will make it possible for people to organize their scheduled work hours to be in-sync with sunlight, creating an efficient use of natural light.
