Introduction

Daylight Saving Time (DST) has been a topic of debate for years. Some people love the extra daylight in the evening, while others find the changing of clocks disruptive. Understanding when DST starts and ends can help you prepare for the transition. This article breaks down the specifics of DST, its history, and its impact.

What & Why

What is Daylight Saving Time?

Daylight Saving Time is the practice of setting the clocks forward one hour from standard time during the spring and summer months and back again in the fall. This essentially shifts an hour of daylight from the morning to the evening.

Why Do We Observe Daylight Saving Time?

The primary reason for DST is to better align our waking hours with sunlight. By moving the clock forward, people can enjoy an extra hour of daylight during their evenings. Proponents argue this reduces energy consumption, promotes outdoor activities, and boosts retail sales. — 116 Evergreen Ct, Saylorsburg PA: Home & Property Details
