“Saved time” most commonly refers to Daylight Saving Time (DST)—the practice of advancing clocks during warmer months to extend evening daylight. 1. Daylight Saving Time (DST) Overview
How it works: Often remembered by the phrase “spring forward, fall back,” DST requires pushing clocks ahead by one hour in the spring and setting them back one hour in the fall.
Current Observance Dates (United States): DST begins on the second Sunday in March (clocks go forward at 2:00 a.m. local time) and ends on the first Sunday in November (clocks go back at 2:00 a.m.).
Exceptions: Not all places observe this practice. For example, Hawaii, most of Arizona, and several U.S. territories stay on Standard Time year-round.
Global Use: It is widely used across North America and Europe, though the exact start and end dates vary depending on the country or hemisphere. 2. Origins and Purpose Daylight Saving Time
