When is Daylight Saving Time?

Answer 1

In 2019, daylight saving time in the United States began on March 10 at 2 a.m. local time, and it will end on Nov. 3 at 2 a.m. local time. In the spring, clocks are set forward by one hour, and in the fall, they are set back to their original time.

Daylight saving time (often referred to as "daylight savings time") starts and ends on different dates every year, as they always fall on Sundays. These dates also vary by country and region.

The practice of turning clocks forward an hour throughout the summer months was established in the early 20th century as a means of reducing the amount of fuel required for electric power. Today, there is much debate over the efficacy of daylight saving time, with multiple studies in disagreement over its reduction of energy usage, economic benefits, and health concerns. In one survey, two-thirds of respondents didn’t see the point of it. Still, over 70 countries observe the clock-changing ritual.

Answer 2

United States and Canada:

In 2018, Daylight Saving Time (DST) begins March 11.

Set your clock(s) forward one hour at 2:00 AM on the second Sunday in March.

It ends on November 4, when the clocks will need to go back an hour.

Daylight Saving Time dates change from year to year. It begins on the second Sunday of March, and ends on the first Sunday of November. The clock moves forward one hour in March, and back one hour in November.

Future years:

2019: DST begins March 10 and ends November 3

2020: DST begins March 8 and ends November 1

2021: DST begins March 14 and ends November 7

2022: DST begins March 13 and ends November 6

2023: DST begins March 12 and ends November 5

2024: DST begins March 10 and ends November 3

2025: DST begins March 9 and ends November 2
