When will the clocks go back in 2024 to end daylight saving time? – Baltimore Sun

With summer coming to an end in a few weeks, the end of Daylight Saving Time is also approaching. The clocks don't have to be changed yet, but in November, Maryland's time will go back an hour.

When is summer time?

In countries that observe daylight saving time, the time change begins on the second Sunday in March and ends on the first Sunday in November of each year.

This year, daylight saving time began on March 10 and ends at 2 a.m. on November 3, so mark your calendar and enjoy an extra hour of sleep. Sunrise and sunset will move forward by about an hour.

On March 9, 2025, time will “jump forward” again.

How did daylight saving time come about?

Some say Benjamin Franklin invented daylight saving time, while others point to other people. According to an article on the website of the Bloomberg School of Public Health at Johns Hopkins University, changing the clocks during the warmer months was introduced as early as World War I to make better use of daylight and thus save energy.

The Uniform Time Act of 1966 introduced a standardized system of daylight saving time throughout the United States.

Who doesn’t observe daylight saving time?

Hawaii and Arizona, with the exception of the Navajo Nation, do not observe daylight saving time. Guam, American Samoa, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands, all U.S. territories, also do not observe daylight saving time, according to the Department of Transportation, which is responsible for time zones.

In 2022, the U.S. Senate passed a bill that would have made daylight saving time the new permanent standard time starting in November 2023, but the bill failed to pass the House of Representatives. In recent years, state legislatures have considered at least 650 bills and resolutions to implement year-round daylight saving time if federal law allows it, according to the National Conference of State Legislatures.

Maryland Rep. Brian Crosby, a Democrat from St. Mary's County, sponsored a bill in 2021 to implement year-round Eastern Daylight Time in the state. The bill did not pass in 2021, nor did subsequent versions re-introduced by Crosby in 2022 and 2023.
