New York and most of the United States have shifted to a 5-hour time difference from Coordinated Universal Time due to the commencement of Daylight Saving Time, while Europe will not transition until the end of March.
Starting from midnight today, New York and nearly all of the United States will observe a time difference of only 5 hours instead of the usual 6 due to the beginning of Daylight Saving Time (DST). In the U.S., DST begins on the second Sunday in March and ends on the first Sunday in November. In contrast, Italy and other European countries will have to wait until the last Sunday of March for their transition to summer time. This annual change has been in place since 2007 when the U.S. government decided to move the start of DST forward by a few weeks to take advantage of additional daylight hours, potentially improving energy efficiency.
This year, the clocks in the U.S. were set forward one hour between Saturday, March 7 and Sunday, March 8, meaning that at 2 AM, clocks were moved to 3 AM. The only exceptions to the DST rule in the U.S. are Hawaii and most of Arizona, which do not observe this time shift. The intention behind the Uniform Time Act, which governs this change, is primarily aimed at energy conservation by allowing for longer daylight at the end of the day. With the delayed sunset, an extra hour of natural light is available, which can help reduce reliance on artificial lighting and various energy consumption during the evening hours.
