Daylight Saving Time (DST) begins early Sunday morning March 11, 2018. Please set your clocks forward one hour Saturday night. The main purpose of Daylight Saving Time (called “Summer Time” in many places in the world) is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening. Most areas of the United States observe daylight saving time, the exceptions being Arizona (except for the Navajo, who do observe daylight saving time on tribal lands), Hawaii, and the overseas territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. Florida’s State House and State Senate approved a bill to permanently move that state to DST but the State’s Governor has yet to sign it into law.
Approximately 70 countries utilize Daylight Saving Time in at least a portion of the country and have different change dates. Japan, India, and China are the only major industrialized countries that do not observe some form of daylight saving.
According to some sources, DST saves energy and many people believe that DST could be linked to fewer road accidents and injuries. Also, the extra hour of daylight in the evening is said to give children more social time and can boost the tourism industry because it increases the amount of outdoor activities.
