Americans will gain an extra hour of sleep this weekend as Sunday marks the end of daylight saving time.
At 2:00 a.m. on November 1st, people across the U.S. will need to turn their clocks back one hour to reflect the new time.
However, residents of Arizona, Hawaii and many of the U.S. territories do not practice daylight saving time and it will not affect them.
Legislation to make daylight savings time permanent has been introduced in more than 15 states, but it can’t be enacted without congressional approval.
Daylight Saving Time was invented to make the best use of daylight hours.
According to NASA, Benjamin Franklin created the concept and it has been used throughout much of the U.S., Canada and Europe since World War One.
