(NBC) -- The bi-annual ritual of adjusting our clocks is upon us again.
Overnight Saturday into Sunday, we leave Daylight Saving and revert back to Standard Time.
Seeing how we're really just shifting time, some find it odd that we don't call it Daylight Shifting Time.
The name has been in place since early last century.
The concept for was first developed by founding father Benjamin Franklin back in 1784.
Franklin was in Paris at the time serving as an American diplomat.
"One day, he awakened early and he saw the sunlight shining through his window and he realized that if he and everyone else in Paris would wake up earlier, closer to sunrise, you could use the sun to light your house rather than expensive and smoky candles," explains Dr. David Prerau, author of "Seize the Daylight".
Franklin brought the idea back to the new world, but it never caught on until the lean years of World Wars One and Two when saving everything, including energy, was almost compulsory.
In 1966 Congress standardized the six-month period states could observe Daylight Saving Time, extended it in 1986 and again to nearly eight months in 2007.
None of this is of any interest to the people of Arizona, Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands or the Northern Mariana Islands.
Those places don't observe Daylight Saving Time.
