The season to change to Daylight Saving Time (DST) is coming, and while most gadgets nowadays automatically adjust their clocks to follow this scheme, some may still be curious as to the exact time DST will take place.

Simply put, DST will happen on the second Sunday of March, or March 11 to be exact. By 2 a.m on this date, the clocks will be set one hour forward. As mentioned earlier, some gadgets will automatically set their clocks to follow the scheme, but in some states, it may be much more complicated than that.

The state of Hawaii does not observe Daylight Saving Time, so residents of that area should be aware in case their clocks set themselves forward automatically. Also, in most parts of Arizona where temperatures can reach up to 115 to 120 degrees Fahrenheit, DST is not observed.

More interesting, though, is the area within Arizona called the Navajo Reservation, which does observe DST. Meanwhile, there is still an area within that Reservation called the Hopi Reservation, which does not observe DST.

It is a rather complicated rule, but one could imagine that there are three concentric areas that alternate in DST observance: the larger Arizona has no DST, the Navajo Reservation observes DST, and finally, the Hopi Reservation has no DST.

Of course, as the clocks go forward an hour, they are bound to go back. This happens on the first Sunday of November, or Nov. 4, 2018, to be precise.

It is widely believed that Benjamin Franklin proposed the idea of DST by saying Americans could conserve candles if they went to bed "an hour earlier," but the actual pioneer of the practice is said to be William Willet. It was first approved by the English Parliament as British Summer Time (BST), and Americans later adopted their own version, which is now known as DST.
