Ancient civilizations adjusted daily schedules to the sun. For example, Roman water clocks had different amounts of times for different months in the year. Rome's third hour from sunrise, hora tertia, started at 09:02 solar time and lasted 44 minutes in the winter solstice, but in the summer solstice started at 06:58 and lasted 75 minutes. Unequal hours are still used in a few traditional settings, such as some Mount Athos monasteries in Greece.
In 1784, Benjamin Franklin proposed taxing the use of shutters and candles, or ringing church bells to wake up lazy people who were sleeping late on the morning during the summertime. However, Benjamin Franklin did not propose adjusting the clocks because, like ancient Rome, 18th-century Europe did not keep precise schedules on that time. Much later, communication networks required time standardization, and travel required people to be on time.
"Early to bed, early to rise, makes a man healthy, wealthy, and wise." — Benjamin Franklin
Then on 1895, George Hudson, from New Zealand, proposed Daylight Savings Time (DST) in a paper to a philosophical society. He argued that people could take better advantage of the daylight if they got up two hours earlier in summer mornings. On April, 17, 1916, Brandon, Manitoba became the first location in the world to use DST. Shortly after that, in April 1916, Germany and its World War I allies began DST as a way to conserve coal during wartime. The Allies and the US adopted DST in the end of the war in 1918. Since then, the world has seen many adjustments to DST.
A move to "permanent daylight saving time" (staying in summer hours all year with no time shifts) is sometimes talked about. In fact, the United Kingdom stayed on daylight saving time from 1968 to 1971. However, quite a few countries have never used DST such as Afghanistan, Indonesia, Kenya, Nigeria, Venezuela. Similarly, equatorial countries, like Ecuador, find no benefit to the time change as they have an equal number of daylight hours on summer and in winter.
