Daylight saving time is the convention of advancing clocks so that afternoons have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn; the ancients lengthened summer hours instead. Presaged by a 1784 satire, modern DST was first proposed in 1907 by William Willett, and 1916 saw its first widespread use as a wartime measure aimed at conserving coal. Despite controversy, many countries have used it since then; details vary by location and change occasionally. Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours, but causes problems for farmers and other workers whose hours depend on the sun. Extra afternoon daylight cuts traffic fatalities; its effect on health and crime is less clear. DST is said to save electricity by reducing the need for artificial evening lighting, but the evidence for this is weak and DST can boomerang by boosting peak demand, increasing overall electricity costs. DST's clock shifts complicate timekeeping and can disrupt meetings, travel, billing, medical devices, and heavy equipment.

Sun Tzu was an ancient Chinese military general, strategist and philosopher who is traditionally believed to be the author of The Art of War, an influential ancient Chinese book on military strategy. Sun Tzu has had a significant impact on Chinese and Asian history and culture, both as an author of The Art of War and through legend. Sun Tzu, also known as Sun Tze or Sun Wu in other translations, was a historical figure whose authenticity is questioned by historians. This is a Chinese name which would usually mean the family name comes first however "Zi" (子; "Tzu" in Wade–Giles transliteration) was used as a suffix for the family name of a respectable man in ancient Chinese culture. In this case, 子 "Tzu" is not the personal or family name. It is a rough equivalent to "Sir" and is commonly translated into English as "Master". Traditional accounts place him in the Spring and Autumn period of China (722–481 BC) as a military general serving under King Helü of Wu, who lived c. 544–496 BC. Modern scholars accepting his historicity place the completion of The Art of War in the Warring States period (476–221 BC), based on the descriptions of warfare in the text, and on the similarity of text's prose to other works completed in the early Warring States period. Traditional accounts state that his descendant, Sun Bin, also wrote a treatise on military tactics, titled Sun Bin's Art of War. Both Sun Wu and Sun Bin were referred to as Sun Tzu in classical Chinese writings, and some historians believed that Sun Wu was in fact Sun Bin until Sun Bin's own treatise was discovered in 1972. During the 19th and 20th centuries, Sun Tzu's The Art of War grew in popularity and saw practical use in Western society. His work continues to influence both Asian and Western culture and politics.
