An early proposal for daylight saving time changed the clock eight times a year.

Every year, people in many parts of the world set their clocks forward an hour each spring at the beginning of daylight saving time (DST), and then back an hour in the fall. One of the first people to seriously advocate adjusting the clock seasonally was a British builder named William Willett, who had noticed that few people were out in the early morning light during the summer, and his golf games often ended early when the sky became dark. But his idea worked a little differently than the “spring forward” and “fall back” time changes many observe today.

In his 1907 self-published pamphlet “The Waste of Daylight,” Willett wrote, “The sun shines upon the land for several hours each day while we are asleep, and is rapidly nearing the horizon, having already passed its western limit, when we reach home after the work of the day is over.” To maximize time spent during the daylight hours, he suggested changing the clocks at 2 a.m. on Sundays during the spring and fall — something we still do today. But, unlike today, the transition was to happen 20 minutes at a time over the course of four weeks, twice a year, for a total of eight time changes each year. And rather than an even hour, the time difference would be 80 minutes. Willett’s proposal was considered in the British House of Commons in 1908, but it was met with derision and soundly rejected. 

During World War I a decade later, many countries were looking for new ways to save money. Inspired by Willett’s original proposal, which had included estimated savings in electricity costs, Germany and Britain implemented “Summer Time” in 1916, changing the clocks just one hour twice a year. The United States followed suit, first observing daylight saving time on March 31, 1918.
