Center for Data Innovation: “The Washington Post has created a series of visualizations showing how keeping daylight savings time all year around would affect sunrise and sunset times across the United States. One visualization groups sunrise times into half-hour increments from 7:30 a.m. to 10 a.m., shown by increasingly darker colors, and displays the correlating color across the country. For example, if Daylight Savings Time is made permanent, the sun won’t rise in some parts of Montana, North Dakota and Michigan until after 9:30 a.m. on the days with the latest sunrise.”
