As I pointed out in the last Chicago Sunrise Chart, tomorrow morning the sun will rise in Chicago at 7:30:11, the latest sunrise in most people's lifetimes. I found only one occasion from 1975 to 2040 when the sun rises later: at 7:30:35 on 6 November 2032.
The last time the sun rose after 7:30 was at 7:31:26 on 26 February 1974, after Chicago started daylight saving time on 6 January 1974, due to the oil crisis. Chicago also observed year-round daylight saving time during World War II, from 9 February 1942 until 30 September 1945. Chicago's latest-ever sunrise occurred at 8:19:17 on 4 January 1943.
Think about that when you whine about the time change. We only get 9 hours of daylight on most December days; you really want to go to work entirely in the dark?
