ONTONAGON, MICHIGAN

Ontonagon is a village in Michigan. The population was 1,494 at the 2010 census. Ontonagon is the westernmost incorporated community in the United States in the legally designated Eastern Time Zone as determined by the United States Department of Transportation. In the summer the sun sets over Lake Superior at 10 p.m. local time with dusk lasting until almost 11 p.m. By contrast in the winter the sun does not rise until just before 9 a.m. and it is still pitch black at 8 a.m. Ontonagon is within one degree of longitude to the east of the 90th meridian west, which is actually the meridian for the Central Time Zone. Therefore, Ontonagon is geographically situated in the Central Time Zone, not the Eastern Time Zone. As a result of this idiosyncrasy, Ontonagon actually has its solar noon occur either at or near 1 p.m. during the winter when standard time (EST) is being observed and 2 p.m. when daylight saving time (EDT) is being observed. The same is true for solar midnight, which occurs at or near 1 a.m. while on standard time and 2 a.m. while on daylight saving time.
