If the early bird truly does get the worm, you'd better be to work by 7:48 a.m. or earlier if you work in the Omaha metro.
That's the median start of the workday here, according to Census Bureau data crunched by data guru Nate Silver at his blog fivethirtyeight.com.
Silver, a former New York Times blogger who is perhaps best-known for accurately predicting how each U.S. state would vote in an electoral map for the 2012 presidential election, broke out data from the Census Bureau's American Community Survey to show when American cities begin work.
The median start time of the U.S. workday is 7:55 a.m., and New York City has the latest median start time at 8:24 a.m.
The median workday in St. Louis begins at 7:50 a.m. and it starts at 7:51 a.m. in Kansas City and Milwaukee.
Up and at 'em before any other city is Hinesville, Ga., home of the U.S. Army's 3rd Infantry Division and Fort Stewart, which has a median workday start time of 7:01 a.m.
