About time in Green Bay
Green Bay is the seat of Brown County and the northernmost of Wisconsin's larger cities, on Central Time like the whole state. Just across the bay's north shore, Menominee County is one of the four Michigan Upper Peninsula counties that also keep CT, while the rest of Michigan runs an hour ahead.
The Packers make the zone arithmetic familiar nationwide: a Lambeau Field game promoted nationally for 1:00 PM Eastern kicks off at noon on Green Bay clocks.
At 44.5° N, daylight stretches to about 15 hours 33 minutes in late June with sunsets near 8:40 PM CDT, then contracts to roughly 8 hours 50 minutes by the December solstice.
