Wisconsin operates on Central Standard Time (CST) during winter months, which is 6 hours behind Coordinated Universal Time (UTC-6). During daylight saving time, observed from the second Sunday in March to the first Sunday in November, Wisconsin switches to Central Daylight Time (CDT), which is UTC-5.
All of Wisconsin follows the same time zone. Major cities including Milwaukee, Madison, Green Bay, Kenosha, and Racine all observe Central Time. This makes scheduling across Wisconsin straightforward, as there's no time difference within the state.
Wisconsin is in Central Time alongside Chicago. When it's 9 AM in Milwaukee, it's 10 AM in New York and 7 AM in Los Angeles. Wisconsin's manufacturing sector coordinates operations with both coasts from this central timezone position.
