Wisconsin • Live Time-Zone Reference

Wisconsin Time Zone

Wisconsin uses Central Time (CT) statewide. Milwaukee, Madison, Green Bay, Kenosha, Racine, Eau Claire, La Crosse and all 72 Wisconsin counties share the same official civil time. Wisconsin uses CST at UTC−06:00 during standard time and CDT at UTC−05:00 during daylight saving time.

Quick answer: Wisconsin has one time zone and no internal time-zone boundary. Use America/Chicago for date-aware software calculations. Even Wisconsin's Lake Superior shore, Door Peninsula and western Mississippi River counties use the same Central Time clock.

Do Wisconsin Borders Change the Clock?

No at ordinary direct land crossings under current rules. Illinois, Minnesota and Iowa use Central Time along Wisconsin's borders. Michigan is a two-zone state, but the four Michigan counties that directly border Wisconsin by land—Gogebic, Iron, Dickinson and Menominee—are also Central Time. Eastern Time appears farther into Michigan.

Wisconsin Standard Time vs Daylight Time

Wisconsin currently observes the U.S. daylight-saving schedule statewide. In 2026 the state advanced clocks on March 8 and returns to standard time on November 1.

How Wisconsin Time Works

Six facts explain nearly every Wisconsin time-zone question, from statewide Central Time to all 72 counties, border travel, IANA calculations, state statutes and the 2025–2026 permanent-standard-time bills.

01 · Statewide

Wisconsin Has One Time Zone

The entire state uses Central Time. There is no Eastern or Mountain Time area inside Wisconsin.

02 · Counties

All 72 Counties Share One Clock

Every Wisconsin county follows the same CST/CDT schedule, from Douglas and Door to Grant and Kenosha.

03 · Cities

Milwaukee & Madison Always Match

Milwaukee, Madison, Green Bay, Eau Claire, La Crosse and every other Wisconsin community share one official clock.

04 · Borders

Direct Land Borders Stay on Central Time

Even the Michigan counties directly adjoining Wisconsin are on the Central side of Michigan's zone boundary.

05 · IANA

Use America/Chicago

America/Chicago is the correct date-aware IANA zone for current and future Wisconsin civil-time calculations.

06 · Wisconsin Law

§§ 175.09 & 175.095 Define Central Time + DST

Wisconsin law establishes Central Time as the state standard and advances it one hour during the statutory daylight-saving period.

Does All of Wisconsin Have the Same Time?

Yes. All 72 Wisconsin counties use Central Time. Those counties are Adams, Ashland, Barron, Bayfield, Brown, Buffalo, Burnett, Calumet, Chippewa, Clark, Columbia, Crawford, Dane, Dodge, Door, Douglas, Dunn, Eau Claire, Florence, Fond du Lac, Forest, Grant, Green, Green Lake, Iowa, Iron, Jackson, Jefferson, Juneau, Kenosha, Kewaunee, La Crosse, Lafayette, Langlade, Lincoln, Manitowoc, Marathon, Marinette, Marquette, Menominee, Milwaukee, Monroe, Oconto, Oneida, Outagamie, Ozaukee, Pepin, Pierce, Polk, Portage, Price, Racine, Richland, Rock, Rusk, St. Croix, Sauk, Sawyer, Shawano, Sheboygan, Taylor, Trempealeau, Vernon, Vilas, Walworth, Washburn, Washington, Waukesha, Waupaca, Waushara, Winnebago and Wood.

Wisconsin Statute § 175.09 describes the state's standard as the time of the 90th meridian west of Greenwich, commonly known as Central Time. Current § 175.095 then advances that standard by one hour from 2:00 a.m. on the second Sunday in March until 2:00 a.m. on the first Sunday in November.

Is Wisconsin Ending Daylight Saving Time?

No change is in force as of August 20, 2026. Wisconsin still alternates between CST and CDT under §§ 175.09 and 175.095. The 2026 daylight-saving period began March 8 and ends November 1.

AB 160 and SB 165 in the 2025–2026 Legislature proposed repealing § 175.095 and eliminating daylight saving time, which would have left Wisconsin on Central Standard Time year-round. The Legislative Reference Bureau analysis noted that federal law allows a one-zone state such as Wisconsin to choose standard time throughout the entire state. Both companion bills ultimately failed to pass on March 23, 2026, so Wisconsin's current seasonal clock changes remain in effect.

Visual Geography

Wisconsin Time Zone Map

Wisconsin is entirely in Central Time, but a dedicated state map is useful for border context—especially the Wisconsin–Michigan relationship. The four Michigan counties that directly border Wisconsin by land are also Central Time, while Michigan's Eastern Time territory begins farther east.

Sources & Methodology

CalendarHours uses location-aware, date-aware time-zone logic rather than permanently hardcoding Wisconsin as UTC−6 or UTC−5. America/Chicago supplies the modern Central Time rules used throughout the state.

The IANA Time Zone Database is the primary rules source for civil offsets and transitions. U.S. daylight-saving dates are checked against NIST. Wisconsin's 72-county structure is checked against Wisconsin state agencies. The state's time law is checked against Wisconsin Statutes §§ 175.09 and 175.095, and the most recent permanent-standard-time proposal against the 2025–2026 AB 160/SB 165 legislative record.
