Live local times across the U.S.

One city per zone. The gaps between them shift with daylight saving; the DST map has the 2026 dates.

The six U.S. time zones

  • Hawaii–Aleutian Time

    UTC−10

    UTC−10 year-round, with no daylight saving. The furthest-behind zone in the United States; in summer it is six hours behind Eastern Time (five hours in winter).

  • Alaska Time

    UTC−9 / UTC−8

    One hour behind Pacific Time, for nearly all of Alaska — Anchorage, Fairbanks, and Juneau. Only the western Aleutian Islands use Hawaii–Aleutian Time.

  • Pacific Time

    UTC−8 / UTC−7

    The westernmost continental zone: California, Washington, nearly all of Nevada and Oregon, and the northern panhandle of Idaho.

  • Mountain Time

    UTC−7 / UTC−6

    Colorado, Utah, New Mexico, Montana, Wyoming, and Arizona, plus southern Idaho and the western edges of Kansas, Nebraska, the Dakotas, and Texas.

    Mountain map

  • Central Time

    UTC−6 / UTC−5

    The hub zone: Illinois, Texas, Minnesota, and 17 more states in all or part. Ten states straddle its edges, from Texas and the Dakotas to Florida and Michigan.

    Central map

  • Eastern Time

    UTC−5 / UTC−4

    The densest zone: New York to Maine, plus most of the Mid-Atlantic and Southeast. Florida, Indiana, Kentucky, Michigan, and Tennessee each have parts on Central Time.

How the zones came to be

Five dates behind every clock on this map, from sundials to daylight saving.

Before 1883

Sun time

Every town set its clocks by the sun overhead, so noon in Boston came about twelve minutes before noon in New York, and railroads juggled dozens of local times.

November 18, 1883

Railroad time

U.S. and Canadian railroads switched to standard zones an hour apart, set from Greenwich. Many towns reset their clocks the same day, remembered as “the day of two noons.”

1884

Greenwich

Delegates at the International Meridian Conference in Washington chose the Greenwich meridian as longitude zero — the line every UTC offset on this site is counted from.

1918 and 1966

Time by law

The Standard Time Act made the zones federal law in 1918. The Uniform Time Act of 1966 set common daylight-saving rules and let a state opt out, as Arizona and Hawaii do.

Daylight saving

Since 2007 clocks spring forward on the second Sunday of March and fall back on the first Sunday of November: March 8 and November 1 this year.

Frequently asked questions

What does “live” mean here?

Every clock on the page updates from your device’s own time zone database — no server time. The map, city markers, and dashboard all reflect the current moment.

Are daylight saving times handled?

Yes — because the offsets are derived from the IANA database, a zone that’s in DST shows its daylight offset automatically. No seasonal table to get stale.

How often do the times update?

City clocks tick every second; the overall map repaints on a 30-second cycle to keep it efficient without battery drain.
