Current Dates and Times across USA

Across the United States of America, Daylight Savings Time is now in effect.

Daylight Saving Time is not observed in Hawaii, and by most of Arizona. In summer, local time in Arizona is the same as Pacific Daylight Time (PDT). In the winter Arizona is on Mountain Standard Time (MST).

Alaska (AK) 90% of Alaska is (1 hour) behind the Pacific Time Zone, while the far reaches of the Aleutian Islands use Hawaii-Aleutian time.

Important (current time) Exceptions: Parts of Florida, Idaho, Indiana, Kansas, Kentucky, Michigan, Nebraska, North Dakota, Oregon, South Dakota, Tennessee and Texas are in two time zones.

UTC and GMT, an update

The worldwide standard for coordinated universal time, formerly known as GMT (Greenwich Mean Time), is now abbreviated as UTC (Coordinated Universal Time).

Some sources still refer to it as UTC/GMT and some web browsers, e.g. Mozilla Firefox, still display it as GMT.

The UTC Time (shown directly below) is the standard time zone upon which all other worldwide time zones are based. It never observes daylight saving time.
