How does United States handle time?

The United States covers six primary civil time zones in current use, from Eastern at UTC-5 through Hawaii–Aleutian at UTC-10. The four contiguous zones (Eastern, Central, Mountain, Pacific) plus Alaska observe daylight saving from the second Sunday of March to the first Sunday of November under the federal Uniform Time Act of 1966. Hawaii and most of Arizona (the Navajo Nation excepted) do not observe DST. The Indiana patchwork was resolved in 2006 with most of the state moving to Eastern. Outlying territories add further zones (Guam, American Samoa, Puerto Rico).

What are the working hours in United States?

Standard US working hours run 09:00 to 17:00 across most office sectors, but timezone-spanning operations routinely begin earlier on the East Coast (financial markets open 09:30 Eastern) and run later on the West Coast (entertainment industry overlap with East Coast scheduling). Lunch is typically short, often eaten at the desk. Federal public holidays cluster around Memorial Day in late May, Independence Day on 4 July, Labor Day in early September, Thanksgiving on the fourth Thursday of November, and Christmas. Many sectors close on the day after Thanksgiving informally.

Where is United States?

The United States covers around 9.8 million square kilometres across the central swathe of North America, plus Alaska to the north-west and Hawaii in the central Pacific. The population is roughly 335 million, concentrated heavily along the Atlantic and Pacific coasts and around the Great Lakes. The continental span from Boston to San Francisco is around 4,400 kilometres, with Anchorage a further 3,500 kilometres north-west and Honolulu around 3,800 kilometres south-west of the mainland. The federal system distributes substantial timezone and DST authority to individual states.
