Important Things To Know
Currency
The currency used in the USA is the US dollar.
National Languages
The national language spoken in the USA is English.
Time Zone
Because the country is so big, different states have different time zones. As such the USA has six time zones: Alaska time, Central time, Eastern time, Hawaii-Aleutian time, Mountain time, and Pacific time.
The USA also observes daylight savings between the second Sunday in March and the first Sunday in November, where the clocks are set forward by one hour.
Climate And Weather
The USA is a big country, so the climate is vastly different from region to region.
The southern states, and states along the west coast, generally experience pleasant weather with warm temperatures throughout the year. The states up north, closer to Canada, do have much colder climates.
The central regions and northeastern states tend to experience fairly hot summers and cold winters, with a clear distinction between the seasons.
Alaska is a bit of an outlier, as it has extremely long, cold winters and very short, mild summers.
