The timezones in the United States
There are several timezones in the United States. Countries with a large distance from West to East are often devided into two or more timezones to adjust daytimes to the position of the sun. Timezones are always computed relatively to UTC, the "Universal Time Coordinated".
In the United States exists a time difference of up to 5 hours between the East and the West. Like in most parts of the USA, there is a distinction in the United States drawn between standard time and daylight saving time (also called winter time and summer time), but this distiction is not nationwide. 8 regions put the clocks forward by 1 hour in summer. 2 regions keep the standard time year-round.
The next clock change in New York will be on March 14th, 2021 at 2:00 to daylight saving time.
