Time in United States
The exact time in United States is based on the time zones for United States. We will always try to give you the exact time for United States. There might be slight differences, since the time zones for United States might change due to daylight savings time (DST).
Time changes in United States are usually done to adapt citizen and tourist activity to the solar cycle. This allows for greater usage of daylight, reducing dependency on electricity. That is why the time is sent ahead one hour in the spring for United States, and falls back one hour in the fall for United States. Adding an extra hour of daylight helps United States to improve its tourism and depend less on United States's electricity supplies.
