List of U.S. states by time zone
From Wikipedia, the free encyclopedia
This is a list of United States of America States by time zone. For more about the time zones of the U.S. and other time zones see: time zone. Most of the U.S. has Daylight Saving Time (DST), so states that have DST are not marked as such and states that don't have DST are clearly marked as such. This is the opposite of how it is marked in the time zone article.
