List of U.S. states by time zone

Map of the U.S. with time zones.

This is a list of United States of America States by time zone. For your convenience they have been put in the order of the U.S.A. postal abreviatons. For much more about the time zones of the U.S. and the 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 haven't DST are clearly marked as such. This is the opposite of how it is marked in the time zone article.
