Which states do not observe Daylight Saving Time?

Hawaii does not observe Daylight Saving Time and neither does Arizona (although the Navajo Nation, in northeastern Arizona, does). For many years, most of Indiana did not observe Daylight Saving Time with the exception of 10 counties. Beginning in 2006, all of Indiana now observes Daylight Saving Time.  None of the US dependencies observe DST. This includes American Samoa, Guam, Puerto Rico, Northern Mariana Islands, the US Minor Outlying Islands, and the US Virgin Islands.
