Local time details
How time works here
The contiguous United States uses Eastern, Central, Mountain and Pacific time, while Alaska and Hawaii use additional zones. Most areas observe daylight saving time, while Hawaii and most of Arizona do not, so differences can change during the year.
Planning note
For cross-state calls, always select the actual city and date: daylight-saving rules and zone boundaries matter more than the country label.
