Time zones and clock changes
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.
Holiday and working-day notes
Federal holidays apply nationwide to federal offices, but state holidays, school calendars and private-employer schedules can differ. Regional dates are not automatically treated as non-working days.
Planning accurately
For cross-state calls, always select the actual city and date: daylight-saving rules and zone boundaries matter more than the country label.
Use the date-aware converter for future meetings and the working-days calculator for date ranges.
