The United States spans several civil time zones, most of which observe daylight saving time.
US local time depends on both longitude and season. Eastern, Central, Mountain, and Pacific zones are the four used by the cities on this site. Hawaii and most of Arizona follow different rules and are not represented by the continental zones above. Always convert with an IANA identifier such as America/New_York rather than a three-letter abbreviation alone.
United States uses America/New_York, America/Chicago, America/Denver, America/Los_Angeles. Current offsets: UTC-04:00, UTC-05:00, UTC-06:00, UTC-07:00.
Some or all regions in United States observe daylight saving. Check a city page for the live status; dates come from IANA timezone data.
